Product Datasheets
Carrier Free
CF stands for Carrier Free (CF). We typically add Bovine Serum Albumin (BSA) as a carrier protein to our recombinant proteins. Adding a carrier protein enhances protein stability, increases shelf-life, and allows the recombinant protein to be stored at a more dilute concentration. The carrier free version does not contain BSA.
In general, we advise purchasing the recombinant protein with BSA for use in cell or tissue culture, or as an ELISA standard. In contrast, the carrier free protein is recommended for applications, in which the presence of BSA could interfere.

Background: Prolactin
Prolactin (gene name PRL) is a secreted neuroendocrine pituitary hormone that acts primarily on the mammary gland to promote lactation, but has pleiotropic effects in both males and females (1-3). Mouse Prolactin is predominantly found as 23 kDa non-glycosylated monomers. Mouse prolactin shares 60% and 85% amino acid sequence identity with human and rat prolactin, respectively; however, activation of the human prolactin receptor by rat prolactin has been demonstrated (3). Prolactin is synthesized mainly by the anterior pituitary in all mammals, where secretion is under tonic inhibition by hypothalamic dopamine (2, 3). Secretion can be stimulated by suckling and diurnally by estradiol in rodents during pro-estrus and mating (2). In humans prolactin is also produced peripherally, while in rodents, the only known non-pituitary source is the placenta (1-3). Mouse serum Prolactin declines until mid-pregnancy, but increases in late pregnancy (1). Post-translational modifications such as polymerization, phosphorylation, and proteolytic cleavage can alter the activities of prolactin (3). Cleavage by matrix metalloproteinases or Cathepsin D can produce N-terminal 16 kDa antiangiogenic fragments also called vasoinhibins (4, 5). Thrombin can produce C-terminal 16 kDa fragments that are not antiangiogenic (3). The prolactin receptor (gene name PRLR) is a transmembrane type I glycoprotein that belongs to the cytokine hematopoietic receptor family. Expression of the prolactin receptor is widespread (2, 3). Each prolactin molecule is thought to bind two receptor molecules (6).
