Cat#:CD28-169MAC;Product Name:Recombinant Mouse CD28 Protein;Synonym:CD28,Tp44;Description:Mouse CD28 Protein, Asn 20 - Lys 149 was produced in HEK293 cells.;Source:HEK293;Predicted N Terminal:Asn 20;Molecular Characterization:Recombinant mouse CD28 protein CD28 (Asn 20-Lys 149)NP_031668.3polyhistidineMouse CD28 with His Tag is fused with a polyhistidine tag at the C-terminus, and has a calculated molecular weight of 17 kDa. The predicted N-terminus is Asn 20. The reducing (R) protein migrates as 30-38 kDa in SDS-PAGE due to glycosylation.;Purity:Greater than 85% as determined by SDS-PAGE.;Endotoxin:<1.0 EU per μg of recombinant mouse CD28 protein by the LAL method.;Formulation:Recombinant mouse CD28 protein was lyophilized from 0.22 μm filtered solution in PBS, pH7.4.;Stability:Recombinant mouse CD28 protein was stable up to 1 year from date of receipt at -70℃;Storage:Store recombinant mouse CD28 protein under sterile conditions at -20℃ to -80℃. It is recommended that the recombinant protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles.;Usage:For Lab Research Use Only;
