  • CSC-CTK0293
  • Description
  • Stem Cell Growth Factor (SCGF) is a newly discovered hematopoietic growth factor that exerts its activity at the early stages of hematopoiesis. Human SCGF is a non-glycosylated 33.9 kDa species-specific cytokine of 305 amino acids that can support growth of primitive hematopoietic cells, and in combination of EPO or GM-CSF, it promotes proliferation of erthroid and myeloid progenitors, respectively.

  • Expression System
  • E.coli
  • Purity
  • Greater than 98% as determined by SDS-PAGE and HPLC analyses. Endotoxin level is less than
  • Activity
  • Determined by its inhibitory effect on the proliferation of TF-1 cells previously grown in media containing GM-CSF. The ED50 for this effect is 2.5 ng/ml.
  • Endotoxin Level
  • Less than 1 EU/μg.
  • Formulation
  • Lyophilized from a sterile-filtered protein solution with no additives.
  • Reconstitution
  • Please centrifuge product briefly before opening the vial. The lyophilized SCGF is soluble in water and most aqueous buffers. The lyophilized protein should be reconstituted in sterile, ultra-pure water to a concentration of 0.1-1 mg/ml. It is recommended that further dilutions be made into buffer containing carrier protein (HSA or BSA) or medium containing serum.
  • Storage & Stability
  • The lyophilized SCGF, though stable at room temperature for up to 3 weeks, is best stored desiccated at -20°C. Reconstituted SCGF should be used immediately or stored long-term in undiluted working aliquots at -20°C.
