| Product Name: |
Recombinant Human CD19 Protein, LIgG2b Fc-tagged, low endotoxin |
| Product Overview: |
Recombinant Human CD19 Protein, LIgG2b Fc-tagged, low endotoxin is expressed from human 293 cells (HEK293). It contains AA Pro 20 - Lys 291 (Accession # P15391-1). Predicted N-terminus: Pro 20. This protein carries a llama IgG2b Fc tag at the C-terminus. The protein has a calculated MW of 57.9 kDa. The protein migrates as 70-100 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation. |
