Three samples with differing target protein concentrations were assayed using four different lots to measure the CV% lot to lot variance.
To assay reproducibility, three samples with differing target protein concentrations were assayed using four different lots.

*The typical data is obtained from Boster's internal QC result and for reference only. It may differ from the lab test results of the end users. It is more important that the user's lab test results reflect the same linearity demonstrated in the typical data than achieving exactly the same O.D. values.

|Background||Interleukin-12(IL12; formerly NKSF, for natural killer cell stimulatory factor, or CLMF, for cytotoxic lymphocyte maturation factor) is a novel cytokine cloned from B-cell lines. IL-12 is a heterodimeric molecule composed of p35 and p40 subunits. The larger 40-kDa subunit(p40) is a member of the cytokine receptor family, and the smaller 35-kDa subunit(p35) is related to IL6 and GCSF. Both IL-12 p40(-/-) and p35(-/-) mice fail to produce IL-12 p70 heterodimer. Interleukin(IL)-12 has been cloned on the basis of its ability to activate natural killer(NK) cells and promote the development of cytolytic T cells. With further understanding of its activities, IL-12 has emerged as an important cytokine, affecting both immune and hematologic functions. It has been shown to be necessary for the T cell independent induction of interferon(IFN)-gamma, critical for the initial suppression of bacterial and parasitic infection; for the development of a Th1 response, critical for effective host defense against intracellular pathogens; and for the activation of differentiated T lymphocytes of both CD4+ and CD8+ phenotype. The subunits map to different chromosomes: p40(IL12B) to 5q31-q33 and p35(IL12A) to 3p12-3q13.2.2 The standard product used in this kit is recombinant human IL-12(p40), which is a 40KDa glycoprotein consisting of 306 amino acids.|
