Recombinant Human CD80 Protein (Val35-Asn242), C-6×His and Avi-tagged

Product Description

Cat

IMP-10316

Official Symbol

CD80

Product Overview

Recombinant human B7-1/CD80 protein (Val35-Asn242) with 6×His tag and Avi-tag at C-terminus was expressed in Chinese Hamster Ovary cell line.

Description

The protein encoded by this gene is a membrane receptor that is activated by the binding of CD28 or CTLA-4. The activated protein induces T-cell proliferation and cytokine production. This protein can act as a receptor for adenovirus subgroup B and may play a role in lupus neuropathy.

Protein length

Val35-Asn242

Bio-activity

Measured by its binding ability in a functional ELISA. When Recombinant Human CTLA-4 Fc Chimera is immobilized at 1 μg/mL (100 μL/well), Biotinylated Recombinant Human B7-1/CD80 His-tag Avi-tag binds with an ED50 of 0.1-0.6 μg/mL.

Endotoxin

<0.10 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.
