Overview
One of the strongest way for lineage tracing on sections is to use biotin dextran amine. For example, fluoresceine or Texas-Red Dextran amines are used by many people. However, as you know, fluoresceine is temporary. lacZ staining is very good for whole embryos but not so nice on section. This method using Biotin dextran amine can very easily provide you with permanent and very strong staining on sections
