CRH Human (146-196)

CRF, Corticotropin-Releasing Factor.

The CRHHuman is created as a recombinant protein with a 4kda N-terminal fusion of His Tag. The CRHHis-Tagged Fusion Protein, produced in E. coli, is a 10kDa protein containing 51 amino acid residues of the CRHHuman, 146-196 amino acids.

Escherichia Coli.

Filtered White lyophilized (freeze-dried) powder.

Each mg was lyophilized with 1xPBS, 0.4% SDS and 4mM DTT.

It is recommended to add deionized water to prepare a working stock solution of approximately 0.5mg/ml and let the lyophilized pellet dissolve completely. Product is not sterile! Please filter the product by an appropriate sterile filter before using it on cell culture.

Store lyophilized CRH at -20°C. Aliquot the product after reconstitution to avoid repeated freezing/thawing cycles. Reconstituted protein can be stored at 4°C for a limited period of time; it does not show any change after two weeks at 4°C.

Greater than 90% as determined by SDS-PAGE.

CRH is a neuropeptide which regulates body's response to stress. CRH takes part in the hypothalamic-pituitary-adrenal axis which controls the production of cortisol and other glucocorticoids. CRH is synthesized in different tissues such as the brainstem, hypothalamus and peripheral organs. In Pregnancy, CRH regulates parturition and fetal development. CRH binds 2 types of receptors- CRH receptor 1 and CRH receptor 2, both are G-protein-coupled receptors (GPCRs). After binding CRHR1, CRH initiates a cascade of intracellular signalling which leads to the release of ACTH from the anterior pituitary. This release stimulates cortisol secretion from the adrenal glands, which is necessary for controlling the body's stress response and maintain energy balance and immune function.
