TSLPR (Gly25-Lys231)_x000D_
Accession # Q9HC73-1 |
His |
| N-term |
C-term |
|
| Purity |
> 95% as determined by BisTris PAGE
> 95% as determined by HPLC |
| Endotoxin Level |
Less than 1EU per μg by the LAL method. |
| Biological Activity |
Measured by its binding ability in a functional ELISA. Immobilized Human TSLP, hFc Tag at 5μg/ml (100μl/Well) on the plate can bind TSLPR, His, Human. Test result was comparable to standard batch. |
| Expression System |
HEK293 |
| Theoretical Molecular Weight |
25.1 kDa |
| Apparent Molecular Weight |
Due to glycosylation, the protein migrates to 40-50 kDa based on Bis-Tris PAGE result. |
| Formulation |
Lyophilized from 0.22μm filtered solution in PBS (pH 7.4). |
| Reconstitution |
Centrifuge the tube before opening. Reconstituting to a concentration more than 100 μg/ml is recommended. Dissolve the lyophilized protein in distilled water. |
| Storage & Stability |
Upon receiving, the product remains stable up to 6 months at -20 °C or below. Upon reconstitution, the product should be stable for 3 months at -80 °C. Avoid repeated freeze-thaw cycles. |
| Target Background |
TSLP is an epithelial cell-derived cytokine synthesized in response to various stimuli, including protease allergens and microorganisms like viruses and bacteria. Biological functions of TSLP require heterodimer formation between the TSLP receptor (TSLPR) and IL-7 receptor-α, which polarize dendritic cells to induce type 2 inflammation and directly expand and/or activate Th2 cells, group 2 innate lymphoid cells, basophils, and other immune cells. |
| Synonyms |
