A fast and sensitive in situ assay of deoxyribonucleic acid in miniaturized lattice cultures of fibroblasts is described. Tridimensional collagen and fibrin lattices prepared in 24-well plates were seeded with 50,000 to 200,000 cells. Cultures were fixed with formaldehyde, rinced
In the course of a study conducted to determine the correlation between covalently bound DNA-ethyl adducts and specific locus mutation induction in maize (W. E. Schy and M. J. Plewa Mutat. Res., 211, 231-241), it was necessary to accurately quantify
Procedures for collecting DNA from dilute solutions as small spots of the insoluble cetyltrimethylammonium salt deposited on either glass fiber or Millipore filters are described. This method of concentration facilitates the fluorescent assay of DNA, either by a microreaction in

In addition to normal decarboxylation of glutamate to 4-aminobutyrate, glutamate decarboxylase from pig brain was shown to catalyse decarboxylation-dependent transamination of L-glutamate and direct transamination of 4-aminobutyrate with pyridoxal 5'-phosphate to yield succinic semialdehyde and pyridoxamine 5'-phosphate in a 1:1
