Sandwich ELISA analysis of human IL-1b was performed using a Human IL-1b Colorimetric ELISA Kit (Product # EH2IL1B) by loading 50 ul per well of Human IL-1b Recombinant Protein (Product # SIL1B) in quadruplicate at 400, 160, 64, 25.6, 10.24 and 0 pg/ml across a 5 ug/ml mouse anti-human IL-1b (Product # M421B) pre-coated plate and incubating for 3 hours at room temperature. The plate was washed, then incubated with 50 ul per well of a biotinylated-mouse anti-human IL-1b (Product # M420BB) in quadruplicate at 0.07 ug/ml for 3 hours at room temperature. The plate was washed and incubated with 100 ul per well of Ultra Streptavidin-HRP (Product # N504) in all test wells at 1:3000 for 30 minutes at room temperature. Detection was performed using 1-Step Ultra TMB Substrate (Product # 34028) for 30 minutes at room temperature in the dark. The plate was then stopped with 0.16M sulfuric acid. Absorbances were read on a spectrophotometer at 450-550 nm.

M421B targets IL-1 beta in ELISA, and WB applications and shows reactivity with Human samples.
A precipitate may be present in the solution. Mix for at least five seconds prior to use.
M421B detects IL-1 beta which has a predicted molecular weight of approximately 31 kDa.
The M421B IL1b antibody (clone ILB1-H67) has successfully been paired as the coating antibody in a sandwich ELISA with detection antibody M420BB (biotinylated conjugate of clone ILB1-H6). Typical dilutions for sandwich ELISA include 1 µg/ml for coating and 0.125 - 0.25 µg/ml for detection.
Antibody M421B (clone ILB1-H67) and biotinylated antibody M420BB (clone ILB1-H6) have successfully been used in combination with recombinant IL1 beta protein SIL1B in ELISA applications.
The protein encoded by this gene is a member of the interleukin 1 cytokine family. This cytokine is produced by activated macrophages as a proprotein, which is proteolytically processed to its active form by caspase 1 (CASP1/ICE). This cytokine is an important mediator of the inflammatory response, and is involved in a variety of cellular activities, including cell proliferation, differentiation, and apoptosis. The induction of cyclooxygenase-2 (PTGS2/COX2) by this cytokine in the central nervous system (CNS) is found to contribute to inflammatory pain hypersensitivity. This gene and eight other interleukin 1 family genes form a cytokine gene cluster on chromosome 2.
