Invitrogen™ Human SIGLEC9 ELISA Kit

Description

The Human Siglec-9 ELISA quantitates Hu Siglec-9 in human serum, plasma, or cell culture medium. The assay will exclusively recognize both natural and recombinant Hu Siglec-9. Principle of the method The Human Siglec-9 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.

SIGLEC9 (Sialic acid-binding Ig-like lectin 9) is a putative adhesion molecule that mediates sialic-acid dependent binding to cells. It contains two Ig-like C2 type (immunoglobulin-like) domains and one Ig-like V-type (immunoglobulin-like) domain. It preferentially binds to alpha2, 3-or alpha2, 6-linked sialic acid. The sialic acid recognition site may be mased by cis interactions with sialic acids on the same cell surface.
