IMP-112

Official Symbol

ICOS

Product Overview

Recombinant Human ICOS protein(AA Glu 21-Phe 141)(Accession # Q9Y6W8-1) is expressed from human 293 cells (HEK293). This protein carries a human IgG1 Fc tag at the C-terminus.

Expression System

HEK293

Species

Human

Tag

C-Fc Tag

Form

Lyophilized from sterile Tris with Glycine, Arginine and NaCl, pH7.5, 10% trehalose.

Molecular Mass

This protein carries a human IgG1 Fc tag at the C-terminus. The protein has a calculated MW of 40.2 kDa. The protein migrates as 46-55 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.

Protein length

Glu 21-Phe 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

Human ICOS, Fc 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%.

Bioactivity-ELISA 1

Immobilized Human B7-H2, His Tag at 1 ug/mL (100 uL/well) can bind Human ICOS, Fc Tag with a linear range of 0.4-6 ng/mL.
