Recombinant Mouse SEMA3A Protein,His Tag

Description :
Synonyms Semaphorin;Sema III; Sema D Source Mouse SEMA3A Protein is expressed from HEK293 with His tag at the N-Terminus. It contains Tyr21-Val772.[Accession | O08665] Molecular Weight The protein has a predicted MW of 86.6 kDa same as SDS-PAGE result. 内毒素Endotoxin Less than 1EU per g by the LAL method. Purity > 95% as determined by SDS-PAGE and HPLC. Formulation Lyophilized from 0.22m filtered solution in 20mM Tris, 150mM NaCl, 100mM L-arginine, 100mM glutamic acid (pH 8.5). Normally 8% trehalose is added as protectant before lyophilization. Reconstitution Centrifuge the tube before opening. Reconstituting to a concentration more than 100 g/ml is recommended. Dissolve the lyophilized protein in distilled water.
