CD21, His, Human

CD21, His, Human

CD21 mRNA expression, an EBV-entry receptor, was transiently detected in NK cells after exosome treatment, and levels decreased after further culture. CD21 protein expression was also transiently transferred to NK cells after co-culture with an EBV-positive Burkitt lymphoma cell line (Raji) via trogocytosis. However, EBV did not infect NK cells through CD21-mediated trogocytosis.

Purity > 95% as determined by Bis-Tris 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 CD21, His, Human at 1μg/ml (100μl/well) on the plate can bind Anti-CD21 Antibody, hFc Tag. Test result was comparable to standard batch.
Expression System HEK293
Theoretical Molecular Weight 105.3 kDa
Apparent Molecular Weight Due to glycosylation, the protein migrates to 110-130 kDa based on Bis-Tris PAGE result.
Formulation Lyophilized from a 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.

Background
Target Background CD21 mRNA expression, an EBV-entry receptor, was transiently detected in NK cells after exosome treatment, and levels decreased after further culture. CD21 protein expression was also transiently transferred to NK cells after co-culture with an EBV-positive Burkitt lymphoma cell line (Raji) via trogocytosis. However, EBV did not infect NK cells through CD21-mediated trogocytosis.
