Storage Conditions: The lyophilized TSLP recombinant protein is stable for at least 2 years from date of receipt at -20°C. Reconstituted TSLP is stable for at least 3 months when stored in working aliquots with a carrier protein at -20°C. As with any protein, exposing TSLP recombinant protein to repeated freeze / thaw cycles is not recommended. When working with proteins care should be taken to keep recombinant protein at a cool and stable temperature.
Additional Information:
TSLP is a hemopoietic protein that is expressed in the heart, liver and prostate. TSLP overlaps biological activities with IL-7 and binds with the heterodimeric receptor complex consisting of the IL-7R alpha chain (IL-7Rand#945;) and the TSLP-specific chain (TSLPR). Like IL-7, TSLP induces phosphorylation of STAT3 and STAT5, but uses kinases other than the JAKs for activation. TSLP prohibited apoptosis and stimulated growth of the human acute myeloid leukemia (AML)-derived cell line MUTZ3. It induces the release of T cell-attracting chemokines TARC and MDC from monocytes and activates CD11c(+) dendritic cells (DCs). TSLP activated DCs primed naïve T cells to produce the proallergic cytokines (IL-4, IL-5, IL-13, TNFand#945) while down-regulating IL-10 and IFN-? suggesting a role in initiating allergic inflammation. Recombinant human TSLP is a 15.0 kDa protein consisting of 132 amino acid residues.
