Introduction
Placental Lactogen is a polypeptide hormone that is produced by the Syncytiotrophoblasts of the Placenta.Placental Lactogen has both GH and Prolactin activities on growth, lactation, and luteal steroid production. In women, placental lactogen secretion begins soon after implantation and increases to 1 g or more a day in late pregnancy. Placental Lactogen Bovine is also capable of activating human and other heterologous GH receptors.
Description
Placental Lactogen Human produced in Sf9 Baculovirus cells is a single, glycosylated polypeptide chain containing 197 amino acids (27-217 aa) and having a molecular mass of 23.1kDa.
Placental Lactogen is fused to a 6 amino acid His tag at C-terminus and purified by proprietary chromatographic techniques.
Source
Sf9, Baculovirus cells.
Physical Appearance
Formulation
The Placental Lactogen solution (0.25mg/ml) contains 30% Glycerol and Phosphate-Buffered Saline (pH 7.4).
Stability
For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).
Avoid multiple freeze-thaw cycles.
Purity
Greater than 90.0% as determined by SDS-PAGE.
Biological Activity
Determined by cell proliferation assay using Nb2-11 Rat lymphoma cells. ED50 range for this effect is ≤ 0.8 ng/ml.
