Active Recombinant Human ICOS protein(C136S,C137S), His-tagged, Low Endotoxin

• Cat.No.: ICOS-6754H
• Product Overview: Recombinant Human ICOS protein(Q9Y6W8-1)(Glu21-Phe141(C136S,C137S)), fused with C-terminal His tag, was expressed in HEK293.

Specification

• Species: Human
• Source: HEK293
• Tag: His
• Protein Length: 21-141 aa
• Form: Lyophilized from 0.22μm filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization.
• Bio-activity: Immobilized Human ICOS (C136S, C137S), His Tag at 5μg/ml (100μl/Well) on the plate. Dose response curve for Human B7-H2, hFc Tag with the EC50 of 5.0ng/ml determined by ELISA.
• Molecular Mass: The protein has a predicted MW of 14.8 kDa. Due to glycosylation, the protein migrates to 35-40 kDa based on Bis-Tris PAGE result.
• Endotoxin: Less than 0.01 EU per μg by the LAL method.
• Purity: > 95% as determined by Bis-Tris PAGE
• Storage: Store at -20 to -80°C for 24 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.
• Reconstitution: Dissolve the lyophilized protein in distilled water.
