Human CD22 also known as cluster of differentiation-22, and SIGLEC-2, GenBank Accession No. NM_001771, a.a. 100-330 fused to Fc region of Human IgG1. This protein is enzymatically biotinylated using AviTag technology and expressed in a HEK293 cell expression system. MW = 104 kDa. This protein runs at a higher MW by SDS-PAGE due to glycosylation.
