Human Prolactin R / PRLR Protein, His Tag

分子别名(Synonym)

Prolactin R,PRLR,PRL-R

表达区间及表达系统(Source)

Human Prolactin R, His Tag (PRR-H52Ha) is expressed from human 293 cells (HEK293). It contains AA Gln 25 - Asp 234 (Accession # P16471-1).

Predicted N-terminus: Gln 25

蛋白结构(Molecular Characterization)

Online(Gln 25 - Asp 234) P16471-1

This protein carries a polyhistidine tag at the C-terminus.

The protein has a calculated MW of 26.3 kDa. The protein migrates as 35-40 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.

内毒素(Endotoxin)

Less than 1.0 EU per μg by the LAL method.

纯度(Purity)

>95% as determined by SDS-PAGE.

制剂(Formulation)

Lyophilized from 0.22 μm filtered solution in 50 mM Tris, 150 mM NaCl, pH7.5. Normally trehalose is added as protectant before lyophilization.

活性(Bioactivity)-ELISA

Biotinylated Human ELISA

Immobilized Human Prolactin, Mouse IgG2a Fc Tag, low endotoxin (Cat. No. PRN-H5257) at 5 μg/mL (100 μL/well) can bind Human Prolactin R, His Tag (Cat. No. PRR-H52Ha) with a linear range of 20-156 ng/mL (QC tested).

Protocol

Biotinylated Human SPR

Immobilized Human GH, Tag Free at 5 μg/mL (100 μL/well) can bind Human Prolactin R, His Tag (Cat. No. PRR-H52Ha) with a linear range of 0.313-5 μg/mL (Routinely tested).

Protocol

背景(Background)

As 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.
