Recombinant Human CD19, Fc-tagged, Biotinylated

• Cat.No.: CD19-280H
• Product Overview: Biotinylated Human CD19 Protein, With C-Fc Tag (Biotinylated rhCD19-Fc) Pro 20 - Lys 291, was labeled with biotin based on rhCD19-Fc Protein, which was produced in human 293 cells (HEK293).

Specification

• Species: Human
• Source: HEK293
• Tag: Fc
• Protein Length: 20-291 a.a.
• Description: Lymphocytes proliferate and differentiate in response to various concentrations of different antigens. The ability of the B cell to respond in a specific, yet sensitive manner to the various antigens is achieved with the use of low-affinity antigen receptors. This gene encodes a cell surface molecule which assembles with the antigen receptor of B lymphocytes in order to decrease the threshold for antigen receptor-dependent stimulation.
• Form: Lyophilized from 0.22 μm filtered solution in PBS, pH7.4. Normally Trehalose are added as protectants before lyophilization.
• Molecular Mass: Biotinylated rhCD19-Fc, fused with Fc fragment of human IgG1 at the C-terminus, has a calculated MW of 56.3 kDa. The predicted N-terminus is Pro 20. DTT-reduced Protein migrates as 56-66 kDa due to glycosylation.
• Endotoxin: Less than 1.0 EU per μg of the Biotinylated rhCD19-Fc by the LAL method.
• Purity: >95% as determined by reduced SDS-PAGE.
• Storage: Avoid repeated freeze-thaw cycles. No activity loss was observed after storage at: In lyophilized state for 1 year (4°C); After reconstitution under sterile conditions for 3 months (-70°C).
