Placental Lactogen Ovine Recombinant ( Placental Lactogen Ovine )

Data sheet

Formulation

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

Solubility

It is recommended to reconstitute the lyophilized Placental Lactogen in sterile 18M-cm H2O not less than 100ug/ml, which can then be further diluted to other aqueous solutions.

Purity

Greater than 98.0% as determined by:(a) Analysis by SEC-HPLC.(b) Analysis by SDS-PAGE.

Description

Placental Lactogen Ovine Recombinant, is a single polypeptide chain containing 199 amino acids and an additional Ala at the N-terminus having a molecular mass of 23 kDa. Placental Lactogen Recombinant is purified by proprietary chromatographic techniques.

Protein Background

Placental Lactogen is a polypeptide hormone that is produced by the Syncytiotrophoblasts of the Placenta, also known as chorionic somatomammotropin. It has both Growth Hormone and Prolactin activities on growth, lactation, and luteal steroid production. I

Expression host

Escherichia Coli.

Synonyms

Chorionic Somatomammotropin Hormone 1, CSH1, CS-1, hCS, PL.

Reagent Appearance

Sterile Filtered White lyophilized (freeze-dried) powder.

Stability

Lyophilized Placental Lactogen Ovine Recombinant although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution Placental Lactogen should be stored at 4°C between 2-7 days and for future use below -18°C.For l

Amino acid sequence

The sequence of the first five N-terminal amino acids was determined and was found to be Ala-Gln-His-Pro-Pro.

Biological Activity

Placental Lactogen Ovine is biologically active as evidenced by inducing proliferation of Nb2 cells.
