Biolegend, 508208, Alexa Fluor® 647 anti-human IL-1β Antibody, 100tests

IL-1 refers to two proteins, IL-1α and IL-1β which are the products of distinct genes, but which are recognized by the same cell surface receptors. IL-1β is a potent immuno-modulator which mediates a wide range of immune and inflammatory responses including the activation of B and T cells. The JK1B-1 antibody reacts with human interleukin-1β (IL-1β) and baboon IL-1β. The JK1B-1 antibody does not recognize mouse IL-1β or human IL-1α or other cytokines. The JK1B-1 antibody can neutralize the bioactivity of natural or recombinant IL-1β.

Q: Does this clone recognize the pro or mature form of IL-1 beta?
A: The monoclonal anti-human IL-1b antibody clone H1b-98 was generated and screened using the mature form of IL-1b as the immunogen. Since the pro-form contains the mature sequence, it is believed that the antibody also recognize pro-IL-1beta. Similarly, we believe clone JK1B-1 should also recognize both pro and mature forms of IL-1b. However, this information has not been confirmed with in-house testing data.
