Sandwich ELISA analysis of Human IL-12 Biotinylated Antibody (Product # M121B) was performed using the Thermo Scientific Human IL-12 (p70) ELISA Kit (Product # EHIL12) by loading 50µl per well of Human IL-12 Biotinylated Antibody (Product # M121B) in duplicate at 0.03125µg/ml dilution and 50µl per well of Human IL-12 (p70) ELISA Standard (Product # SIL12) in duplicate at 600, 240, 96, 38.4, 15.4, 0 pg/ml across a pre-coated plate of Human IL-12 MAb (Product # M122) at 7µg/ml dilution and incubated for 3 hours at room temperature. The plate was washed then incubated with 100µl per well of Streptavidin-HRP (Product # N504) in all test wells at 1:3,000 dilution for 30 minutes at room temperature followed by 100µl per well of TMB substrate for 30 minutes at room temperature in the dark. The plate was stopped with 0.16M sulfuric acid. Absorbances were read on a spectrophotometer at 450-550nm.

M121B targets IL-12 in ELISA, and WB applications and shows reactivity with Human samples.
The M121B immunogen is recombinant human IL-12 (p70).
M121B detects IL-12 which has a predicted molecular weight of approximately 23 kDa.
The M121B IL12 antibody (biotinylated conjugate of clone C8.6) has successfully been paired as the detection antibody in a sandwich ELISA with capture antibody M122 (clone 20C2). Typical dilutions for sandwich ELISA include 1 µg/ml for coating and 0.125 - 0.25 µg/ml for detection.
Biotinylated antibody M121B (clone C8.6) and antibody M122 (clone 20C2) have successfully been used in combination with recombinant IL12 p70 protein SIL12 in ELISA applications.
This antibody is produced by injecting Rat IgG secreting hybridoma cells into the peritoneum of mice. The resulting ascites is collected from the mice and the antibody is purified.
This gene encodes a subunit of a cytokine that acts on T and natural killer cells, and has a broad array of biological activities. The cytokine is a disulfide-linked heterodimer composed of the 35-kD subunit encoded by this gene, and a 40-kD subunit that is a member of the cytokine receptor family. This cytokine is required for the T-cell-independent induction of interferon (IFN)-gamma, and is important for the differentiation of both Th1 and Th2 cells. The responses of lymphocytes to this cytokine are mediated by the activator of transcription protein STAT4. Nitric oxide synthase 2A (NOS2A/NOS2) is found to be required for the signaling process of this cytokine in innate immunity.
