Background
2B4 (CD244) is expressed by memory-phenotype CD8() T cells and all natural killer (NK) cells. The ligand for 2B4, CD48, is expressed on hematopoietic cells. 2B4 is conserved in humans and mice, and a number of reports have linked 2B4 with activation of lymphocytes.Engagement of 2B4 on NK cell surfaces with specific antibodies or CD48 can trigger cell mediated cytotoxicity, interferon ? secretion, phosphoinositol turnover and NK cell invasiveness.
Description
Recombinant Human 2B4/CD244/SLAMF4 Protein is expressed from Expi293 with hFc tag at the C-terminal. It contains Cys22-Arg221.
Target
2B4/CD244/SLAMF4
Species
Human
Gene/Protein ID
Q9BZW8-2
Exact Sequence
Cys22-Arg221
Molecular Weight
The protein has a predicted MW of 49 kDa. Due to glycosylation, the protein migrates to 68-75 kDa based on the Tris-Bis PAGE result.
Activity
Immobilized Human CD48, His Tag at 1ug/ml (100ul/well) on the plate. Dose response curve for Human 2B4, hFc Tag with the EC50 of 0.45ug/ml determined by ELISA. See testing image for detail.
Tag
C-hFc
Express System
Expi293
Purity
> 95% as determined by Tris-Bis PAGE; > 95% as determined by HPLC
Endotoxin
Less than 1EU per ug by the LAL method.
Formulation
Lyophilized from 0.22 um filtered solution in PBS (pH 7.4). Normally 5% trehalose is added as a protectant before lyophilization.
Stability and Storage

Reconstituted protein stable at -80 C for 12 months, 4 C for 1 week. Use a manual defrost freezer and avoid repeated freeze-thaw cycles.

Shipping
Shipped at ambient temperature.
Reconstitution

Centrifuge tubes before opening. Reconstituting to a concentration of more than 100 ug/ml is recommended. Dissolve the lyophilized protein in distilled water.
