ساخت الکترودهاِی اصلاح شده ِیکِی از چالشهاِی همِیشگِی در دانش شیمِی بوِیژه شیمِی تجزیه مِی باشد ،که با در نظر گرفتن سادگِی ساخت، کاربردی بودن و ارزان بودن روش مِی توان به باارزش بودن چنِین سنسورهاِی پِی برد.آنچه که در ادامه آورده شده به ساخت و کاربرد الکترودهاِی اصلاح شده با استفاده از نانو ذرات در اندازه گِیرِی ولتامترِی آهن وکادمِیم اشاره دارد. کار اول اختصاص دارد به ساخت الکترود خمِیر کربن اصلاح شده با لِیگاند داِ...
15 صفحه اولThe pantothenic acid content of coenzyme A by chick assay.
Lipmann, Kaplan, Novelli, Tuttle, and Guirard (1) reported that, whereas concentrates of the coenzyme required for acetylation (coenzyme A) showed no pantothenic acid activity by the ordinary microbiological assay, considerable amounts of p-alanine were found after acid hydrolysis. From this early observation, it was suspected that the coenzyme might contain combined pantothenic acid which was ...
متن کاملAssay and distribution of bound forms of pantothenic acid.
The distribution of CoA (I), pantetheine (2, 3), and pantothenic acid (4) among a variety of natural materials is well established. However, until now, the relative amounts of these compounds present in any one substance has not been determined. Also, data on the distribution of P-pantothenic1 acid and P-pantetheine, both of which are intermediates in the biosynthesis of CoA (5), is rather meag...
متن کاملAn assay for pantothenic acid in biologic fluids.
ANTOTHENIC ACID DEFICIENCY reduces biologic actylations and leads to a variety of pathologic changes in blood cholesterol partition and antibody production. Deficiency affects particularly the adrenal cortex, nervous system, the skin, and hair; it also affects longevity (1, 2, 3, 4). The ubiquity of pantothenic acid (as suggested by its name), makes it difficult to demonstrate deficiencies, eve...
متن کاملDirect enzymatic assay for %HbA1c in human whole blood samples.
OBJECTIVES Development and validation of a direct enzymatic HbA1c assay that utilizes a single channel on chemistry auto-analyzers without the need to run separate glycated hemoglobin and total hemoglobin assays. DESIGN AND METHODS An enzyme based single channel assay was developed to measure %HbA1c in human whole blood samples. The performance characteristics of the Diazyme Direct Enzymatic ...
