Synthesized primarily by the pituitary gland, prolactin is a neuroendocrine hormone that functions to promote and maintain lactation and has also been shown to play a role in breast cancer development, regulation of reproductive function and immune-regulation. While Human prolactin shares only 60% and 63% amino acid sequence identity with mouse and rat prolactin, respectively, the human prolactin receptor can be activated by Rat PRL. abm's Recombinant Human PRL is a single, non-glycosylated polypeptide chain with a molecular mass of 23 kDa.

Description
It is recommended to reconstitute lyophilized PRL in sterile distilled water to no less than 100µg/ml, which can then be further diluted to other aqueous solutions.
Format
Lyophilized PowderLyophilized from a concentrated solution in PBS.
Purity
>95% as determined by SDS-PAGE
Storage
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.
