ATP: POLYNUCLEOTIDE ADENYLYLTRANSFERASE ENZYME AND METHOD OF PREPARATION THEREOF
ENZYMATIC REACTIONS USING MAGNETIC PARTICLES
Rusty J Mans assigned to University of Florida The invention relates to ATP: polynucleotide adenylyltransferase enzyme and a method for its preparation comprising extraction from monocotyledonous plant tissue and chromatographic separation.
Roy A Whitehead, Mark S Chagnon, Ernest V Groman, Lee Josephson assigned to Advanced Magnetics Inc A process is provided for the preparation of magnetic particles to which a wide variety of molecules may be coupled. The magnetic particles can be dispersed in aqueous media without rapid settling and conveniently reclaimed from media with a magnetic field. Preferred particles do not become magnetic after application of a magnetic field and can be redispersed and reused. The magnetic particles are useful in biological systems involving separations.
