DATA SHEET:Recombinant HUMAN Prolactin

Prolactin, also known as mammotrophin, luterotropic hormone, and lutetropin, is a neuroendocrine hormone secreted by the pituitary gland. Its primary function is to promote and maintain lactation during pregnancy and suckling. In addition, Prolactin plays an immune-regulatory role by stimulating the activities of ornithine decarboxylase and protein kinase C, which are important for the proliferation, differentiation and function of lymphocytes. This recombinant Human Prolactin is a 23 kDa globular protein containing 200 amino acid residues.

Supplied: Lyophilized protein from 10mM sodium Phosphate pH8.0 + 50mM NaCl with no additives.

Source: E. Coli

Purity: >95% by SDS-Page analysis. Endotoxin level is less than 0.1ng per ug (1EU/ug) of human Prolactin.

Reconstitution: The lyophilized Prolactin is soluble in water and most aqueous buffers. The lyophilized powder should be reconstituted in water, to a concentration of 0.1-1.0mg/ml. Allow to set at least 30 minutes at 4 DEG C. If desired, can centrifuge for 1 minute at 1000 rpm to concentrate material in vial. This solution can be diluted into water or other buffered solutions or stored at -20 DEG C for future use.

Note:If this material is not to be used for coating or labeling (or other applications requiring carrier free material), the addition of 0.1% BSA to dilution buffers or dilution in sterile culture media is recommended to enhance stability and minimize absorption to vial. Ideally, maintain stock >50ug/ml.

Storage: The lyophilized powder, though stable at room temperature for a few weeks, is best stored dessicated at -20 DEG C. Reconstituted material should be stored in working aliquots at -20 DEG C. Avoid Frequent Freeze-THAW Cycles.

Reactivity: Determined by its ability to induce the proliferation of rat Nb2-11 cells in the concentration range of 0.1-1.0 ng/ml.
