General description

Product Source: E. coli
Stem Cell Factor (SCF) is a hematopoietic growth factor that exerts its activity at the early stages of hematopoiesis. 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. Murine SCF is an 18.3 kDa protein containing 164 amino acid residues.

Application

Concentration Range for most in vitro applications is 1.0 - 100 ng/mL. Optimal working dilutions must be determined by end user.

Linkage

Replaces: GF049

Physical form

Lyophilized protein from 10 mM Sodium Phosphate, pH 6.5, containing no additives.

Storage and Stability

The lyophilized powder, though stable at room temperature, is best stored at -20°C for up to 12 months from date of receipt. After a quick spin, reconstitute with sterile water to a concentration of 0.1-1.0 mg/mL. This solution can be diluted into other buffered solutions and stored at 4°C for one week or at -20°C for future use. Reconstituted mouse SCF should be stored in working aliquots at -20°C for up to six months. Avoid repeated freeze/thaw cycles.

Analysis Note

Specific Activity: Murine SCF is biologically active when compared to standards.The ED(50), as determined by the dose-dependent stimulation of the proliferation of the human TF-1 cell line is ≤ 10 ng/mL
