Ambion has recently introduced the MessageAmp II bacterial kit, which enables whole genome expression analysis from limited bacterial samples.

According to the company, by amplifying RNA, microarray analyses can be performed with the MessageAmp II kit with up to 500-fold less starting material. The kit can be used with any bacterial species and is compatible with purified total RNA, bacterial mRNA enriched using Ambion’s MicrobExpress kit, or bacterial RNA enriched from host cell mixtures with the MicrobEnrich kit.
