Relevance
Isoform 1 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. Isoform 2 May act as an antimicrobial peptide in the oral cavity and on the skin.
Endotoxin
Less than 1.0 EU/μg as determined by LAL method.
Purity
Greater than 95% as determined by SDS-PAGE.
Activity
Yes
Bioactivity
Measured by its binding ability in a functional ELISA. Immobilized human TSLP (R127A, R130A) at 2 μg/mL can bind Anti-TSLP recombinant antibody (CSB-RA025141MA2HU) . The EC50 is 52.55-58.67 ng/mL.
Form
Lyophilized powder
Buffer
Lyophilized from a 0.2 μm sterile filtered PBS, 6% Trehalose, pH 7.4
Reconstitution
We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Please reconstitute protein in deionized sterile water to a concentration of 0.1-1.0 mg/mL.We recommend to add 5-50% of glycerol (final concentration) and aliquot for long-term storage at -20°C/-80°C. Our default final concentration of glycerol is 50%. Customers could use it as reference.
Molecular Weight
16.6 kDa

Storage Conditions
The shelf life is related to many factors, storage state, buffer ingredients, storage temperature and the stability of the protein itself. Generally, the shelf life of liquid form is 6 months at -20°C/-80°C. The shelf life of lyophilized form is 12 months at -20°C/-80°C.
