Human IL-3 ELISA kit is a procedure for analysing in vitro quantitative levels of interleukin-3 (IL-3) in human plasma (heparin, EDTA, citrate), tissue homogenates, serum and other biological fluid samples. This assay has a minimum detection limit of 9.375 pg/ml.
Interleukin-3 (IL-3) is essentially a hematopoietic colony-stimulating factor (CSF) which has the ability to support the proliferation of a large number of hematopoietic cell types. It is a protein that is 140 amino acids in length which is chemically synthesised using an automated peptide synthesiser and this displays biological activities that can be attributed to native IL-3.
The gene IL-3 in known to encode interleukin 3, where the human gene encoding IL-3 is found to be tandemly arrayed on the long arm of chromosome 5. The mouse interleukin-3 gene is located on chromosome 11 and the cDNA sequence for codes for a polypeptide of 166 amino acids including a putative signal peptide. It is regarded as one of the colony stimulating factors that is vital in regulating haematopoiesis.
