- Format
- Lyophilized
- Reconstitution
- It is recommended that the lyophilized recombinant human stem cell factor (SCF) be reconstituted in sterile 18 M omega-cm H2O not less than 100 μg/mL, which can then be further diluted to other aqueous solutions.
- Buffer
- The protein was lyophilized after extensive dialysis against 20 mM HAc-NaAc, pH 4.5, 200 mM NaCl buffer.
- Handling Advice
- Avoid repeated freeze-thaw cycles.
- Storage
- -20 °C
- Storage Comment
- Lyophilized recombinant human stem cell factor (SCF) remains stable at room temperature for three weeks, but it is best stored desiccated below -18 °C. Upon reconstitution Recombinant Human Stem Cell Factor (SCF) should be stored at 4 °C for up to seven days. For long term storage it is recommended that a carrier protein (0.1% HSA or BSA ) be added.

- Background
-
Human Stem Cell Factor (SCF), produced in E. coli is a single, non-glycosylated polypeptide chain containing 165 amino acids and having a molecular mass of 18,409 Da. Stem Cell Factor (SCF) is a hematopoietic growth factor that exerts its activity during the early stages of hematopoiesis. Stem Cell Factor (SCF) stimulates the proliferation of myeloid, erythroid, and lymphoid progenitors in bone marrow cultures and has been shown to act synergistically with colony stimulating factors.
