(57) [Summary] [Purpose] To provide a highly useful staining reagent which has excellent visibility of formed substances in a sample and does not cause aggregation of lysates such as proteins, sugars and glycoproteins in the sample. [Structure] About 0.2 to 10.0 × 1/10 2 mol / l Evans -1 capacity and about 0.2-10.0 × 1 / 10 2 mol / l erythrosine (about 0.5 to 2.0 volume) is mixed, and sodium azide or para-hydroxyphenylacetic acid or dehydro is added to the mixed solution to a concentration of about 0.01 to 1.0%. Add either acetic acid or ethylenediaminetetrasulfuric acid and use as solvent 1 / Using 30 to 1/5 mol / l phosphoric acid solution, succinic acid solution, or tris acid solution, the pH is 5.7 to It is designed to be 7.9. |
