Anti tigit mbsa43

Manufactured by Thermo Fisher Scientific

Anti-TIGIT (MBSA43) is a mouse monoclonal antibody that binds to the TIGIT (T-cell immunoreceptor with Ig and ITIM domains) protein. TIGIT is an inhibitory receptor expressed on various immune cells, including T cells, NK cells, and regulatory T cells. The Anti-TIGIT (MBSA43) antibody can be used for research purposes to study the role of TIGIT in immune regulation and its potential therapeutic applications.

Cells were stained with LIVE/DEAD Fixable Near-IR Dead Cell Stain kit (Invitrogen) and surface antibodies for 30 min at 4 °C. For intracellular cytokine staining, cells were treated with 50 nM phorbol-12-myristate-13-acetate (MilliporeSigma) and 250 nM ionomycin (MilliporeSigma) for 4 hours in the presence of Brefeldin A (BD Biosciences) before harvesting. Cells were washed and fixed with BD Cytofix™ Fixation Buffer (BD Biosciences) for 10 min at RT, then washed with PBS. Intracellular cytokines were stained in permeabilization buffer (eBioscience) for 30 min at 4 °C. The following antibodies were used: anti-LAG-3 (11C3C65, BioLegend), anti-PD-1 (EH12.1, BD Biosciences), anti-TIGIT (MBSA43, eBioscience), anti-Tim-3 (F38–2E2, Biolegend), anti-IFN-γ (4S.B3, eBioscience), and IL-10 (JES3–9D7, Biolegend). Cells were acquired on a BD Fortessa flow cytometer and data was analyzed with FlowJo software v10 (Threestar).

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
