A technic, efficient in use of I 131 , has been developed for introducing I 131 into 4-mg. amounts
of antibody or γ-globulin protein at a level of 10 mc. I 131 per mg. protein with a resulting …

A modified iodine monochloride method suitable for preparing I 131 -labeled proteins of a
high degree of radioactivity is described, and results are given. Hydrogen peroxide present in …

A detailed study has been made of the iodine monochloride method of protein iodination. In
particular, the losses of I 131 , which may be incurred in the preparation of labeled γ-…

A procedure for the synthesis of a hexahydro-2-oxo-4-methyl-l-furo [3, 4] imidazole isomer
has been described. This synthesis involves catalytic hydrogenation of the appropriate furan …

A new radioactive reagent, diazotized [ 131 I] diiodosulfanilic acid, which binds specifically
to protein groups of the erythrocyte membrane, is described. The labeling reaction and some …

A procedure is described for oxidizing the total iodine in “carrier-free” NaI 131 preparations
to ICl under conditions such that the resulting solution can be used directly for production of I …

The monophenyl and monomethyl esters of a-phenyl-/3-bromoß-^-chlorobenzoylethyl-phosphonic
acid havebeen prepared and their behaviors in alkaline solution studied. 2. The two …

In the attempt to prepare DL-lysine labeled with C14 for use in metabolic stud-ies, our initial
efforts were directed toward the development of a method which would permit the …

The 210 Po in relatively large volumes of dilute hydrochloric acid (900–1800 ml) and of
acidified urine (2 × 1335 to 2 × 1700 ml), spiked with equilibrated 210 Pb− 210 Bi− 210 Po, was …

From the reaction mixture it is possible to isolate, in addition to the cyclohexanone derivative,
two compounds isomeric with it. These substances are evidently stereoisomers having the …
