    Customer reviews and Q&As


    According to the datasheet, this antibody is indeed a non-purified cell culture supernatantproduct. That means, along with whole serum and Ascitesproducts, the antibody concentration cannot be determined as there are too many other proteins in this solution as well.

    However, we have a table under our Technical FAQs (Question 8, What concentration of primary antibody should I use?) which explains how much specific antibody can be expected in the non-purified products. In this case it is 1 - 3 mg/ml.
