Unlike higher order proteins and proteins complexes described in the next sections, the utility of the baculovirus expression vector system in the context of cytochrome P450s (CYP) comes from the ability to recover a microsomal fraction from infected cells containing both overexpressed CYP and oxidoreductase proteins.
Dektite Round Base Rubber Flashings. A range of round based rubber pipe flashings designed for use on profiled sheeting and flat panel surfaces.
