Recombinant Human SCF
Stem cell factor (SCF) is a cytokine made by fibroblasts and endothelial cells. SCF binds to the receptor c-Kit/CD117 and plays a critical role in the maintenance, survival, and differentiation of hematopoietic stem cells. While human SCF shows no activity on murine cells, murine and rat SCF are active on human cells.

SDS-PAGE Showing a Single Prominent Band ~15 kDa
Figure 1. rh SCF (1 μg) was resolved with SDS-PAGE under reducing (R) conditions and visualized by InstantBlue staining showing a prominent band at ~15 kDa.*
*Predicted MW is 18.6 kDa, but runs on SDS-PAGE at ~15 kDa.
Cell-Based Proliferation Assay
