Human T cell immunoreceptor with Ig and ITIM domains (TIGIT) ELISA Kit

TIGIT encodes a member of the PVR (poliovirus receptor) family of immunoglobin proteins. The product of this gene is expressed on several classes of T cells including follicular B helper T cells (TFH) . The protein has been shown to bind PVR with high affinity; this binding is thought to assist interactions between TFH and dendritic cells to regulate T cell dependent B cell responses. The predicted 244-amino acid TIGIT protein has a single Ig domain, followed by a type I transmembrane domain and a single intracellular immunoreceptor tyrosine-based inhibitory motif. It shares 88%, 67%, and 58% amino acid identity with its rhesus, dog, and mouse homologs, respectively.

Human T cell immunoreceptor with Ig and ITIM domains (TIGIT) ELISA Kit has high sensitivity and excellent specificity for detection of Human TIGIT. No significant cross-reactivity or interference between Human TIGIT and analogues was observed.

This Human T cell immunoreceptor with Ig and ITIM domains (TIGIT) ELISA Kit employs a two-site sandwich ELISA to quantitate TIGIT in samples. An antibody specific for TIGIT has been pre-coated onto a microplate. Standards and samples are pipetted into the wells and anyTIGIT present is bound by the immobilized antibody. After removing any unbound substances, a biotin-conjugated antibody specific for TIGIT is added to the wells. After washing, Streptavidin conjugated Horseradish Peroxidase (HRP) is added to the wells. Following a wash to remove any unbound avidin-enzyme reagent, a substrate solution is added to the wells and color develops in proportion to the amount of TIGIT bound in the initial step. The color development is stopped and the intensity of the color is measured.

• Do not mix components from different kit lots or use reagents beyond the kit expiration date.• Allow all reagents to warm to room temperature for at least 30 minutes before opening.• Pre-rinse the pipet tip with reagent, use fresh pipet tips for each sample, standard and reagent to avoid contamination.• Unused wells must be kept desiccated at 4 °C in the sealed bag provided.• Mix Thoroughly is very important for the result. It is recommended using low frequency oscillator or slight hand shaking every 10 minutes.• It is recommended that all samples and standards be assayed in duplicate or triplicate.
