Invitrogen™ Kit ELISA de TIM-1 (HAVCR1) humaine

Description

The Human TIM-1 (HAVCR1) ELISA quantitates Hu TIM-1 in human serum, plasma, or cell culture medium. The assay will exclusively recognize both natural and recombinant Hu TIM-1. Principle of the method The Human TIM-1 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.

CD365 also known as T-cell immunoglobulin and mucin domain 1 (Tim-1) is a type 1 surface glycoprotein that consists of extracellular N-terminal immunoglobulin V-like domain and a mucin domain, and a short cytoplasmic tail. The endogenous ligand for CD365 is Tim-4. In addition, CD365 is known to be a cellular receptor or co-receptor for a number of viruses including hepatitis A and C viruses, Ebola virus, Marburg virus, Dengue virus, Zika virus, West Nile virus, and Japanese encephalitis virus. The direct binding of the viruses by CD365 occurs via phosphatildyl-serine exposed on viral envelopes. Polymorphisms within human CD365 gene (HAVCR1) are associated with susceptibility to infection and the disease severity. CD365 has also been implicated in the T cell co-stimulation. CD365 is primarily expressed in epithelial cells. It is also highly expressed in A549, 769-P and Caco-2 and cell lines. CD365 exists also as a soluble protein generated by metalloproteinase mediated proteolytic cleavage of the surface protein.
