【0015】
本発明の総蛋白質の定量方法においては、まず最初に銅イオンを含む第1試薬と検体を反応させた後にアルカリ溶液を含む第2試薬と反応させる。銅イオンを含む試薬としては、本発明の目的に適合するものであれば全て用いることが出来る。例えば、硫酸銅溶液、塩化銅溶液、硝酸銅溶液などが例示される。銅イオンの反応液中での最終濃度は通常、例えば硫酸銅を使用した場合3〜30mM、好ましくは6〜20mM程度である。該溶液はpHが10〜13であることが好ましい。実施例1および2(図1および2)に示すようにpHを10以上にすることによりヘモグロビン色素、ヘモグロビン蛋白質およびBSPのようなアルカリ側で発色する色素の干渉を回避することができる。しかしながらpHが13よりも高くなると蛋白質が発色し、測定が妨害される。
[0015]
In a quantitative method of total protein of the present invention causes firstly reacted with a second reagent containing an alkaline solution after the reaction of the first reagent and the specimen containing copper ions. Any copper ion-containing reagent may be used as long as it meets the purpose of the present invention. For example, a copper sulfate solution, a copper chloride solution, a copper nitrate solution, etc. are illustrated. The final concentration of copper ions in the reaction solution is usually, for example, about 3 to 30 mM, preferably about 6 to 20 mM, when copper sulfate is used. The solution preferably has a pH of 10-13. By setting the pH to 10 or more as shown in Examples 1 and 2 (FIGS. 1 and 2), it is possible to avoid the interference of dyes that develop on the alkali side such as hemoglobin dyes, hemoglobin proteins and BSP. However, when the pH is higher than 13, the protein is colored and the measurement is interrupted.

【発明の効果】
本発明の総蛋白質測定用キットは特定の2試薬を用いて測定を行うので検体盲検の必要性がなくなり、乳びおよび溶血の干渉を回避することができる。はじめに加える第1液状試薬に銅イオンを添加することにより、ビリルビンの干渉、ビウレット反応陽性物質であるアミノ酸、糖類、クレアチニンなどの影響を回避することができる。さらにはじめに加える第1液状試薬のpHを10〜13に調製することによりヘモグロビン蛋白やBSPなどのアルカリ側で発色する物質の影響も受けない。
また、後で加える第2液状試薬であるアルカリ溶液を水酸化リチウムで調製することにより少ないアルカリ量で感度良く測定できるため粘度を低く抑えることができ、分注時の誤差による再現性の低下が抑えられる。また使用するアルカリ溶液が少量ですむため廃液処理が容易で安全な試薬を供給できる
[0029]
【Effect of the invention】
Since the kit for total protein measurement of the present invention performs measurement using two specific reagents, the need for sample blinding is eliminated, and interference with chyle and hemolysis can be avoided. By adding copper ions to the first liquid reagent to be added at the beginning, the effects of bilirubin interference, amino acids which are biuret reaction positive substances, saccharides, creatinine and the like can be avoided. Furthermore, by adjusting the pH of the first liquid reagent to be added to 10 to 10 to 13, it is not affected by substances that develop color on the alkali side, such as hemoglobin protein and BSP.
In addition, by preparing an alkaline solution, which is a second liquid reagent to be added later, with lithium hydroxide, it is possible to measure with a small amount of alkali with high sensitivity, so the viscosity can be suppressed low, and the reproducibility decreases due to errors in dispensing. It is suppressed. In addition, since a small amount of alkaline solution is used, waste liquid treatment is easy and safe reagents can be supplied .
