Hu Recom Heregulin-beta 1, 10 µg

STEMCELL Technologies offers Human Recombinant Heregulin-beta 1, a bioactive protein reported to modulate cell growth and differentiation of cells during development and wound healing and to promote metastasis of breast tumor cells.

Biological activity was assessed by its ability to promote the proliferation of MCF-7 cells, measured using a fluorometric assay method. The EC50, defined as the effective concentration of the growth factor at which cell proliferation is at 50% of maximum, is less than 0.1 ng/mL. When resolved by SDS-PAGE under reducing and non-reducing conditions and stained with Coomassie Blue, Human Recombinant Heregulin-beta 1 shows a predicted molecular mass of 7.5 kDa.
