What is IHC reagent?
Immunohistochemistry (IHC), or the staining of tissue with immunological substances, is a step wise process of staining, detection, and preservation that relies upon many factors to yield remarkable results.
What are IHC stains used for?
An Introduction to IHC Staining IHC is used in histology to detect the presence of specific protein markers that can assist with accurate tumor classification and diagnosis. IHC has evolved to complement the Hematoxylin & Eosin (H&E) and Special Stain techniques that typically show tissue morphology (structure).
How do you optimize IHC staining?
Tips for IHC Optimization
- Prepare tissues appropriately.
- Consider the need for antigen retrieval.
- Understand staining patterns.
- Select primary antibodies wisely.
- Incorporate directly conjugated primary antibodies.
- Optimize every step.
- Stay up to date with new techniques.
Can I use an ICC antibody for IHC?
Yes you can do it. Be aware that the secondary antibody should be from two different species if you do double labeling.
How much does immunohistochemistry cost?
The immunohistochemical test would cost $250, assuming a $50 cost per antibody. If there is a 10% gain in diagnostic certainty, the cost-effectiveness ratio is $25 (cost per percentage gain in diagnostic certainty ratio = test cost/gain in diagnostic certainty = $250/10%).
What is the cost of IHC test in India?

What is DAB reagent?
DAB (3,3′-Diaminobenzidine) is a derivative of benzene. It is most often used in immunohistochemical (IHC) staining as a chromogen. It is also used in in situ hybridization (ISH) and sometimes in dot blots and in western blotting.
What is HRP in IHC?
Horseradish peroxidase (HRP) is a 44-kDa protein that catalyzes the oxidation of substrates in the presence of hydrogen peroxide, resulting in a colored product or the release of light as one product of the reaction (chemiluminescence).
How much does a laboratory cost?
Even if going for minimum specifications and cheapest equipment models, for the above one should budget for at least Rs 5-7 lakhs of investment. If however you are considering refurbished/ used equipment, costs could be half or 65% of the above.
How do I verify IHC?
2. Steps to validation
- 2.1. Step 1: Understand target.
- 2.2. Step 2: Identify cell and tissues.
- 2.3. Step 3: Choose an appropriate IHC method.
- 2.4. Step 4: Identify level of validation required.
- 2.5. Step 5: Control of IHC.
- 2.6. Step 6: Publication of results.
How do you authenticate an antibody?
Standard antibody validation methods include western blot, ELISA, flow cytometry, and IHC. Most researchers are comfortable with these tried-and-true methods. The validation process can be time-consuming because the researcher or the manufacturer must validate the antibody for each application.
