Conjugations
Unconjugated
Predicted Molecular Weight
~8 kDa
Expression System
E. coli
Source Species
Escherichia coli
Purification
Greater than 95% by SDS-PAGE
Bio-Activity
Determined by its ability to inhibit human FGF-basic-dependent proliferation of NR6R-3T3 mouse fibroblasts. The ED50 for this effect is typically 5-15 µg/mL.
Endotoxin
Less than 1.0 EU/µg protein (determined by LAL method).
Presentation
Lyophilized from sterile 20 mM PBS, pH 7.4, 1.5 M NaCl
Reconstitution
Reconstitute in distilled water to 0.1 mg/ml.
Storage
The lyophilized protein is stable for up to 1 year at -70°C. Upon reconstitution, this cytokine can be stored in working aliquots at 2°C to 8°C for 1 month, or at -20°C for 6 months, with a carrier protein without detectable loss of activity. Avoid freeze/thaw cycles.
Restrictions
For research use only. Intended for use by laboratory professionals.
