Abstract
Phenotypes observed for certain Moraxella catarrhalis wild-type strains or mutants may be caused by a variety of factors including alteration of outer membrane protein composition. Examination of the outer membrane protein profiles may be a valuable tool to identify changes in outer membrane compositions of these strains. Here we describe a method to isolate and analyse M. catarrhalis fractions highly enriched for membrane proteins.
