Mild periodate oxidation of certain commercially available crosslinked agarose beads (Sepharose CL-4B and CL-6B) results in the generation of aldehydo groups which were useful for immobilization of amino compounds by reductive amination using pyridine borane.

A rapid method for the preparation of [ I-'4C]acetyl-~-carnitine is described. The method involves exchange of [ I-'%]acetic acid into a pool of unlabeled acetyl-L-carnitine using the enzymes acetyl-CoA synthetase and carnitine acetyltransferase. After isotopic equilibrium is attained, radioactive a
ABA block copolymers, where A and B represent polyamide and polystyrene segments respectively, were prepared by the anionic polymerization of caprolactam activated with polystyrene-bisacyllactams. Under mild polymerization conditions (in a solvent at 120Β°), very pure copolymers were obtained contain
