Biological Activity
Description
PTPRC/CD45RABC Protein, Human (HEK293, His) is a type 1 transmembrane protein tyrosine phosphatase (PTPase) expressed by all the haematopoietic stem cells (HSCs) except that of erythrocytes and platelets.
Background
The leucocyte common antigen, protein tyrosine phosphatase receptor type C (PTPRC), also known as CD45, is a transmembrane glycoprotein, expressed on almost all haematopoietic cells except for mature erythrocytes, and is an essential regulator of T and B cell antigen receptor-mediated activation. CD45 is composed of two cytoplasmic domains, a transmembrane domain and an extracellular domain. Disruption of the equilibrium between protein tyrosine kinase and phosphatase activity (from CD45 and others) can result in immunodeficiency, autoimmunity, or malignancy. CD45 is normally present on the cell surface, therefore it works upstream of a large signalling network which differs between cell types, and thus the effects of CD45 on these cells are also different[1].
Verified Bioactivity
Measured by its ability to inhibit the proliferation of M-NFS-60 Mice myeloid leukemia lymphocytes. The ED50 this effect is ≤2.406 μg/mL, corresponding to a specific activity is ≥415.62 units/mg.

Product Properties
Lyophilized powder.
1.Lyophilized from a 0.22 μm filtered solution of PBS, pH 7.4.
2.Lyophilized from a 0.22 μm filtered solution of 20 mM PB, 150 mM NaCl, pH 7.4.

Please refer to the lot-specific COA for specific buffer information.
Note: For SPR assay, please replace the buffer. Primary amine components (e.g., Tris, imidazole) can affect protein-coupled chips.
<1 EU/μg, determined by LAL method.
It is not recommended to reconstitute to a concentration less than 100 μg/mL in ddH2O. For long term storage it is recommended to add a carrier protein (0.1% BSA, 5% HSA, 10% FBS or 5% Trehalose).
Stored at -20°C for 2 years from date of receipt. After reconstitution, it is stable at 4°C for 1 week or -20°C for longer (with carrier protein). It is recommended to freeze aliquots at -20°C or -80°C for extended storage.
Room temperature in continental US; may vary elsewhere.
