SCF Protein, Rat (P.pastoris)

SCF Protein, Rat (P.pastoris) is a hematopoietic cytokine, triggered by binding to its ligand c-kit, and plays an important role in hematopoiesis, spermatogenesis, and melanogenesis.

Stem Cell Factor is a hematopoietic cytokine, triggered by binding to its ligand c-kit, and plays an important role in hematopoiesis, spermatogenesis, and melanogenesis. Stem Cell Factor (SCF) is applied for hematopoietic stem cell mobilization, exvivo stem/progenitor cell expansion, gene therapy, and immunotherapy^[1]. Stem Cell Factor regulates cell survival, proliferation, differentiation, and migration in divergent cell types^[2].

The ED₅₀ is <25 ng/mL as measured by TF-1 cells, corresponding to a specific activity of >4 × 10⁴ units/mg.

Approximately 18.3 kDa

Greater than 95% as determined by reducing SDS-PAGE.

Lyophilized powder.

Lyophilized after extensive dialysis against PBS.

<0.2 EU/μg, determined by LAL method.

It is not recommended to reconstitute to a concentration less than 100 μg/mL in ddH₂O. For long term storage it is recommended to add a carrier protein (0.1% BSA, 5% HSA, 10% FBS or 5% Trehalose).

Stored at -20°C for 2 years. After reconstitution, it is stable at 4°C for 1 week or -20°C for longer (with carrier protein). It is recommended to freeze aliquots at -20°C or -80°C for extended storage.

Room temperature in continental US; may vary elsewhere.
