Specifications

Catalog #S7973-30U
SourceRecombinant corresponding to 165aa of human Stem Cell Factor expressed in E.coli is a single, non-glycosylated polypeptide chain.
Molecular Weight~18.4kD
Biological ActivityThe ED50 as determined by the dose-dependent stimulation of human TF-1 cellsis less then 2ng/ml, corresponding to a Specific Activity of 105 IU/mg.
Dimers and Aggregates 1% (SDS-PAGE)
Protein ContentProtein quantitation was carried out by two independent methods:1. UV spectroscopy at 280nm using the absorbency value of 0.52 as the extinction coefficient for a 0.1% (1mg/ml) solution. This value is calculated by the PC GENEcomputer analysis program of protein sequences (IntelliGenetics). 2. Analysis by RP-HPLC, using a standard solution of SCF as a Reference Standard.
Storage and StabilityLyophilized powder may be stored at -20°C. Stable for 12 months at -20°C. Reconstitute with sterile ddH2O, HSA or BSA. Aliquot to avoid repeated freezing and thawing. Store at -20°C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.
Molecular Weight~18.4kD
Purity~98% (RP-HPLC, Anion-exchange FPLC, SDS-PAGE) Endotoxin: 0.1ng/ug (IEU/ug)
Concentration~1mg/ml
FormSupplied as a lyophilized powder. No preservative added. Reconstitute with sterile dH2O, 0.1% HSA or BSA to 0.1mg/ml.
