Total RNA Extraction from Grape Berry Skin for Quantitative Reverse Transcription PCR and Microarray Analysis

Abstract

Extraction of high quality RNA is an essential step for quantitative reverse transcription PCR (qRT-PCR) and microarray analysis. However, it is not easy to extract high quality RNA from fruit materials, which contain high amounts of polysaccharides, lipids and secondary metabolites. Wan and Wilkins (1994) had developed ‘Hot Borate Method’ to isolate high quality RNA. Here, we describe a modified protocol of the ‘Hot Borate Method’ to isolate high quality RNA from grape berry skin for qRT-PCR and microarray analysis (Suzuki et al., 2015a; Suzuki et al., 2015b).
