Recombinant Human Cardiotrophin-1 (CT-1)

Cardiotrophin-1 is a pleiotrophic cytokine and is a member of the IL-6 cytokine family that also includes IL6, IL11, LIF, OSM, CLC and IL31.Full length human CT-1 shares a 79% amino acid sequence identity with murinic CT-1 and both lack a canonical signal sequence. Cardiotrophin-1 interacts with the leukemia inhibitory factor receptor (LIFR) heterodimer and the glycoprotein 130 subunit (gp130) and has the ability to induce cardiac myocyte hypertrophy. It is highly expressed in various skeletal muscles and cardiac tissue, as well as the colon, ovary and prostate, liver, and pancreas, while lower expression levels are found in the lungs, kidney, pancreas, testis, and small intestine.

Source

E. coli

Concentration

<1.0 EU/μg of recombinant protein as determined by the LAL method

Purity

>95% as determined by SDS-PAGE

Solubility

Reconstitute in sterile 20mM Tris, pH 8.0 at 100µg/mL (containing at least 0.1% human or bovine serum albumin). Further dilutions should be made in aqueous buffers supplemented with carrier protein, such as 0.1–1.0% BSA.

Function

ED50 is ≤ 0.5 ng/mL as determined by the dose-dependent TF-1 cell proliferation.

Molecular Weight

Ambient Temperature

Storage Conditions

The lyophilized protein is stable for at least one year from date of receipt at -70°C. Upon reconstitution, this cytokine can be stored in working aliquots at 2° - 8°C for one month, or at -20°C for six months, with a carrier protein without detectable loss of activity. Avoid repeated freeze/thaw cycles.
