Human ULBP-2 Protein

产品信息(Product Info)
表达区间及表达系统(Source)

Recombinant Human ULBP-2 Protein is expressed from HEK293 with hFc (IgG1) tag at the C-Terminus.
It contains Gly26-Ser216 [Accession | Q9BZM5].

分子量大小(Molecular Weight)

The protein has a predicted MW of 48.40 kDa. Due to glycosylation, the protein migrates to 55-65 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 1 EU 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)

Dissolve the lyophilized protein in distilled water. Please refer to the Certificate of Analysis for detailed instructions.

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.

BLI Data
Loaded Human ULBP-2, hFc Tag on ProA-Biosensor can bind Human NKG2D, His Tag (Cat. NKG-HM42D) with an affinity constant of 1.16 µM as determined in BLI assay (Gator® Prime). (QC Test)
SPR Data
Human ULBP-2, hFc Tag captured on CM5 Chip via Protein A can bind Human NKG2D, His Tag (Cat. NKG-HM42D) with an affinity constant of 62.42 nM as determined in SPR assay (Biacore T200).
背景(Background)

ULBPs activate multiple signaling pathways in primary NK cells, resulting in the production of cytokines and chemokines. Binding of ULBPs ligands to NKG2D induces calcium mobilization and activation of the JAK2, STAT5, ERK and PI3K kinase/Akt signal transduction pathway, mediating natural killer cell cytotoxicity.

分子别名(Synonyms)

ALCAN-alpha; N2DL2; NKG2DL2; RAET1H; RAET1L; ULBP2; ULBP-2/5/6; NKG2D ligand 2

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