Product Description

Cat

IMP-10607

Official Symbol

ICOSLG

Product Overview

Biotinylated recombinant human B7-H2 Isoform 3 protein (Ala19-Thr139) with a Human IgG1 (Pro100-Lys330) Fc tag and Avi-tag at C-terminus was expressed in Human embryonic kidney cell.

Description

Conjugate

Biotinylated

Molecular Mass

Predicted Molecular Mass: 42 kDa
SDS-PAGE: 61-70 kDa, under reducing conditions

Protein length

Ala19-Thr139

Bio-activity

Measured by its binding ability in a functional ELISA. When Recombinant Human ICOS Fc Chimera is immobilized at 10 μg/mL, 100 μL/well, the concentration of Biotinylated Recombinant B7-H2 Isoform 3 Fc Chimera Avi-tag that produces 50% of the optimal binding response is approximately 10-50 μg/mL.

Endotoxin

<1.0 EU/μg of the protein by the LAL method.

Purity

>95%, by SDS-PAGE visualized with Silver Staining and quantitative densitometry by Coomassie Blue Staining.

Notes

Disulfide-linked homodimer, biotinylated via Avi-tag
