|0.5 mg/mL of mouse anti-IL12B monoclonal antibody. Dilute to a working concentration of 2.0 μg/mL in CBS before coating.|
|0.4 mg/mL biotinylated rabbit anti-IL12B monoclonal antibody. Dilute to working concentration of 0.5 μg/mL in detection antibody dilution buffer before use.|
|Each vial contains 9 ng of recombinant IL12B. Reconstitute standard powder with 1 mL detection antibody dilution buffer. After reconstitution, store at -20℃ to -80℃ in a manual defrost freezer. A seven-point standard curve usi ng 2-fold serial dilutions in sample dilution buffer, and a high standard of 500 pg/mL is recommended.|
|50 μL of streptavidin conjugated to horseradish-peroxidase. 1:2000 Dilution in detection antibody dilution buffer before use.|
|The minimum detectable dose of human IL12B (NKSF2 / p40) was determined to be approximately 7.8125 pg/ml. This is defined as at least three times standard deviations above the mean optical density of 10 replicates of the zero standard.|
The human IL12B (NKSF2 / p40) ELISA Pair Set is for the quantitative determination of human IL12B.
This ELISA Pair Set contains the basic components required for the development of sandwich ELISAs.
The Sino Biological ELISA Pair Set is a solid phase sandwich ELISA (Enzyme-Linked Immunosorbent Assay). It utilizes a monoclonal antibody specific for IL12B ( NKSF2 / p40) coated on a 96-well plate. Standards and samples are added to thewells, and any IL12B (NKSF2 / p40) present binds to the immobilized antibody.The wells are washed and a horseradish peroxidase conjugated rabbit anti-IL12B monoclonal antibody is then added, producing anantibody-antigen-antibody "sandwich". The wells are again washed and TMBsubstrate solution is loaded, which produces color in proportion to the amountof IL12B (NKSF2 / p40) present in the sample. To end the enzyme reaction, thestop solution is added and absorbances of the microwell are read at 450 nm.

Subunit beta of interleukin 12 (also known as natural killer cell stimulatory factor 2, or cytotoxic lymphocyte maturation factor 2, p40) (IL12B) is a subunit of human interleukin 12. IL12B/IL-12B is a cytokine that acts on T and natural killer cells, and has a broad array of biological activities. Interleukin 12 is a disulfide-linked heterodimer composed of the 40 kD cytokine receptor like subunit encoded by this gene, and a 35 kD subunit encoded by IL12A. IL12B/IL-12B is expressed by activated macrophages that serve as an essential inducer of Th1 cells development. This cytokine has been found to be important for sustaining a sufficient number of memory/effector Th1 cells to mediate long-term protection to an intracellular pathogen. Overexpression of this gene was observed in the central nervous system of patients with multiple sclerosis (MS), suggesting a role of this cytokine in the pathogenesis of the disease. The promoter polymorphism of this gene has been reported to be associated with the severity of atopic and non-atopic asthma in children. IL12B/IL-12B associates with IL23A to form the IL-23 interleukin, an heterodimeric cytokine which functions in innate and adaptive immunity.
