Cardiotrophin-1 Recombinant Protein

CT-1 is a member of the IL-6 family of cytokines which also includes LIF, CNTF, OSM (Oncostatin M), IL-11, IL-6 and possibly NNT-1/ BCSF-3. CT-1 is a pleiotropic cytokine which is expressed in various tissues including the adult heart, skeletal muscle, ovary, colon, prostate and fetal lung and signals through the LIF receptor and the gp130 receptor subunit. CT-1 has the ability to induce cardiac myocyte hypertrophy, and enhances the survival of cardiomyocyte and different neuronal populations. Recombinant murine Cardiotrophin-1 is a 21.3 kDa protein consisting of 202 amino acid residues.

The lyophilized Cardiotrophin-1 recombinant protein is stable for at least 2 years from date of receipt at -20˚ C. Reconstituted Cardiotrophin-1 is stable for at least 3 months when stored in working aliquots with a carrier protein at -20˚ C. As with any protein, exposing Cardiotrophin-1 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.
