表达区间及表达系统(Source)

Human HLA-E*01:03&B2M&Peptide (VMAPRTLVL) Tetramer Protein is expressed from HEK293 with His tag and Avi tag at the C-Terminus,tetramer is assembled by biotinylated monomer and streptavidin. It contains Gly25-Ile305(HLA-E*01:03), Ile21-Met119(B2M) and VMAPRTLVL peptide.[Accession | P13747(HLA-E*01:03)&P61769(B2M)&VMAPRTLVL]

分子量大小(Molecular Weight)

The protein has a predicted MW of 258 kDa. Due to glycosylation, the protein migrates to 260-265 kDa under Non reducing (N) condition based on SDS-PAGE result.

内毒素(Endotoxin)

Less than 1EU per μg by the LAL method.

纯度(Purity)

> 95% as determined by SDS-PAGE and HPLC.

活性(Activity)

SPR Data:Human NKG2A&CD94, mFc Tag captured on CM5 Chip via anti-mouse antibody can bind Human HLA-E*01:03&B2M&Peptide (VMAPRTLVL) Tetramer, His Tag with an affinity constant of 17.61 nM as determined in SPR assay .Human NKG2C&CD94, His Tag immobilized on CM5 Chip can bind Human HLA-E*01:03&B2M&Peptide (VMAPRTLVL) Tetramer, His Tag with an affinity constant of 1.65 μM as determined in SPR assay .

制剂(Formulation)

Lyophilized from 0.22μm filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization.

重构方法(Reconstitution)

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

 

储存条件

1.The product should be stored at -25~-15℃ for 1 year from date of receipt.

2.2-7 days, 2 ~ 8 °C under sterile conditions after reconstitution.

3.3 -6 months, -85~-65℃ under sterile conditions after reconstitution.

4.Recommend to aliquot the protein into smaller quantities when first used and avoid repeated freeze-thaw cycles.

 

注意事项

1.Please operate with lab coats and disposable gloves,for your safety.

2.This product is for research use only.
