Product Overview

Recombinant Cynomolgus/Rhesus macaque CD47 protein(AA Gln 19-Glu 141)(Accession # F7A802-1) is expressed from human 293 cells (HEK293). In the region Gln 19-Glu 141, the AA sequence of Cynomolgus and Rhesus macaque CD47 are homologus. This protein carries a polyhistidine tag at the C-terminus.

Expression System

HEK293

Species

Cynomolgus/Rhesus macaque

Tag

C-His Tag

Form

Lyophilized from sterile PBS, pH7.4, 10% trehalose.

Molecular Mass

This protein carries a polyhistidine tag at the C-terminus. The protein has a calculated MW of 15.8 kDa. The protein migrates as 30-50 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.

Protein length

Gln 19-Glu 141

Endotoxin

Less than 1.0 EU per ug by the LAL method.

Purity

>95% as determined by SDS-PAGE.

Storage

For long term storage, the product should be stored at lyophilized state at -20°C or lower. Please avoid repeated freeze-thaw cycles. This product is stable after storage at: -20°C to -70°C for 12 months in lyophilized state; -70°C for 3 months under sterile conditions after reconstitution.

Reconstitution

It is recommended that sterile water be added to the vial to prepare a stock solution of 0.2 mg/ml. Centrifuge the vial at 4ºC before opening to recover the entire contents.

SDS-PAGE

Cynomolgus/Rhesus macaque CD47, His Tag on SDS-PAGE under reducing (R) condition. The gel was stained overnight with Coomassie Blue. The purity of the protein is greater than 95%.
