title: Nucleotides in a single mammalian ovum or preimplantation embryo.
abstract: ATP, ADP, and AMP have been measured jointly on a single mouse ovum or preimplantation embryo using an ultramicrofluorescence technique. The method uses the traditional approach of enzymatic analysis based on changes in the concentrations of nucleotide cofactors, but eliminates the need for enzymatic recycling. It permits the measurement of as little as 10 fmol, and may be adapted for numerous metabolites.
