We present the preparation of an ion exchange paper which can be used as a solid carrier in the transfer of RNA from gels. In addition to detection by blot hybridization to specific probes, transferred RNA can be characterized by cell-free translation in situ. Preparation of the paper is simple, inexpensive and reproducible. Examples of applications are shown and possible other applications are...

The importance of plasma momentum fluxes in fusion reactor divertor operation is noted. Direct measurements have been made of the momentum flux from magnetized He, Ne, AI and Kr plasmas onto solid carbon targets oriented normal to the magnetic field, as the target bias was varied between 50 and + 40 volts. The inferred ion energies are compared with fluid sheath theory. Corrections due to kinet...

Rapid synthesis of oligodeoxyribonucleotides is described by a solid phase method. Polysterene grafted on the surface of polytetrafluoroethylene has been found to be an adequate support. The properties of the support were studied in the synthesis of a number of oligonucleotides 6 to 15 nucleotides long. A flow-type semi-automatic synthesizer has been used. Each nucleotide addition involves seve...

Recycling treatment of cable insulation resin generated from electric wires and cables was investigated. Conventional insulation PVC contains a lead component, tribase, as a thermal stabilizer and lead removal is necessary to recycle this PVC as insulation resin. This paper describes a solid surface adsorption method using ion exchange resin to remove the fine lead containing particles from PVC...
