Performs great without variability
immunohistochemistry
This antibody is very effective and works 100% of the time. We have had success at very high dilution in our Automated system and is pretty sensitive. Never had any issues with detection. Cost effective and reproducible.

The IHC antibody that every researcher dreams of.
Immunohistochemistry
This antibody is the best IHC antibody we have ever owned!. The results are specific and extremely reproducible in murine and human tissues. We use it with Vector's Vectastain ABC kit and we get no background at all. We have tried different lots and they all have the same amazing performance. I wish all antibodies worked this well! We haven't used it for other assays, such as Western blotting, though.
