Human CD161 Protein

产品信息(Product Info)
表达区间及表达系统(Source)

Recombinant Human CD161 Protein is expressed from HEK293 with His tag at the C-Terminus.
It contains Gln67-Ser225 [Accession | Q12918-1].

分子量大小(Molecular Weight)

The protein has a predicted MW of 19.6 kDa. Due to glycosylation, the protein migrates to 38-45 kDa based on Bis-Tris PAGE result.

纯度(Purity)

> 95% as determined by Bis-Tris PAGE
> 95% as determined by HPLC

内毒素(Endotoxin)

Less than 1EU per μg by the LAL method.

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.

存储(Storage)

-20 to -80°C for 12 months as supplied from date of receipt.
-80°C for 3 months after reconstitution.
Recommend to aliquot the protein into smaller quantities for optimal storage. Please minimize freeze-thaw cycles.

产品数据(Assay Data)
Bis-Tris PAGE

Human CD161 on Bis-Tris PAGE under reduced condition. The purity is greater than 95%.

SEC-HPLC

The purity of Human CD161 is greater than 95% as determined by SEC-HPLC.

ELISA Data

Immobilized Human CD161, His Tag at 2μg/ml (100μl/Well) on the plate. Dose response curve for Anti-CD161 Antibody, hFc Tag with the EC50 of 5.3ng/ml determined by ELISA (QC Test).

SPR Data

Anti-CD161 Antibody, hFc tag captured on CM5 Chip via Anti-hFc IgG can bind Human CD161, His Tag with an affinity constant of 78.8 nM as determined in SPR assay (Biacore T200).

背景(Background)

CD161 (NKRP1) is a lectin-like receptor present on NK cells and rare T-cell subsets. We have observed CD161 expression in some cases of T-cell prolymphocytic leukemia (T-PLL) and found it to be useful in follow-up and detection of disease after treatment.

Note: HPLC results always come from liquid protein, due to absorption peak interference of trehalose in lyophilized powder.
