Abstract

Quick Oil Red O staining is a well established method to assay total lipid levels in Caenorhabditis elegans , but the software to clean up and analyse the images is either laborious, expensive or both. We have developed a process that uses an existing protocol to stain the animals, followed by Magic Select in Paint3D to remove background and then a custom script in Biopython to quantify average pixel intensity per animal. The software is free, accessible and relatively easy to use for undergraduate researchers.

快速油红 O 染色是检测秀丽隐杆线虫总脂质水平的一种成熟方法,但清理和分析图像的软件要么费力,要么昂贵,要么两者兼而有之。我们开发了一套流程,使用现有的方案对动物进行染色,然后用 Paint3D 中的 Magic Select 去除背景,再用 Biopython 中的自定义脚本量化每只动物的平均像素强度。该软件免费、易用,对于本科生研究人员来说相对容易使用。
