Cardiotrophin-1/CTF1 Protein, Human (CHO)

Cardiotrophin-1/CTF1 Protein, Human (CHO), a member of IL-6 family of cytokines, is a key regulator of energy homeostasis and of glucose and lipid metabolism.

Cardiotrophin (CT)-1 belongs to the IL-6 family of cytokines^[1]. Cardiotrophin-1 (CT1) plays an important role in the differentiation, development, and survival of neural stem cells. CT1 plays a key role in neural tissue development and has survival-promoting, anti-apoptotic effects in neural injury or death. CT1 induces a phenotypic switch in sympathetic neurons and promotes the survival of dopaminergic neurons from the central nervous system and ciliary neurons from the periphery^[2].

The ED₅₀ is <0.4 ng/mL as measured by TF-1 cells.

  ≥ 95%, as determined by reducing SDS-PAGE.

Lyophilized powder.

Lyophilized from a 0.22 μm filtered solution of PBS.

<0.2 EU/μg, determined by LAL method.

It is not recommended to reconstitute to a concentration less than 100 μg/mL in ddH₂O. For long term storage it is recommended to add a carrier protein (0.1% BSA, 5% HSA, 10% FBS or 5% Trehalose).

Stored at -20°C for 2 years from date of receipt. After reconstitution, it is stable at 4°C for 1 week or -20°C for longer (with carrier protein). It is recommended to freeze aliquots at -20°C or -80°C for extended storage.

Room temperature in continental US; may vary elsewhere.
