Recombinant Human SIRPA Protein, His-tagged, Alexa Fluor 647 conjugated

• Cat.No.: SIRPA-3218HAF647
• Product Overview: Alexa Fluor 647 conjugated recombinant human SIRPA (NP_542970.1) extracellular domain (Met 1-Arg 370), fused with a polyhistidine tag at the C-terminus, was produced in Human Cell.

Specification

• Species: Human
• Source: HEK293
• Tag: His
• Protein Length: 351
• Form: Lyophilized
• Molecular Mass: The recombinant human SIRPA consists of 351 amino acids and predictes a molecular mass of 39 kDa. In SDS-PAGE under reducing conditions, the apparent molecular mass of rhSIRPA is approximately 45-50 kDa due to glycosylation.
• Endotoxin: < 1.0 EU/ μg of the protein as determined by the LAL method.
• Characteristic: Disulfide-linked homodimer
  Labeled with Alexa Fluor 647 via amines
  Excitation = 650 nm
  Emission = 668 nm
• Stability: Samples are stable for up to 12 months from date of receipt at -70 centigrade.
• Storage: Store it under sterile conditions at -20 to -70 centigrade. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles.
• Storage Buffer: Lyophilized from sterile PBS, pH 7.4
• Reconstitution: It is recommended that sterile water be added to the vial to prepare a stock solution. Centrifuge the vial at 4 centigrade before opening to recover the entire contents.
• Conjugation: Alexa Fluor 647
