This recombinant protein contains Glu31-Arg370 of UniProt P78324. It has a His tag at the C-terminus. The protein's calculated molecular weight is 38.5 kDa, migrating at 47-55 kDa in reducing SDS-PAGE due to glycosylation.
gene name SIRPA
gene id UniProt P78324
host species Human
production host HEK293
tags C-9xHis
purity > 95% as determined by SDS-PAGE
endotoxin No endotoxin was detected in final prodcut using LAL method to the method's sensitivity level (< 1.0 EU/ug).
formulation Protein was lyophilized from a solution in PBS, pH7.4, with trehalose added as protectant.
reconstitution Reconstitute lyophilized powder with water to a concentration of no less than 100 ug/ml, solubilize at RT for 30 min with occasional gentle mixing. It is recommended that 0.1% of HSA be added as a carrier protein for long term storage.
shipping Shipped at ambient conditions
storage Lyophilized form is stable for 2 weeks at room temperature or for 12 months at 4-8°C. Keep at -20°C or lower for long term storage. After reconstitution, store at 4°C for 2-7 days or at below -20°C for up to 3 months.
