Recombinant Human CD244 Protein (Cys22-Ile228), C-hFc and Avi-tagged, Biotinylated
Product Description
Cat
IMP-10280
Official Symbol
CD244
Product Overview
Biotinylated recombinant human 2B4/CD244/SLAMF4 protein (Cys22-Ile228) with a Human IgG1 (Pro100-Lys330) Fc tag and Avi tag at C-terminus was expressed in Chinese Hamster Ovary cell line.
Description
This gene encodes a cell surface receptor expressed on natural killer (NK) cells (and some T cells) that mediate non-major histocompatibility complex (MHC) restricted killing. The interaction between NK-cell and target cells via this receptor is thought to modulate NK-cell cytolytic activity. Alternatively spliced transcript variants encoding different isoforms have been found for this gene.

Bio-activity
Measured by its binding ability in a functional ELISA. When Recombinant Human CD48/SLAMF2 Fc Chimera Protein is immobilized at 1.0 μg/mL, 100 μL/well, the concentration of Biotinylated Recombinant Human 2B4/CD244/SLAMF4 Fc Chimera Avi-tag that produces 50% of the optimal binding response is 35.0-350 ng/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
Storage
