产品名称

按照 Stahl 方法的茚三酮试剂, for TLC derivatization

form

liquid

technique(s)

thin layer chromatography (TLC): suitable

impurities

1-butanol
acetic acid

density

0.823 g/mL at 20 °C

Quality Level

Application

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.

General description

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.

Quantitation of small tissue samples for total protein content is essential for many biochemical analyses. In this study a ninhydrin method for measuring the total protein content of tissue hydrolysates is presented. The ninhydrin reagent is stable at room temperature

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
