Validation Data Gallery

• 

  Purity of GMP recombinant human IL-1 beta was determined by SDS- polyacrylamide gel electrophoresis. The protein was resolved in an SDS- polyacrylamide gel in reducing and non-reducing conditions and stained using Coomassie blue.

• 

  Recombinant human IL-1 beta (Cat no: HZ-1164-GMP) stimulates dose-dependent induction of alkaline phosphatase production in a HEK293 reporter cell line. Alkaline phosphatase production was assessed using pNPP as a chromogenic substrate. The EC50 was determined using a 4- parameter non-linear regression model. Activity determination was conducted in triplicate on a validated bioassay. The EC50 values range from 0.8-4.0 ng/mL EC50.

Background

Interleukin-1 is a pro-inflammatory cytokine with multiple biological effects. The IL-1 gene family encodes three proteins: IL-1α, IL-1β and their naturally occurring inhibitor Il-1RN. Interleukin 1β(IL-1β), mainly produced by blood monocytes and tissue macrophages, has been implicated in mediating both acute and chronic inflammation. IL-1β is known to be involved in a variety of cellular activities, including cell proliferation, differentiation and apoptosis. IL-1β is emerging as a key mediator of carcinogenesis that characterizes host-environment interactions (PMID: 8630372; PMID: 12401481; PMID: 23704929; PMID: 24618930).
