- SynonymProlactin R,PRLR,PRL-R
- SourceHuman Prolactin R, Fc Tag (PRP-H5251) is expressed from human 293 cells (HEK293). It contains AA Gln 25 - Asp 234 (Accession # P16471-1).Predicted N-terminus: Gln 25Request for sequence
- Molecular Characterization
This protein carries a human IgG1 Fc tag at the C-terminus.
The protein has a calculated MW of 51.0 kDa. The protein migrates as 64 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.
- EndotoxinLess than 1.0 EU per μg by the LAL method.
- Purity
>95% as determined by SDS-PAGE.
- Formulation
Lyophilized from 0.22 μm filtered solution in Tris with Glycine, Arginine and NaCl, pH7.5. Normally trehalose is added as protectant before lyophilization.

Human Prolactin R, Fc Tag on SDS-PAGE under reducing (R) condition. The gel was stained overnight with Coomassie Blue. The purity of the protein is greater than 95%.
Immobilized Human Prolactin, Mouse IgG2a Fc Tag, low endotoxin (Cat. No. PRN-H5257) at 1 μg/mL (100 μL/well) can bind Human Prolactin R, Fc Tag (Cat. No. PRP-H5251) with a linear range of 2-39 ng/mL (QC tested).
Immobilized Human GH, Tag Free at 2 μg/mL (100 μL/well) can bind Human Prolactin R, Fc Tag (Cat. No. PRP-H5251) with a linear range of 0.4-6 ng/mL (Routinely tested).
- BackgroundAs a transmembrane receptor, the prolactin receptor (PRL-R) interacts with prolactin. In addition, the PRL-R also binds and is activated by growth hormone (GH) and human placental lactogen (hPL). Preclinical investigations, epidemiological studies and analyses of tissue specimens from patients strongly support the contribution of prolactin receptor (PRLR) signaling to breast and prostate tumorigenesis and cancer progression. Moreover, The PRLR has been found to be essential for lobuloalveolar maturation of the mammary glands during pregnancy, as evidenced by the fact that PRLR knockout mice show severely impaired development of lobuloalveolar structures.
