Form

Lyophilized powder
Note: We will preferentially ship the format that we have in stock, however, if you have any special requirement for the format, please remark your requirement when placing the order, we will prepare according to your demand.

Buffer

Lyophilized from a 0.2 μm filtered 20 mM Tris-HCl, 0.5 M NaCl, 6% Trehalose, pH 8.0

Reconstitution

We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Please reconstitute protein in deionized sterile water to a concentration of 0.1-1.0 mg/mL.We recommend to add 5-50% of glycerol (final concentration) and aliquot for long-term storage at -20°C/-80°C. Our default final concentration of glycerol is 50%. Customers could use it as reference.

Troubleshooting and FAQs

Description

CD96 functions as an emerging immune checkpoint receptor that competes with TIGIT for binding to shared ligands, making it a compelling target in immuno-oncology and T-cell regulation studies. This recombinant human CD96 construct covers the extracellular region (aa 22–503 of Isoform 2), encompassing the ligand-binding immunoglobulin-like domains, and is expressed in mammalian cells to preserve native glycosylation and conformational integrity critical for receptor-ligand interaction assays. Functional ELISA validation confirms robust binding activity, with immobilized CD96 at 2 μg/mL engaging anti-CD96 antibody at an EC50 of 95.78–127.1 ng/mL, supporting use as a positive control in binding assays, competitive blocking antibody screening, and therapeutic antibody epitope mapping. The C-terminal 10×His tag facilitates oriented immobilization for SPR or BLI affinity characterization, while purity exceeding 95% and endotoxin levels below 1.0 EU/μg satisfy the criteria typically required for sensitive immune checkpoint research and small-molecule inhibitor screening campaigns.

Target Background

Function

May be involved in adhesive interactions of activated T and NK cells during the late phase of the immune response. Promotes NK cell-target adhesion by interacting with PVR present on target cells. May function at a time after T and NK cells have penetrated the endothelium using integrins and selectins, when they are actively engaging diseased cells and moving within areas of inflammation.
