The Human IL-1 F6 ELISA kit is an in-vitro enzyme-linked immunosorbent assay for the quantitative measurement of human IL-1 F6 in serum (human IL-1 F6 concentration is pretty low in normal serum/plasma, and it may not be detected in this assay), plasma (collect plasma using EDTA and Citrate as anticoagulants; Heparin is not recommended for use in this assay) and cell culture supernatants.
