Stem Cell Growth Factor alpha (SCGF-alpha) is a hematopoietic growth factors that exerts its activity at the early stages of hematopoiesis and can support growth of primitive hematopoietic cells.
>98% by SDS Page and HPLC
The biological activity of Human Stem Cell Growth Factor-Alpha is determined by its inhibitory effect on the proliferation of TF-1 cells previously grown in media containing GM-CSF. The ED50 for this effect was observed at 2.5 ng/mI.
