| Molecular Weight | The recombinant mature human CD45/Fc chimeric protein consists of 629 amino acids and has a calculated molecular mass of 71.1 kDa. In SDS-PAGE under reducing conditions, the apparent molecular mass of rhCD45/Fc monomer is approximately 125-135 kDa due to glycosylation. |
| predicted N | Gln 24 |
| SDS-PAGE |  |
| Purity | > 95 % as determined by SDS-PAGE |
| Protein Construction | A DNA sequence encoding the human CD45 precursor (NP_563578.1) (Met 1-Lys 414) was fused with the Fc region of human IgG1 at the C-terminus. |
| Bio-activity | Measured by its ability to bind biotinylated human Galectin-1 (P10290-HNAE-E) in a functional ELISA. |
| Research Area | Cancer |Signal transduction |Phosphatase & Regulator |Phosphatase Regulator |
| Formulation | Lyophilized from sterile PBS, pH 7.4 1. Normally 5 % - 8 % trehalose, mannitol and 0.01% Tween80 are added as protectants before lyophilization. Specific concentrations are included in the hardcopy of COA. |
| Background | The cluster of differentiation (CD) system is commonly used as cell markers in immunophynotyping. Different kinds of cells in the immune system can be identified through the surface CD molecules which associating with the immune function of the cell. There are more than 320 CD unique clusters and subclusters have been identified. Some of the CD molecules serve as receptors or ligands important to the cell through initiating a signal cascade which then alter the behavior of the cell. Some CD proteins do not take part in cell signal process but have other functions such as cell adhesion. Protein tyrosine phosphatase, receptor type C (CD45), also known as PTPRC is a member of the protein tyrosine phosphatase (PTP) family which is known for its function to serve as signaling molecules and to regulate a variety of cellular processes such as cell proliferation, differentiation, mitotic cycle and oncogenic transformation. CD45 is found expression specifically in hemotopietic cells. CD45 consists of an extracellular domain, a single transmembrane segment and two tandem intracytoplasmic catalytic domains. It serves as an essential regulator of T-cell and B-cell antigen receptor signaling through either direct interaction with components of the antigen receptor complexs or by activating various Src family kinases required for the antigen receptor signaling and it also can suppress JAK kinases. |
