Recombinant Human Prolactin
Induced proliferation of NB2-11 cells assay for Human Prolactin. Cell proliferation was measured to calculate the ED50, which is as expected less than 1 ng/ml.
Non-reducing (-) and reducing (+) conditions in a 4 - 20% Tris-Glycine gel stained with Coomassie Blue. 1 μg of protein was loaded in each lane. Human Prolactin has a predicted Mw of 23.0 kDa.

Prolactin is a hormone that is produced and secreted by the pituitary gland. Prolactin acts in an endocrine, paracrine, and autocrine manner. The prolactin receptor (PRLR) is expressed on many cell types, including cells of the reproductive organs, central nervous system, and breast cancer. Prolactin signal transduction occurs via JAK kinase signaling pathways. The primary function of prolactin is to regulate lactation, but prolactin also plays functional roles in the immune system and during cell growth, apoptosis, and differentiation.Activity Assay
Human Prolactin is fully biologically active when compared to standard. The activity is determined by the ability to induce NB2-11 cells proliferation and it is typically less than 1 ng/ml. This corresponds to an expected specific activity of 1 x 106 units/mg.AA Sequence
