A simple method is described for the determination of the levels of phosphorylated lipopro-ลฝ . teins e.g., vitellins and vitellogenins in biolog-ลฝ . ical fluids or tissues. Vitellogenin Vg is a very high density lipophosphoprotein and its synthesis is activated by estrogens in oviparous organisms.

Details are provided for a reproducible procedure for determination of labile sulfide in ironsulfur (Fe-S) proteins in the range of 1 to 3 nmol. Analyses are also presented on the most stable Fe-S protein so far reported. In this case denaturation with guanidine . HCl was used in the presence of dit
Verapamil concentrations in blood, urinee, or tissue homogenates may be measured fluorometrically in the 0.1-10-mug/ml range after extraction into heptane and back-extraction into acid; recovery rates are above 87%. The drug apparently is eliminated rapidly in guinea pigs, with a plasma half-life of
