TIGIT Mouse Monoclonal Antibody [Clone ID: 4A5]

Specifications

Product Data
Clone Name	4A5
Applications	ELISA, FC
Reactivity	Human
Host	Mouse
Clonality	Monoclonal
Immunogen	The original antibody was generated by immunizing 9 week old BALB/c mice with recombinant human TIGIT extracellular region Fc fusion protein in complete Freund's adjuvant.
Specificity	This antibody binds the extracellular domain of the human TIGIT (T cell immunoreceptor with Ig and ITIM domains). TIGIT is a type I transmembrane protein that is a member of the CD28 family within the Ig superfamily of proteins. It is an immune receptor present on some T cells and natural killer cells (NK). It binds the poliovirus receptor (PVR) with high affinity which causes increased secretion of IL10 and decreased secretion of IL12B and suppresses T-cell activation by promoting the generation of mature immunoregulatory dendritic cells. The binding characterization of this antibody towards human TIGIT was done using ELISA and flow cytometry. This antibody can bind human TIGIT extracellular domain Fc fusion protein in an ELISA and is also capable of recognizing TIGIT expressed on HEK293 cells by flow cytometry. The original IgG1 version of this antibody binds human TIGIT with a binding affinity of Kd=3.732 X 10^(-10) M. This antibody was also reported to successfully block the binding of TIGIT to its ligand CD155. This antibody is capable of binding NK cells in vitro. The anti-cancer activity of this antibody was tested on ovarian cancer cell HO8910, human non-small cell lung cancer cell NCl-H358 and human non-small cell lung cancer cell NCl-H1650 (CN109384846).
