Purity

Greater than 95% as determined by reducing SDS-PAGE.

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.
Appearance

Lyophilized powder.

Formulation

Lyophilized from a 0.2 μm filtered solution of PBS, pH 7.4.

Endotoxin Level

<1 EU/μg, determined by LAL method.

Reconstitution

It is not recommended to reconstitute to a concentration less than 100 μg/mL in ddH2O.

Storage & Stability

Stored at -20°C. After reconstitution, it is stable at 4°C for 1 week or -20°C for longer. It is recommended to freeze aliquots at -20°C or -80°C for extended storage.

Shipping

Room temperature in continental US;may vary elsewhere.

Background

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