Microdetermination of Proline in Serum.

Microdetermination of serum calcium using the Eel flame photometer.

Determination of Chlorides in Biological Fluids by the Use of Adsorption Indicators the Use of Dichlorofluorescein for the Volumetric Microdetermination of Chlorides in Cerebro- Spinal Fluids and Blood Serum by Abraham Saifer

Automated, simultaneous microdetermination of calcium and magnesium by atomic absorption.

A procedure is described for the simultaneous, automatic determination of serum calcium and magnesium with the AutoAnalyzer, and a dualchannel, double-beam atomic absorption spectrophotometer, the IL Model 153. Advantages over existing procedures include a high rate of analysis (90 samples or 180tests per hour) and low sample consumption (a total of 30 l for both determinations). We have compar...

Lectin affinity electrophoresis of alpha-fetoprotein detected by immunoenzymatic and chemiluminescent amplification followed by direct scanning.

Microdetermination of alpha-fetoprotein (AFP) glycoforms by lectin affinity electrophoresis followed by chemiluminescence reaction using horseradish peroxidase (POD) or alkaline phosphatase (ALP) in antibody-affinity blotting was developed. The intensity of chemiluminescence obtained by ALP was greater than that by POD; however, the coefficient of variation with POD was less than that with ALP....

Microdetermination of Chloride in Biological Fluids, with Solid Silver Iodate

was outlined in detail, with gasometric measurement of the iodate resulting from the reaction. In this paper titrimetric measurement of the iodate is described. Titrimetric measurement of the iodate is directly applicable to the supernatant fluid in the AgI08 precipitation of chloride from salt solutions, urine, serum, and protein-free jiltrate of serum and of whole blood.’ For the titrimetric ...
