Cat#:RP-2377HAT;Product Name:Recombinant Human Prolactin Protein;Description:Prolactin is a hormone synthesised and secreted by lactotrope cells in the adenohypophysis(anterior pituitary gland). Prolactin has many effects, the most significant of which is to stimulate the mammary glands to produce milk (lactation).Increased serum prolactin during pregnancy causes enlargement of the mammary glands of the breasts and increases the production of milk. Recently, prolactin has demonstrated broader roles in breast cancer development, regulation of reproductive function, and immunoregulation. Prolactin was produced in E.coli and purifed using the chromatography, after refolding of the isolated inclusion bodies in a renaturation buffer.;Source:E.coli;AA Sequence:29-227aa;Molecular Characterization:23 kDa;Purity:Greater than 95% by SDS-PAGE;Endotoxin:< 1.0 EU per ug of protein as determined by LAL method.;Bioactivity:Measured in a cell proliferation assay using Nb2-11 Rat lymphoma cells. The ED50 for this effect is less or equal to 0.5 ng/ml.;Formulation:Liquid Solution;Stability:Recombinant Human Prolactin Protein was stable up to 1 year from date of receipt at -70℃;Concentration:1mg/mL;Storage Buffer:Recombinant Human Prolactin protein was supplied in PBS (pH 7.4);Storage:Recombinant Human Prolactin Protein can be stored at +4℃for 1-2 weeks.
