CONTROL OF TEMPERATURE GRADIENTS DURING GEL ELECTROPHORESIS USING TURBULENT COOLANT GAS FLOW

摘要

A gel electrophoresis separation apparatus comprising, in combination, a gaseous heat-exchange medium, a gaseous heat-exchange medium driving means, and an impingement means, whereby the gaseous heat-exhange medium is driven by the gaseous heat-exchange medium driving means across the impingement means to provide a flow of the gaseous heat-exchange medium on the surface of the gel plates, whereby the flow induced by passage of the gaseous heat-exchange medium through the impingement means thereby minimizes temperature gradients within the gel by forced convection.
