Abstract

Abstract Image

We are confronted daily to unknown microorganisms that have yet to be characterized, detected, and/or analyzed. We propose, in this study, a multidimensional strategy using polyclonal antibodies, consisting of a novel proteomic tool, the ProteomeLab PF2D, coupled to immunological techniques and mass spectrometry (i-PF2D-MS/MS). To evaluate this strategy, we have applied it to Bacillus subtilis, considered here as our unknown bacterial model.

Keywords: Bacillus subtilis • flagellin • in-gel digest • mass spectrometry • PF2D
