Hepatic leukemia factor, HLF.
Hepatic leukemia factor (HLF) is a member of the bZIP family and the PAR (proline and acidic-rich) subfamily of transcription regulatory proteins. HLF binds DNA specifically as a homodimer or heterodimer with other PAR factors. HLF is highly expressed in the liver, with lower levels in the lung and kidney and functions as an effective trans-activator.
HLF Human Recombinant produced in E.Coli is a single, non-glycosylated polypeptide chain containing 315 amino acids (1-295 a.a.) and having a molecular mass of 35.3kDa.
HLF is fused to a 20 amino acid His-tag at N-terminus & purified by proprietary chromatographic techniques.
HLF protein solution (0.25mg/ml) containing 20mM Tris-HCl buffer (pH8.0), 40% glycerol, 0.2M NaCl and 0.1mM PMSF.
Store at 4°C if entire vial will be used within 2-4 weeks. Store, frozen at -20°C for longer periods of time.
For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).
Avoid multiple freeze-thaw cycles.
