Product Description

Cat

IMP-10265

Official Symbol

CD22

Product Overview

Recombinant human Siglec-2/CD22 protein (Asp20-Arg687) with a Human IgG1 (Pro100-Lys330) Fc tag at C-terminus was expressed in Mouse myeloma cell line.

Description

Predicted to enable CD4 receptor binding activity; protein phosphatase binding activity; and sialic acid binding activity. Involved in B cell activation; negative regulation of B cell receptor signaling pathway; and regulation of endocytosis. Located in early endosome and recycling endosome.

Expression System

Mouse myeloma cell line

Species

Human

Tag

C-hFc

Predicted N Terminal

Asp20

Form

Lyophilized from a 0.2 μm filtered solution in PBS.

Molecular Mass

Predicted Molecular Mass: 101.9 kDa (monomer)
SDS-PAGE: 122-127 kDa, reducing conditions

Protein length

Asp20-Arg687

Bio-activity

Measured by the ability of the immobilized protein to support the adhesion of human red blood cells. The ED50 for this effect is 0.03-0.15 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

Storage
