Active Recombinant Human SIRPA Protein, Fc-tagged, PE-Labeled

• Cat.No.: SIRPA-4672H
• Product Overview: PE-Labeled Recombinant Human Protein(Glu 31 - Arg 370), fused with Fc tag, was expressed in HEK293.

Specification

• Source: HEK293
• Species: Human
• Tag: Fc
• Form: Lyophilized from 0.22 μm filtered solution in PBS, 0.5% BSA, pH7.4. Normally trehalose is added as protectant before lyophilization.
• Bio-activity: Flow Cytometry assay shows that PE-Labeled Human SIRP alpha, Fc Tag can bind to Jurkat cells overexpressing human CD47. 1 μL stock solution per million cells.FACS analysis shows that the binding of PE-Labeled Human SIRP alpha, Fc Tag to Jurkat cells overexpressing CD47 was inhibited by increasing concentration of neutralizing anti-human CD47 antibody. The IC50 is 0.37 μg/mL.
• Molecular Mass: This protein carries a human IgG1 Fc tag at the C-terminus.The protein has a calculated MW of 65.7 kDa.
• Protein Length: Glu 31 - Arg 370
• Storage: For long term, the product should be stored at lyophilized state at -20°C or lower.Please protect from light and avoid repeated freeze-thaw cycles. This product is stable after at:
  -20°C to -70°C for 12 months in lyophilized state; -70°C for 3 months under sterile conditions after reconstitution.
• Reconstitution: It is recommended that sterile water be added to the vial to prepare a stock solution of 0.2 ug/ul. Centrifuge the vial at 4°C before opening to recover the entire contents.
