Invitrogen™ SDF-1 beta/CXCL12B Human ELISA Kit

Sandwich ELISA Kit

Brand:  Invitrogen™ EHCXCL12BX5

Product Code. 17165409

Description

The Human SDF-1beta/CXCL12B (SDF-1β) ELISA quantitates Hu SDF-1β in human serum, plasma, or cell culture medium. The assay will exclusively recognize both natural and recombinant Hu SDF-1β. Principle of the method The Human SDF-1β solid-phase sandwich ELISA (enzyme-linked immunosorbent assay) is designed to measure the amount of the target bound between a matched antibody pair. A target-specific antibody has been pre-coated in the wells of the supplied microplate. Samples, standards, or controls are then added into these wells and bind to the immobilized (capture) antibody. The sandwich is formed by the addition of the second (detector) antibody, a substrate solution is added that reacts with the enzyme-antibody-target complex to produce measurable signal. The intensity of this signal is directly proportional to the concentration of target present in the original specimen. Rigorous validation Each manufactured lot of this ELISA kit is quality tested for criteria such as sensitivity, specificity, precision, and lot-to-lot consistency. See manual for more information on validation.

CXCL12 is a stromal cell-derived alpha chemokine member of the intercrine family. This gene product and its receptor CXCR4 can activate lymphocytes and have been implicated in the metastasis of some cancers such as breast cancer. Mutations in this gene are associated with resistance to human immunodeficiency virus type 1 infections. Multiple transcript variants encoding different isoforms have been found for this gene.
