Product Description |
Recombinant Human CD21 Protein is expressed from HEK293 with His tag at the C-Terminus.It contains Ile21-Arg971. |
Product 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. |
