Instrumentation
What is continuous access?
Most autostainers on the market do not allow for the addition of new samples for staining when a run is in progress. Xmatrx Diagnostics breaks this limitation by enabling continuous operation of the system. The user can add new slides in the middle of a run if empty slide positions are available. The slides that are loaded in continuous mode will be processed along with the current slides without affecting the current run. Continuous Access enables the user to remove completed slides and load new ones without the need to wait for run completion. In addition, reagents that are no longer required can be removed and new ones can be added.
What is STAT access? How is it different from continuous access?
STAT (Latin: statum, meaning: to rush, urgent) Access allows the addition of emergency specimen slides for staining during an ongoing run. STAT slides will be processed and completed at the highest priority. During the processing of STAT slides, all other slides being processed shall remain on hold and are buffered regularly to keep the tissue hydrated. After completion of the STAT slides, all pending slides that are on hold will be processed according to their protocol.
What is the microwave pressure cooker protocol and what are its advantages?
The microwave pressure cooker method is a procedure that utilizes a microwave with a pressure cooker for antigen retrieval and staining. The pressure cooker sold by BioGenex is especially designed for use in a microwave oven. Its advantages include the speed of treatment, reproducibility of results with large batches of slides, ability to use metal slide racks, and economy of equipment costs.
How do I determine which antigen retrieval solution to use with my antibody?
BioGenex provides information on the specific antigen retrieval solution recommended for use with its primary antibodies. We offer Retrievit Sampler Kit for use with primary antibodies from other manufacturers. This kit provides the customer with five different antigen retrieval solutions so the user can determine which one is the best for that particular antibody.
Can we customize the EZ-Retriever® protocol as per the research requirement?
While using the EZ-Retriever®System for antigen retrieval, you have the facility to increase and decrease the temp and time according to your need. You can use 107 Deg C maximum temperature and 15 mins maximum time in one cycle with BioGenex antigen retrieval solutions {HK521 (EZ-AR™ 1), HK546 (EZ-AR™ 1 Elegance), HK522(EZ-AR™ 2), HK547 (EZ-AR™ 2 Elegance)}. If you are using other solutions then you can use it at 95 Deg C for 10 min in one cycle.

The one-step detection kit is designed with proprietary technology which eliminates the use of Super Enhancer required by the two-step detection kit. Therefore, the one-step kit provides superior sensitivity and specificity with the advantage of a short protocol.
How would I choose the correct secondary antibodies?
Most primary antibodies raised in mouse (IgG +IgM) and rabbit (IgG) work with our Poly-HRP Secondary antibody. In case of primary antibodies raised in other species, we also provide species-specific secondary antibodies for use with our Link-Label System.
Why is an antibody discontinued? Do you have any replacement for the same?
There are various reasons as to why we discontinue certain antibodies ranging from raw material issues to insufficient sales. The replacement products, if available, can be provided on request.
Where can I find the protein concentration of BioGenex antibody?
For concentrated antibodies, the protein concentration is available on the data sheet for that specific antibody. Ready-to-Use (RTU) antibodies are pre-diluted for optimal staining results. We can provide the concentration of RTU antibodies upon request.
Ancillary Reagents
Why can’t we re-use Citra and Citra plus antigen retrieval solution?
Evaporation in Citra and Citra plus antigen retrieval solution is more and its ph also changes after use that’s why these can not be reused again and again.
What is the difference between the normal antigen retrieval and EZ Elegance antigen retrieval solutions?
The proprietary technology used in the EZ-AR Elegance solutions provides stronger intensity and reproducible results. These solutions are designed for used with automated platforms such as Xmatrx systems and the EZ Retriever. The normal antigen solutions are intended for use with manual protocols.
Is antigen retrieval required for frozen and de-calcified tissues?
The requirement of antigen retrieval depends on the antibody used and its staining protocol. For frozen and de-calcified tissues, heat-based antigen retrieval is NOT recommended. We provide alternate solutions for these kinds of tissues such as the Decal Retrieval Solution for acid-decalcified bone marrow tissue and enzymes for tissue digestion.
Which chromogen can be used with which antibody?
Most antibodies can be used either with DAB or AEC chromogen depending on the preference for staining under a light microscope.
Would the chromogen be based on mounting technique?
The choice of mounting medium following immunochemical staining is largely dictated by the chromogen label used to visualize the antigen. Compatible Mounting Media for Chromogens and Counterstains
| Counterstains | AEC | BCIP/NBT | DAB | Elegance Red | Fast Red | New Fuchsin |
| Hematoxylin | Aqueous/ SuperMount | Aqueous /Not recommended | Aqueous/ Permanent/ SuperMount | Aqueous/ Permanent/ SuperMount | SuperMount / Aqueous | SuperMount |

What is Immunohistochemistry?
Immunohistochemistry is a well-established, highly specific and sensitive method that allows the localization of an antigen within a cell or any other biological tissue samples with high resolution. The bound antigen-antibody complexes are then visualized using chemically linked enzymes, dyes, or fluorescent labels.
What is the purpose of Immunohistochemistry?
Immunohistochemistry is used to help diagnose diseases, such as cancer. It may also be used to tell the difference between different types of cancer.
What are the common steps of Immunohistochemistry?
- Baking
- Deparaffinization and rehydration
- Antigen Retrieval
- Peroxide Blocking/Endogenous peroxidaseblocking
- Power Blocking/Protein Blocking
- Primary Antibody
- Super Enhancer/Linker
- Poly-HRP/ Secondary Antibody/ Label
- DAB
- Counter staining
- Dehydration, Clearing and mounting
Note– If one is using one step poly HRP then “vii” point is not applicable.
What is used to preserve tissues for IHC staining?
10% Neutral Buffered Formalin
What is the tissue thickness generally required for IHC?
3-5µ
What is commonly used to remove paraffin from IHC slides?
Biogenex provides Dewax solution for deparaffinization. It is a non-toxic solution. Commonly Xylene is used but it is a toxic solution.
What is the purpose of antigen retrieval?
The process of sample fixation can lead to protein cross-linking, which masks antigens and can restrict antigen-antibody binding. Antigen retrieval enables an antibody to access the target protein within the tissue.
What are the methods of antigen retrieval?
- Enzymatic/proteolytic antigen retrieval
- Heat-induced antigen retrieval method
What is Polyclonal antibody?
These are antibodies against many epitopes of one antigen
What is Monoclonal Antibody?
These are antibodies against single epitope of single antigen
What is antigen?
These are foreign molecules to which the body may be exposed and respond with a reaction specifically and bind to the antigen. These are typically proteins or polysaccharides within or on the surface of cell.
What are some of the most popular ways of visualizing antibody-antigen interaction?
Antibody is conjugated to an enzyme, such as peroxidase, that can catalyze a color-producing reaction. Antibody can be tagged to a fluorophore, such as fluorescein (immunofluorescence)
What are the common enzymes used in immunohistochemistry?
- Horseradish peroxidase (HRP)
- Alkaline phosphatase
What is the purpose of using ISH/In Situ Hybridization?
In Situ Hybridization (ISH) is a powerful technique for precise detection and localization of a specific nucleic acid sequence within a histologic section.
What is the underlying principle behind ISH?
The nucleic acids within a histologic specimen can be detected by the hybridization of a complementary nucleic acid probe in which a reporter molecule is attached. Common non-radioactive labels for probe are fluorescein and digoxigenin. Subsequent visualization of the reporter molecule localizes DNA or RNA sequences in tissue or cells samples.
What are the different approaches of ISH?
There are two basic approaches to visualize the DNA or RNA target sequences in situ: chromogenic in situ hybridization (CISH) and fluorescence in situ hybridization (FISH). While these approaches involve the same underlying principle, the instrumentation required to visualize the specimen is different.
Which instruments are used for ISH visualization?
- Chromogenic ISH: Bright field microscope
- FISH: Fluorescence microscope
What are the uses of ISH & FISH?
ISH- ISH has broad applications such as physical chromosome mapping, karyotyping, and pathogen profiling. Riboprobe also enables the localization and analysis of gene expression profile.
FISH- As a diagnostic tool, FISH is widely used in clinical genetics, neuroscience, reproductive medicine, toxicology, microbial ecology, evolutionary biology, comparative genomics, cellular genomics and chromosome biology to check for genetic abnormalities associated with prenatal diagnosis, cancer, birth defects and mental retardation. It is possible to differentiate benign and malignant tumors in the same tissue using FISH.

What is the difference between IHC & IF?
Both IHC (Immunohistochemistry) and IF (Immunofluorescence) have same functions. However, IF is the staining method usually used for multiplexing, particularly when co-localization is required or when 2 or more than 2 different antibodies needs to be detected on a single tissue.
IF follows the protocol same like IHC with slight modifications. The basic differences between IHC and IF is the use of fluorescent tagged (conjugated) antibodies in IF which may have colors like FITC, PE, Cy3, Cy5, Texas Red etc. are attached either with primary antibodies or secondary antibodies. After that there is no chromogen required here and final mounting with DAPI follows. For visualization, fluorescent microscope is also required.

Yes
Are BioGenex detection kits can be used for IF?
No. The customer has to purchase fluorescent tagged secondary antibodies from other companies.
For visualization of IF slides is there any specific microscope required?
Yes, fluorescent microscope with specific filters depending upon fluorescent colors that the customer is using for their study.
