| CD22, or cluster of differentiation-22, is a molecule belonging to the SIGLEC family of lectins. It is found on the surface of mature B cells and to a lesser extent on some immature B cells. CD22 a member of the immunoglobulin superfamily. CD22 functions as an inhibitory receptor for B cell receptor (BCR) signaling. It is also involved in the B cell trafficking to Peyer's patches in mice. |
| Recombinant Human Siglec-2/CD22 Protein is expressed from Expi293 with hFc tag at the C-terminal. It contains Asp20-Arg687. |
