Description

SIRP alpha/CD172a Protein, Human (CAA71403.1, HEK 293, His) , as a recombinant protein produced in HEK293 cells, is a polypeptide chain with a His tag.

Background

SIRPA is a specific cell-surface marker for isolating cardiomyocytes derived from human pluripotent stem cells[1].

Biological Activity
2 μg/mL (100 μL/well) of immobilized Human CD47 –Fc can bind Human SIRPA -His with an ED50 value of 0.49 μg/mL, corresponding to an affinity constant of 10.1 nM.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.

  • Specific Active Calculator

The reconstitution calculator equation

Volume (to add to vial) = Mass (in vial) ÷ Desired Reconstitution Concentration

Volume (to add to vial) = Mass (in vial) ÷ Desired Reconstitution Concentration
= ÷

The dilution calculator equation

Concentration (start) × Volume (start) = Concentration (final) × Volume (final)

This equation is commonly abbreviated as: C1V1 = C2V2

Concentration (start) × Volume (start) = Concentration (final) × Volume (final)
× = ×
C1   V1   C2   V2

The specific active calculator equation

Specific Active (Unit/mg) = 106 ÷ Biological Activity (ED50)

Specific Active (Unit/mg) = 106 ÷ Biological Activity (ED50)
Unit/mg = 106 ÷ ng/mL
