ActoFactor™ Recombinant Rat Prolactin receptor

  • Specification
  • Recommended Products
Cat.No.
CSC-CTK0802
Description
Prolactin is a pituitary hormone involved in the stimulation of milk production, salt and water regulation, growth, development and reproduction. The initial step in its action is the binding to a specific membrane receptor (prolactin receptor) which belongs to the superfamily of class 1 cytokine receptors. The function of the prolactin receptor is mediated, at least in part, by two families of signaling molecules: Janus kinases and signal transducers and activators of transcription. Prolactin (PRL) is a hormone involved in a variety of important functions including ion transport and osmoregulation, stimulation of milk, protein synthesis as well as the regulation of numerous reproductive functions. PRL exerts its influence on different cell types through a signal transduction pathway which begins with the binding of the hormone to a transmembrane PRL receptor. Immunoreactive PRL receptor, a member of the cytokine receptor family, varies in size (short and long forms) with tissue source and species, from ~40 kDa to 100 kDa. The PRL receptor consists of at least three separate domains: an extracellular region with 5 cysteines which contains the prolactin binding site, a single transmembrane domain and a cytoplasmic region, the length of which appears to influence ligand binding and regulate cellular function. Recombinant Rat Prolactin Receptor (Extracellular Domain) produced in E. coli is a non- glycosylated, polypeptide chain containing 206 amino acids and having a molecular mass of 24,120 Dalton. The Prolactin Receptor has been purified by proprietary chromatographic techniques.
Species
Rat
Product Overview
Rat Prlr expressed in E.coli
Molecular Mass
24.1 kDa
Size
CAT# CSC-CTK0802-20 (20 μg); CAT# CSC-CTK0802-100 (100 μg)
Expression System
E.coli
Purity
Greater than 97% as determined by SDS-PAGE and SEC-HPLC analysis.
Activity
Activity has been determined by the dose-dependant inhibition of Prolactin-stimuled proliferation of Nb2 cells and by high affinity binding of oPLR and other lactogenic hormones.
Endotoxin Level
N/A
Formulation
Sterile-filtered, white, lyophilized (freeze-dried) powder. The protein was lyophilized from a concentrated (1 mg/ml) solution with 0.0045 mM NaHCO .
Reconstitution
Please centrifuge product briefly before opening vial. The lyophilized protein should be reconstituted in sterile, ultrapure water or aqueous buffers to a concentration of 0.1 - 1.0 mg mg/ml. This solution can then be diluted into other aqueous buffers and stored at -20°C for future use.
Storage & Stability
The lyophilized protein, though stable at room temperature for up to 3 weeks, is best stored desiccated at -20°C. Reconstituted protein should be used immediately or stored long-term in undiluted working aliquots at -20°C. For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA). Avoid repeated freeze-thaw cycles.
