ELECTROPHORESIS APPARATUS AND A PLATE THEREFOR

摘要

The invention provides an electrophorsis apparatus comprising an electrophoretic chamber containing at least one two-plate housing (1) for a sieving matrix, each said at least one two-plate housing consisting of a cover plate and a plate for housing and sieving matrix, wherein said plate includes an optical waveguide array (2) which is characterized by being aligned with respect to a reference direction such as to enable one or more light beams incident on the sieving matrix along with said reference direction to be maintained well-confied along said reference direction within any desired length of interaction along the width of said sieving matrix.
