The measurement of urinary creatinine is important in many situations, but perhaps most important when measuring the urinary content of substances other than creatinine. Because urine flow changes unpredictably during the day, but total creatinine ou

We report an improved "high-performance" liquid-chromatographic (HPLC) method for measuring biopterin and neopterin in serum and urine. Specimens are acidified, treated with iodine in 0.2 mol/L trichloroacetic acid, party purified on Bio-Rad MP-50 ca

Smokeless tobacco is a complex chemical mixture, including not only the components of the tobacco leaf but also chemicals added during the manufacturing process. Smokeless tobacco contains the addictive chemical nicotine and more than 20 cancer-causi

The authors obtained and evaluated antisera from rabbits injected with a derivative of a potent bladder carcinogen, dichlorobenzidine (DCB), conjugated to bovine serum albumin (BSA). A 14C-radioimmunoassay (RIA) was able to detect the presence of DCB

We evaluated and compared three analytical procedures for measuring creatinine by testing pooled sera and sera from individual human subjects. In two of the methods, an enzymic and a conventional colorimetric procedure, creatinine was separated from

Serum thyroxine (T4) levels were measured in serum pools by competitive protein binding radioassay (CPBR) with four kit procedures and an independent method. Thyroxine values in the pools analyzed were stable for three days at 25° and for l h at 45

An increase in apparent thyroxine values obtained by competitive protein-binding assay on storage of sera is well documented. We find that the major source of this positive bias is probably the unsaturated nonesterified fatty acids. Nonesterified fat

Factors involved in the optimization of competitive binding radioassays have been analyzed using a thyroxine (T 4 ) radioassay as a model system. The effects of kinetic errors are minimized by the use of the lowest possible incubation temperature for
