Human IL-4 ELISA Kit
This ELISA kit was used for quantification of IL-4 in the supernatants of human CD4⁺ T helper cells treated with experimental immunomodulatory compounds. ELISA kit instructions were easy to follow and displayed high sensitivity. Overall, I would recommend this product.

We ordered two of these kits and they arrived in good condition and good packaging. The minimum detectable dose of this kit is 5 pg/mL, which is pretty good! The protocol demands lot of washing steps, but that is necessary. Overall, I would recommend this product.
