Approaches to bacterial RNA isolation and purification for microarray analysis of Escherichia coli K1 interaction with human brain microvascular endothelial cells.

Abstract

We established a protocol for isolation of microarray-grade bacterial RNA from Escherichia coli K1 interacting with human brain microvascular endothelial cells. The extracted RNA was free of human RNA contamination. More importantly, microarray analysis demonstrated that no bias was introduced in the gene expression pattern during the RNA isolation… (More)
