简介：
Overview
Translating ribosome affinity purification (TRAP) enables the investigation of developmental processes at a cellular level with minimal tissue processing. This technique utilizes a GFP-labeled ribosomal subunit to isolate high-quality RNA, which can then be analyzed for specific expression profiles.
