Recombinant TIGIT antibody

Catalog No. ABIN7072458

Product Details anti-TIGIT Antibody

Target: TIGIT (T Cell Immunoreceptor with Ig and ITIM Domains (TIGIT))

Antibody Type: Recombinant Antibody

Reactivity: Mouse

Host: Rabbit

Clonality: Chimeric

Conjugate: This TIGIT antibody is un-conjugated

Application: Flow Cytometry (FACS), Agonist (Agon)

Purpose: Anti-TIGIT [4D4], Rabbit IgG, kappa

Specificity: 4D4 specifically recognises TIGIT.

Characteristics:

Original Species of Ab: Hamster, Armenian

Original Format of Ab: IgG

Purification: Protein A affinity purified

Immunogen: Armenian hamsters were immunized with recombinant mouse TIGIT tetramers by a combination of s.c. and food pad immunization and booster injections. Draining lymph nodes were fused with Sp2/0-Ag14 cells, selected in HAT (hypoxanthine/aminopterin/thymidine) medium and supernatants were screened for specificity by ELISA and flow cytometry using TIGIT-transfectants.

Clone: 4D4

Isotype: IgG kappa

Application Details

Application Notes: 4D4 is an agonistic anti-TIGIT antibody, and addition of plate bound 4D4 to anti-CD3/anti-CD28 stimulated T cells was shown to inhibit their proliferation (Joller 2011). Further, 4D4 has been used in order to identify genes that are downstream of TIGIT signaling in Tregs, as TIGIT engagement might modulate the Treg phenotype in tumor tissue (Liu 2016).

Comment:

This chimeric rabbit antibody was made using the variable domain sequences of the original Hamster format, for improved compatibility with existing reagents, assays and techniques.
