The shelf life is related to many factors, storage state, buffer ingredients, storage temperature and the stability of the protein itself.
Generally, the shelf life of liquid form is 6 months at -20°C/-80°C. The shelf life of lyophilized form is 12 months at -20°C/-80°C.
Introduction
Smallpox was an infectious disease unique to humans, caused by either of two virus variants, Variola major and Variola minor. The disease is also known by the Latin names Variola or Variola vera, which is a derivative of the Latin varius, meaning "spotted", or varus, meaning "pimple". The term "smallpox" was first used in Britain in the 15th century to distinguish variola from the "great pox" (syphilis). The last naturally occurring case of smallpox (Variola minor) was diagnosed on 26 October 1977.
Function
DNA-directed RNA polymerase-associated factor required for the transcription of viral early genes as well as for transcription termination. Within minutes after virus entry, recruits the core RNA polymerase, the early transcription factor (ETF) and other enzymes needed for transcription initiation, elongation, and termination thereby allowing synthesis of early mRNAs which are extruded through pores in the core particle. Recruits the multifunctional OPG102 protein, with poly(A) polymerase-stimulatory, cap nucleoside-2'-O-methyltransferase, and transcription elongation activities. Interacts with nucleoside triphosphatase I/OPG123, a DNA-dependent ATPase required for the termination of early transcripts. Acts as a transcription termination factor by binding, together with the capping enzyme/VTF, to the termination motif 5'-UUUUUNU-3' in the nascent mRNA. Involved as well in the packaging of RNA polymerase and other components needed for early transcription in assembling virus particles.
