    Notes: Abstract A quantitative spectrofluorometer assay of urinary riboflavin is described. Using the method, levels produced by prescribed riboflavin are reliably distinguished from normal background levels without requiring dietary restrictions. The method is successfully used to verify the intake of a single 50-mg dose of riboflavin. However, when more frequent dosage is used, verification becomes unreliable because of a “spillover” effect produced by the slow rate of elimination of the substance. This seriously limits the utility of riboflavin as a tracer, as does its tendency to change the appearance of therapeutic compounds into which it is incorporated. The need for further work on validating combined measures of compliance is stressed.

    Notes: Abstract κ-Casein as purified from bovine milk exhibits a rather unique disulfide bonding pattern as revealed by SDS-PAGE. The disulfide-bonded caseins present range from dimer to octamer and above and preparations contain about 10% monomer. All of these heterogenous polymers, however, self-associated into nearly spherical uniform particles with an average radius of 8.9 nm as revealed by negatively stained transmission electron micrographs. Evidence is presented that multivalent cations play a role in the stabilization of these spherical particles. Treatment with EDTA causes disruption of theκ-casein particles and leads to a broader size distribution as judged by electron microscopy and dynamic light scattering. The size and shape of the particles are in accord with earlier proposed 3D models forκ-casein that actually predicted participation of divalent cations in the structure.
