일반 설명
Ninhydrin reagent is mostly used for the detection of amino acids. It basically gives a characteristic purple color on reaction with a-amino acids and other amino compounds, provided the pH of the reaction is 5.0 or higher. At an acid pH of 0.3, the reaction of ninhydrin with ornithinine and proline results in a red color product. Ninhydrin reagent can stay stable at room temperature in the absence of nitrogen atmosphere for upto 1 month in the ethylene glycol-sodium acetate solvent system.
애플리케이션
1 g ninhydrin dissolved in 475 mL 1-butanol and 25 mL acetic acid
Ninhydrin reagent may be used for the quantitative determination of total protein content in tissue hydrolysates.

1. An acid ninhydrin reagent was found to react specifically in forming a pink product (E(max.) 560mmu) with cysteine. 2. The method was highly sensitive for the determination of cysteine (in 28.0x10(3)). Homocysteine, glutathione, proline, ornithine and other naturally occurring

A novel, aerobic, Gram-stain-negative, non-motile, non-spore forming, rod-shaped bacterium, designated strain Dol 15-39T, was isolated from a seawater sample near Geoje Island in the South Sea, Republic of Korea. The strain was found to be oxidase-negative and catalase-positive. The isolate
