IFIH1 is a DEAD box protein which is upregulated in response to treatment with beta-interferon and a protein kinase C-activating compound, mezerein. Irreversible reprogramming of melanomas can be attained by therapy with both these agents; treatment with either agent alone only achieves reversible differentiation. DEAD box proteins are implicated in several cellular processes involving alteration of RNA secondary structure such as translation initiation, nuclear and mitochondrial splicing, and ribosome and spliceosome assembly.
IFIH1 Human Recombinant produced in SF9 is a glycosylated, polypeptide chain having a calculated molecular mass of 152,000 Dalton. IFIH1 is expressed with a -10xHis tag at N-terminus and purified by proprietary chromatographic techniques.
IFIH1 is supplied in 20mM HEPES buffer pH-7.9, 550mM NaCl and 6M Urea.
Avoid multiple freeze-thaw cycles.
Greater than 93.0% as determined by SDS-PAGE.
