Cynomolgus SIRP alpha/CD172a Protein (SRP-CM172) Summary

Product Description

 Recombinant Cynomolgus SIRP alpha/CD172a Protein is expressed from HEK293 with His tag at the C-Terminus.It contains Glu31-Arg370.

Product Background

 Signal regulatory protein α (SIRPα) is a regulatory membrane glycoprotein from SIRP family expressed mainly by myeloid cells and also by stem cells or neurons.SIRPα acts as inhibitory receptor and interacts with a broadly expressed transmembrane protein CD47 also called the "don´t eat me" signal.Cancer cells highly expressed CD47 that activate SIRP α and inhibit macrophage-mediated destruction.

Shipping, Reconstitution, & Storage

Form
 Lyophilized
Shipping
 Shipped at ambient temperature.
Formulation
 Lyophilized from 0.22um filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization.
Reconstitution
 Dissolve the lyophilized protein in distilled water. It is recommended to resuspend at 0.5 mg/mL if the lyophilized powder is 100 ug or less, at 1mg/ml for 500ug or 1mg lyophilized powder. Do not mix by vortex or vigorous shaking.
Stability And Storage
 -20 to -80°C for 12 months as supplied from date of receipt.；-80°C for 3 months after reconstitution.；Recommend to aliquot the protein into smaller quantities for optimal storage. Please minimize freeze-thaw cycles.
