 IL12B 組成成分
Capture Ab:1 mg/mL of rabbit anti-Human IL12B / IL-12B monoclonal antibody (in PBS, pH 7.4). Dilute to a working concentration of 1 μg/mL in PBS before coating. (Catalog: # 10052-MM05)
檢測抗體:0.2 mg/mL of mouse anti-Human IL12B / IL-12B monoclonal antibody conjugated to horseradish-peroxidase (HRP) (in PBS, 50 % HRP-Protector, pH 7.4, store at 4℃). Dilute to working concentration of 0.4 μg/mL in detection antibody dilution buffer before use. (Catalog: # 10052-R054)
標準品:Each vial contains 24 ng of recombinant Human IL12B / IL-12B. Reconstitute with 1 mL detection antibody dilution buffer. After reconstitution, store at -20℃ to -80℃ in a manual defrost freezer. A seven-point standard curve using 2-fold serial dilutions in sample dilution buffer, and a high standard of 1000 pg/mL is recommended.
 IL12B 檢測靈敏度
The minimum detectable dose of Human IL12B / IL-12B was determined to be approximately 15.625 pg/ml. This is defined as at least three times standard deviations above the mean optical density of 10 replicates of the zero standard.
 IL12B 產品介紹
The Human IL12B / IL-12B ELISA Pair Set is for the quantitative determination of Human IL12B / IL-12B.
The Sino Biological ELISA Pair Set is a solid phase sandwich ELISA (Enzyme-Linked Immunosorbent Assay). It utilizes a monoclonal antibody specific for Human IL12B / IL-12B coated on a 96-well plate. Standards and samples are added to the wells, and any Human IL12B / IL-12B present binds to the immobilized antibody. The wells are washed and a horseradish peroxidase conjugated mouse anti-Human IL12B / IL-12B monoclonal antibody is then added, producing an antibody-antigen-antibody "sandwich". The wells are again washed and TMB substrate solution is loaded, which produces color in proportion to the amount of Human IL12B / IL-12B present in the sample. To end the enzyme reaction, the stop solution is added and absorbances of the microwell are read at 450 nm.

IL12B/IL-12B 研究背景

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.
