Package: 0.1mg and 1mg
Species: Human
Expression System: E. Coli
Molecular Weight: The protein has a calculated MW of 15.7 kDa, and is observed at 17 kDa under reducing condition (SDSPAGE
analysis).
Purity: > 95 % as determined by SDS-PAGE
Formulation: Lyophilized form
Biological Activity: ED50 is < 0.1 ng/ml. ED50 was determined by a cell proliferation assay using CTLL-2 cells.
Endotoxin: <0.5 EU/μg as determined by LAL method
Storage buffer: 20 mM phosphate, 150 mM NaCl, pH 7.4
Storage instructions: Store the lyophilized protein at -20℃ to -80℃ for long-term. After reconstitution, the protein solution is stable at -20℃ for 3month, at 2-8℃ for up to 1 week. Avoid repeated freeze/thaw cycles.
