Recombinant Human SIRPA protein, His-Avi-tagged

• Cat.No.: SIRPA-324H
• Product Overview: Recombinant human Sirpa V8 Protein is expressed from mammalian with a His Tag and Avi Tag at the C-terminal. It contains Glu31-Arg369.

Specification

• Species: Human
• Source: HEK293
• Tag: Avi&His
• Protein Length: Glu31-Arg369
• Description: 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 macrophagemediated destruction.
• Form: Supplied as 0.22um filtered solution in PBS (pH 7.4).
• Molecular Mass: The protein has a predicted MW of 40.1 kDa.Due to glycosylation, the protein migrates to 52-68 KDa based on Bis-Tris PAGE result.
• Endotoxin: Less than 0.05 EU per ug by the LAL method.
• Purity: > 95% as determined by Bis-Tris PAGE; > 95% as determined by HPLC
• Storage: The product should be stored at -70°C. Please do not repeated freeze-thaw cycles.
