Source

Biotinylated Human Prolactin R Protein, His,Avitag (PRR-H82E3) is expressed from human 293 cells (HEK293). It contains AA Gln 25 - Asp 234 (Accession # P16471-1).

Predicted N-terminus: Gln 25

Molecular Characterization
Other Tags and Version Biotin & Other Labeled Version

This protein carries a polyhistidine tag at the C-terminus, followed by an Avi tag (Avitag™).

The protein has a calculated MW of 28.0 kDa. The protein migrates as 33-38 kDa when calibrated against Star Ribbon Pre-stained Protein Marker under reducing (R) condition (SDS-PAGE) due to glycosylation.

Labeling

Biotinylation of this product is performed using Avitag™ technology. Briefly, the single lysine residue in the Avitag is enzymatically labeled with biotin.

Protein Ratio

Passed as determined by the SABA assay / HABA assay / binding ELISA.

Purity

>95% as determined by SDS-PAGE.

>95% as determined by SEC-MALS.

Formulation

Lyophilized from 0.22 μm filtered solution in PBS, pH7.4 with trehalose as protectant.

Background

The prolactin receptor (PRLR) is a transmembrane protein belonging to the class I cytokine receptor superfamily, widely expressed in mammary gland, reproductive organs, liver, and brain. Signal activation is initiated when a single prolactin (PRL) molecule binds to this pre-dimerized PRLR, inducing a specific conformational change. This triggers the associated JAK2 kinases to phosphorylate each other and the receptor, ultimately leading to the recruitment and activation of downstream STAT5 transcription factors. This precise mechanism governs essential physiological processes, including lactation, reproduction, metabolism, and immune function, and its dysregulation is implicated in diseases such as certain cancers and endometriosis.
