SPECIES:Human
SOURCE SPECIES:P. pastoris
SEQUENCE:Cys24-Glu188
FUSION TAG:Tag Free
TESTED APPLICATIONS:
APPLICATIONS:This recombinant protein can be used for biological assays. For research use only.
BIOLOGICAL ACTIVITY: Specific Activity is 5.0 x 106 IU/mg as determined by a viral resistance assay using VSV-WISH cells.
psi-iconProperties
PURITY:Greater than 95% as determined by reducing SDS-PAGE.
Endotoxin level less than 0.1 ng/ug (1 IEU/ug) as determined by LAL test.
PREDICTED MOLECULAR WEIGHT:85.7 kD
PHYSICAL STATE:Lyophilized
BUFFER:Lyophilized from a 0.2 um filtered solution of 20mM PB, 150mM NaCl, pH 7.2. It is not recommended to reconstitute to a concentration less than 100 ug/ml. Dissolve the lyophilized protein in ddH2O.
STORAGE CONDITIONS:Lyophilized protein should be stored at -20˚C, though stable at room temperature for 3 weeks.
Reconstituted protein solution can be stored at 4-7˚C for 2-7 days.
Aliquots of reconstituted samples are stable at -20˚C for 3 months.

psi-iconBackground and References
BACKGROUND:At least 23 different variants of Interferon- alpha are known. The individual proteins have molecular masses between 19-26 kD and consist of proteins with lengths of 156-166 and 172 amino acids. All IFN- alpha subtypes possess a common conserved sequence region between amino acid positions 115-151 while the amino-terminal ends are variable. Many IFN- alpha subtypes differ in their sequences at only one or two positions. Naturally occurring variants also include proteins truncated by 10 amino acids at the carboxyl-terminal end.
