产品描述 概述Prolactin 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. The prolactin receptor is a transmembrane type I glycoprotein that belongs to the hematopoietic cytokine receptor family. 使用说明This material is offered by Novin Biotech for research, laboratory or further evaluation purposes.
