[Direct positive DDP 111 as a possible means of documentation for electrophoresis].

The positivepaper DDP 111 manufactured in the Fotopapierwerk Dresden is presented. It allows to make copies (1:1) of electrophoreses. Independently of the used staining procedure it is a simple, quickly and cameraless possibly to obtain reproductions with a high quality.

[Experiences with ORWOANALYT base material ET 250 in the production of tissue supported ultrathin polyacrylic amide gel for IEF- and SDS-electrophoresis].

The "VEB Filmfabrik Wolfen" offers a textile material for sale, which is well suited for manufacturing of ultrathin reinforced polyacrylamide gels. In contrast to the glass- or polyester-stabilized gels such fabric-reinforced gels allow diffusion- or electroblotting methods. First experiences with ultrathin SDS- and IEF-gels, manufactured using this new supporting material are represented.
