Description
Human Prolactin, also known by its gene name PRL, is a hormone produced by the pituitary gland. It is primarily responsible for promoting lactation in the mammary glands, but it also has pleiotropic effects in both males and females. Prolactin typically exists in two forms: a glycosylated and a non-glycosylated version. Each prolactin molecule is believed to bind with two PRL-receptor molecules. In addition to its role in lactation, peripheral prolactin production is associated with breast and prostate cancer development, regulation of reproductive function, and immune system control. Recent research has suggested that PRL has cytoprotective effects on pancreatic islet cells and liver tissue, which could be crucial for the success of transplantation in clinical settings.

Frequently Asked Questions
Are there any cross-species activity with this growth factor?
Yes, even though Human Prolactin shares approximately 60% to 65% similarity with rat and mouse prolactin, it can still trigger prolactin receptors from other species.
Why can’t I see a pellet in the vial?
Lyophilized powder may not be visible for many reasons including, but not limited to, dislodged powder being stuck on the cap or lack of carrier proteins that make the product difficult to see. Please tap or centrifuge the vial to bring all the material down to the bottom and reconstitute the product as outlined above.
Are there any stability concerns with freeze thawing?
Repeated freeze thawing is not recommended, as this may damage the protein products resulting in reduced functionality. After reconstitution, please aliquot into suitable sizes for one time use and freeze.
Can this product be used to culture cells other than human species?
Yes! We have seen this product successfully in a variety of cell cultures across land-dwelling and aquatic species.
Can I add BSA as a carrier?
Yes. Adding a carrier protein like BSA (0.1%) enhances protein stability, increases shelf-life, and allows the recombinant protein to be stored at a more dilute concentration.
Is this protein bioactive?
Yes, this protein was tested for activity on proliferation of NB2-11 cells.
Are volume discounts or recurring order discounts available for this product?
Yes. Please reach out to sales@futurefields.io to discuss your needs.
