We describe an improved radioimmunoassay method for serum digoxin, with 125I as tracer, to eliminate the problems that endanger the validity of this assay: apparent instability of tracer, time-dependence of charcoal separation of free and bound fract

We describe a simple, direct, and specific manual method for quantitative determination of total cholesterol in serum. In the method, which requires no extraction of the serum, a single stable reagent and 50 µl of sample is used. Serum cholesterol c

Phytase activity has been demonstrated to be widely distributed in the rat, the highest activity being found in the intestinal mucosa. The relative distribution of this enzyme parallels closely the known relative distribution of alkaline phosphatase

A study with rats of the role played by vitamin D in overcoming the rachitogenic properties of high-Ca phytic acid containing diets has shown that phytic acid in a low-Ca cereal ration was hydrolyzed almost completely even when vitamin D was absent.

A column method utilizing the anion-exchange rosin Dowex-1 is described for the determination of thyroxine in serum. Values comparable to those for butanol-extractable iodine were obtained, and additions of inorganic iodine or iodotyrosines did not a

A relatively simple and rapid radioimmunoassay for the determination of aldosterone in urine has been developed, employing tritiated aldosterone and a commercially available antiserum of high titer. Chromatography of specimens prior to immunoassay ha
