Prolactin Mouse, PEG

Pegylated Prolactin Mouse Recombinant is a single non-glycosilated polypeptide chain having a molecular mass of ~ 39 kDa containing 199 amino acids and an additional Ala at N-terminus Prolactin Mouse was purified by proprietary chromatographic techniques. 

Escherichia coli.

White lyophilized (freeze-dried) powder.

The Mouse Prolactin was lyophilized from a concentrated (1mg/ml) solution with 0.02-0.03% NaHCO₃.

It is recommended to reconstitute the lyophilized Prolactin Mouse in sterile water or sterile 0.4% NaHCO3adjusted to pH 8-9, not less than 100µg/ml, which can then be further diluted with other aqueous solutions.

Lyophilized Prolactin Mouse although stable at room temperature for several weeks, should be stored desiccated below -18°C. Upon reconstitution at > 0.1 mg/ml and up to 4 mg/ml and filter sterilization Prolactin mouse can be stored at 4°C for several weeks.

Please prevent freeze-thaw cycles.

Greater than 97.0% as determined by: 

(a) Gel filtration analysis.

(b) Analysis by SDS-PAGE.

Pegylated Mouse Prolactin inhibits proliferation of Nb2 cells or Baf/3 cells stably transfected with human prolactin receptors, though its activity is lower than pegylated human prolactin. However, it is anticipated that its activity in vivo in mice will be higher due to prolonged persistence in circulation.

Protein quantization was carried out by UV spectroscopy at 280 nm using the absorbency value of 0.675 as the extinction coefficient for a 0.1% (1mg/ml) solution at pH 8.0. This value is calculated by DNAman computer analysis program of protein sequences.

Prolactin aka as lactotropin and mammotropin, is a neuroendocrine hormone synthesized primarily by the pituitary gland in response to eating but also a variety of other cell types including the placenta, brain and uterus. Prolactin takes part in metabolism, regulation of the immune system and pancreatic development. Its primary function is to promote and maintain lactation but has also been shown to have a role in breast cancer development, regulation of reproductive function and immunoregulation.
