Abstract

Reverse transcriptase quantitative PCR (RT qPCR) is widely used for assessing the levels of expression of specific genes in various organisms. Here we describe a RT qPCR assay designed to determine the level of expression of fHbp in multiple isolates of Neisseria meningitidis. The level of expression is measured by a two-step qPCR and is associated with a promoter region analysis.
