Biological Activity

Description

Calcitonin Protein, Human (HEK293, His), a recombinant human Calcitonin produced in HEK293 cells, has a His tag at the C-terminus. Calcitonin has an effect on decreasing osteoclast activity and has the potential for hypercalcemia research[1].

Background

Calcitonin is a 32 amino acid hormone secreted by the C-cells of the thyroid gland. Calcitonin secretion is stimulated by increases in the serum calcium concentration and calcitonin protects against the development of hypercalcemia. Calcitonin is also stimulated by gastrointestinal hormones such as gastrin[1].

Product Properties

Appearance

Lyophilized powder.

Formulation

Lyophilized after extensive dialysis against 20 mM PB, 150 mM NaCl, pH 7.4.

Endotoxin Level

<1 EU/μg, determined by LAL method.

Reconstitution

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).

Storage & Stability

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.

Shipping

Room temperature in continental US; may vary elsewhere.
