BTN3A1/CD277, Human

BTN3A1/CD277, Human

The three butyrophilin BTN3A molecules, BTN3A1, BTN3A2, and BTN3A3, are members of the B7/butyrophilin-like group of Ig superfamily receptors, which modulate the function of T cells. BTN3A1 controls activation of human Vγ9/Vδ2 T cells by direct or indirect presentation of self and nonself phosphoantigens (pAg).

Product Introduction
Species Human
Protein Construction
BTN3A1/CD277 (Gln30-Gly254)
Accession # O00481-1
Purity > 95% as determined by Bis­Tris PAGE 
> 95% as determined by HPLC
Endotoxin Level Less than 1EU per μg by the LAL method.
Biological Activity Measured by its binding ability in a functional ELISA. Immobilized BTN3A1/CD277, Human at 0.5μg/ml (100μl/well) on the plate can bind Anti­BTN3A1 Antibody, hFc Tag. Test result was comparable to standard batch.
Expression System HEK293
Theoretical Molecular Weight 24.15 kDa
Apparent Molecular Weight Due to glycosylation, the protein migrates to 26-32 kDa based on Bis-Tris PAGE result.
Formulation Lyophilized from 0.22 μm filtered solution in PBS (pH 7.4).
Reconstitution Centrifuge the tube before opening. Reconstituting to a concentration more than 100 μg/ml is recommended. Dissolve the lyophilized protein in distilled water.
Storage & Stability Upon receiving, the product remains stable up to 6 months at -20 °C or below. Upon reconstitution, the product should be stable for 3 months at -80 °C. Avoid repeated freeze-thaw cycles.
