Abstract
An improved coated plastic mold for the polymerization of electrophoresis gels. The mold controls the effects of oxygen contamination upon gel polymerization resulting in a more uniform gel with improved properties.
Claims17
A mold for an electrophoresis gel comprising:
- a plastic support structure having at least one interior surface defining a cavity;
- and
- an SiOx layer consisting essentially of SiOx disposed between at least a portion of said interior surface and said cavity;
- wherein the SiOx layer forms an oxygen barrier having an oxygen permeability of no more than 1 cc-mil/m.sup.2 -atm-day, and the SiOx layer has an oxygen transmission rate of no more than 2 cc/m.sup.2 -atm-day.
1 more element
A medium for electrophoresis comprising:
- a plastic support structure defining a cavity;
- an aqueous electrophoresis gel within said cavity;
- and
- an oxygen barrier disposed between said plastic support structure and said aqueous electrophoresis gel;
- wherein said oxygen barrier comprises a layer including an SiOx layer consisting essentially of SiOx;
- and
- wherein said SiOx layer has an oxygen permeability no more than 0.01 cc-mil/m.sup.2 -atm-day, and said SiOx layer has an oxygen transmission rate of no more than 2 cc/m.sup.2 -atm-day.
4 more elements
A medium for electrophoresis comprising:
- a plastic support;
- an aqueous electrophoresis gel;
