Name : Biotinylated Cynomolgus TSLP Protein (Primary Amine Labeling)
Product Source :
Recombinant Biotinylated Cynomolgus TSLP Protein (Primary Amine Labeling) is expressed from HEK293 with His tag at the C-Terminus. It contains Tyr29-Gln159.[Accession | A0A7N9CAT7]
Molecular Weight :
The protein has a predicted MW of 16.3 kDa. Due to glycosylation, the protein migrates to 10-13 kDa based on Tris-Bis PAGE result.
Endotoxin Level :
Less than 1EU per μg by the LAL method.
Purity :
> 90% as determined by Tris-Bis PAGE> 90% as determined by HPLC
Formulation :
Lyophilized from 0.22 μm 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 Cynomolgus TSLP on Tris-Bis PAGE under reduced conditions. The purity is greater than 90%. SEC-HPLC The purity of Biotinylated Cynomolgus TSLP is greater than 90% as determined by SEC-HPLC. ELISA Data Immobilized Biotinylated Cynomolgus TSLP, His Tag at 0.5μg/ml (100μl/well) on the streptavidin precoated plate (5μg/ml). Dose response curve for Anti-TSLP Antibody, hFc Tag with the EC50 of 11.2ng/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
