Colorimetric Determination of Serum
In the past few years there has been renewed interest in the study of serum cholinesterase in various disease states, particularly those affecting the liver. Recently, a colorimetric method for the determination of this enzyme in the serum was reported by Ravin, Tsou, and Seligman (1). Their method, simple to perform, is as accurate as the gastrometric technique and more specific than the elect...
متن کاملColorimetric determination of blood arginase.
N EXTENSIVE LITERATURE Ofl arginase activity in tissues and tissue homogenates has accumulated in recent years. Roberts (1) has studied the arginase activity of liver, kidney, and epidermis of the Swiss mouse and of a transplantable squamous cell carcinoma. He found that liver had the greatest activity, followed by carcinoma, epidermis, and kidney. Sano (2) isolated an enzyme from rabbit intest...
متن کاملColorimetric determination of blood lipides.
Extraction-As the oxidation is essentially non-specific, the plasma extract must be as free of non-lipide reducing substances as possible. All solvents should be tested occasionally for reducing residues remaining after evaporation, and redistilled if necessary. Ether should be maintained peroxide-free. The determinations reported here followed a conventional alcohol-ether extraction and subseq...
متن کاملQuantitative colorimetric determination of tryptophan.
The methods currently used for the estimation of tryptophan are based on one of the following principles: Reaction with aldehydes in acid solution (1, Z), with glyoxylic acid (3), with mercury salts and nitrous acid (4,5), by determination after isolation from its mercury salt (6)) or by the use of Marshal’s reagent (7). Of the above mentioned methods, those based on aldehyde reactions and on t...
متن کاملThe Colorimetric Determination of Glucose.
Several new descriptions of colorimetric methods for the determination of blood sugar have been described in recent years (for example, Polis and Sortwell, 1946; Somogyi, 1945; Nelson, 1944; Haslewood and Strookman, 1939). These procedures are all based on the use of alkaline copper reagents and on the production of molybdenum blue by the action of cuprous copper on complex molybdic acid soluti...
