Human 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 NT-1/ BSF-3. CT-1 is a pleiotropic cytokine which 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. Biologically active human CT-1 is synthesized as a 201 amino acid polypeptide lacking a hydrophobic N-terminal secretion signal sequence.

Human and mouse CT-1 share 80% aa sequence identity and exhibit cross-species activity.

Protein Details

>95% by SDS-PAGE and analyzed by silver stain.
Endotoxin Level
<0.01 EU/µg as determined by the LAL method
Biological Activity
The biological activity of Human CT-1 was determined in a cell proliferation assay using a factor-dependent human erythroleukemic cell line, TF-1 (Kitamura, T. et al., 1989, J. Cell Physiol. 140:323). The expected ED50 is typically 1 - 4 ng/ml.
