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. The original watertight flashing for hot or cold flues and pipes on metal roofs. A tough weathertight seal and a strong flexible base, the all-in-one flashing that started the revolution.
The counter flashing can be made of a wide variety of materials. It can be wood siding, stucco, vinyl or aluminum siding, or other material which forms the outside surface of a wall. In chimneys and along brick walls, the counter flashing is almost always the same metal which is used for the base or step flashing. Two part metal flashing systems are not harmed in any way by the sun's ultra-violet (UV) rays. UV rays can easily defeat caulking, plastic roof cement or most other flashing substitutes. UV radiation can remove the elasticity of these products and make them brittle.
