Etigilimab

Catalog No.: AT0018

Etigilimab is a humanized IgG1 monoclonal antibody that blocks the interaction between TIGIT and its ligand CD155 (PVR), a key pathway in immune checkpoint regulation. By inhibiting TIGIT signaling, Etigilimab enhances T cell–mediated immune responses and is widely used in tumor immunology research and checkpoint blockade studies.

Useful Calculator

This calculator helps you calculate mass of compound based on solution concentration, volume and molecular weight in a specific solution using the formula:

Mass (mg) = Concentration (mM) × Volume (mL) × Molecular Weight (g/mol)

* Please check COA/MSDS for correct molecular weight.

Calculate the dilution required to prepare a stock solution.
This equation is commonly abbreviated as: C₁V₁ = C₂V₂

Frequently Asked Questions

What are Biosimilar Antibodies?

Biosimilar antibodies are research-grade recombinant antibodies designed to closely resemble approved therapeutic antibodies in terms of amino acid sequence, structural characteristics, and biological activity. These antibodies are generated using recombinant expression technologies and retain the same variable regions as their corresponding reference therapeutics, thereby preserving target specificity and binding affinity. Owing to these properties, biosimilar antibodies serve as reliable and cost-effective research reagents for applications in drug discovery, pharmacological studies, and basic biomedical research. Research-grade biosimilar antibodies have been successfully expressed and functionally validated against a wide range of widely studied targets. These antibodies can be directly utilized as positive control reagents in drug discovery programs, as well as reference tools for rapid verification of the biological functions of target proteins in biochemical and cellular assays.
