Name : Biotinylated Human TSLP Protein

Product Source :
Recombinant Biotinylated Human TSLP Protein is expressed from HEK293 with His tag and Avi tag at the C-Terminus. It contains Tyr29-Gln159.[Accession | Q969D9-1]

Molecular Weight :
The protein has a predicted MW of 17.8 kDa. Due to glycosylation, the protein migrates to 12 kDa&25-30 kDa based on Tris-Bis PAGE result.

Endotoxin Level :
Less than 1EU per μg by the LAL method.

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

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

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 and Stability :
-20 to -80°C for 12 months as supplied from date of receipt. -80°C for 3-6 months after reconstitution. 2-8°C for 2-7 days after reconstitution. Recommend to aliquot the protein into smaller quantities for optimal storage. Please minimize freeze-thaw cycles.

Product Concentration :
Tris-Bis PAGE Biotinylated Human TSLP on Tris-Bis PAGE under reduced conditions. The purity is greater than 95%. SEC-HPLC The purity of Biotinylated Human TSLP is greater than 95% as determined by SEC-HPLC. ELISA Data Immobilized Anti-TSLP Antibody, hFc Tag at 0.5μg/ml (100μl/well) on the plate. Dose response curve for Biotinylated Human TSLP, His Tag with the EC50 of 1.6ng/ml determined by ELISA.

Background :
Thymic Stromal Lymphopoietin (TSLP) was originally identified as an activity from the conditioned medium of a mouse thymic stromal cell line that promoted the development of B cells. Cytokine that induces the release of T-cell-attracting chemokines from monocytes and, in particular, enhances the maturation of CD11c dendritic cells. Can induce allergic inflammation by directly activating mast cells.

Synonyms :
thymic stromal lymphopoietin; TSLP
