This is a first report on estimation of total protein in human albumin solution (for infusion) by Kjeldahl method and is based on the data of 20 specimens of human albumin solution. The method has delivered good results with a sample standard deviation of 0.35. The mean ...
(PER), expressed in terms of weight gain per unit of protein consumed by the test animal in short-term feeding trials. However, still more specific nitrogen balance methods can be applied to evaluate the nutritive quality of a protein. One of these principles is the estimation of the ...
英文名称:Animal feeding stuffs — Determination of nitrogen content and calculation of crude protein content — Part 1: Kjeldahl method 标准状态:现行 发布日期:2005-06-30 文档简介 ISO5983-1:2005规定了如何通过凯氏定氮法测定动物饲料中的氮含量,并由此计算粗蛋白含量。这是一种广泛使用的分析方法,尤其在...
If it is necessary to determine the amount of protein in a mixture of animal foodstuffs, a sample is converted to ammonium salts by boiling with sulfuric acid and a suitable inorganic catalyst, such as copper sulfate (Kjeldahl method). The method is based on the assumption that proteins ...
The Bradford Method for Protein Quantitation A rapid and accurate method for the estimation of protein concentration is essential in many fields of protein study. The Lowry method ( Chapter 1 in vol. 1 of this series) has been widely used, but is susceptible to interference from ... JBW Ham...
Accurate Protein Analysis: The Crude Protein Tester DW8280 utilizes the Kjeldahl method to provide precise protein content analysis, ensuring accurate results for users, such as researchers and quality control specialists. Easy to Use: This electronic tester features a user-friendly interface, making it...
Nitrogen in the supernatant was estimated by the Kjeldahl method (Frias et al., 2011; Singh and Jambunathan, 1981) and nitrogen due to the enzymes and buffer was discounted. Protein digestibility calculated as:Proteindigestibility=nitrogencontentofsupernatantnitrogencontentofthesample×100×6.25 2.3.3...
