采用 TLC法对淀粉活化酶进行成品分析
Authors:  Darrell Cockburn and Nicole Koropatkin, date: 10/20/2015, view: 10843, Q&A: 1
Thin layer chromatography (TLC) is a useful technique for detecting the presence of monosaccharides through to oligosaccharides, though it needs to be optimized for the specific sugars that are analyzed. Here we present a method for visualizing the ...
