Interleukin 16(IL-16) is a cytokine that released by a variety of cells(including lymphocytes and some epithelial cells) that has been characterized as a chemoattractant for certain immune cells expressing the cell surface molecule CD4. By Southern blot analysis and PCR using a human/rodent somatic cell hybrid mapping panel, The human IL16 is encoded by a single-copy gene on chromosome 15. Using a combination of STS-content mapping, radiation-hybrid mapping, and genetic mapping, it was refined the assignment to 15q26.1. The mouse Il16 gene was mapped to chromosome 7 in a region showing homology of synteny to human 15q26.1. IL-16 was originally described as a factor that could attract activated T cells in humans, it was previously called lymphocyte chemoattractant factor(LCF), and the augmentation of IL16stimulation by CCR5 plays a role in regulation of Th1 cell recruitment and activation at sites of inflammation.

Useful in Sandwich ELISA for Quantitative Detection of Antigen. Aliquot 0.1ml per well of the 2000pg/ml, 1000pg/ml, 500pg/ml, 250pg/ml, 125pg/ml, 62.5pg/ml, 31.2pg/ml human IL-16 standard solutions into the precoated 96-well plate. Add 0.1ml of the sample diluent buffer into the control well (Zero well). Add 0.1ml of each properly diluted sample of human cell culture supernates, serum and plasma(heparin, EDTA) to each empty well. It is recommended that each human IL-16 standard solution and each sample be measured in duplicate.
