Protein Description: | High quality, high purity and low endotoxin recombinant Biotinylated Recombinant Human SIRP-alpha/CD172a Protein (RPCB0127), tested reactivity in HEK293 cells and has been validated in SDS-PAGE.100% guaranteed. |
Endotoxin: | < 1 EU/μg of the protein by LAL method. |
Purity: | ≥ 95 % as determined by Tris-Bis PAGE;≥ 95 % as determined by HPLC. |
Formulation: | Lyophilized from a 0.22 μm filtered solution of PBS, pH 7.4. Normally 8% trehalose is added as protectant before lyophilization. Contact us for customized product form or formulation. |
Reconstitution: | Centrifuge the tube before opening. Reconstitute to a concentration of 0.1-0.5 mg/mL in sterile distilled water. Avoid vortex or vigorously pipetting the protein. For long term storage, it is recommended to add a carrier protein or stablizer (e.g. 0.1% BSA, 5% HSA, 10% FBS or 5% Trehalose), and aliquot the reconstituted protein solution to minimize free-thaw cycles. |
Storage: | Store at -20℃. Store the lyophilized protein at -20℃ to -80℃ up to 1 year from the date of receipt. After reconstitution, the protein solution is stable at -20℃ for 3 months, at 2-8℃ for up to 1 week. |
Signal regulatory protein α (SIRPα) is a regulatory membrane glycoprotein from SIRP family expressed mainly by myeloid cells and also by stem cells or neurons.SIRPα acts as inhibitory receptor and interacts with a broadly expressed transmembrane protein CD47 also called the "don′t eat me" signal.Cancer cells highly expressed CD47 that activate SIRP α and inhibit macrophage-mediated destruction.
