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. Human SCF shows no activity on mouse cells, but mouse and rat SCF are active on human cells.

PODS™ crystals provide a depot of proteins which are steadily secreted. It has been estimated that the biolo gical activity of 50 million PODS™ crystals generates the same peak dose as 3.3 μ g of standard recombinant protein. However, at 5 days followin g the start of seedin g the PODS™ crystals, there are more than 50% of these peak levels still present in the culture system. Ultimately, the amount of PODS™ crystals that is optimal for a particular experiment should be determined empirically. Based on previous data, we su g gest usin g 50 million PODS™ crystals in place of 3.3 μ g of standard growth factor as a startin g point." To control for cross-reactivity with cells or as a ne gative control, we recommend usin g PODS™ growth factors alon gside PODS™ Empty crystals, as the latter do not contain or release car go protein.

Upon receipt, store at 4°C. PODS™ protein crystals are stable for at least 1 year when dry and 6 months when resuspended.
