A simultaneous two-colour detection method of human IgG- and IgE-reactive proteins from lactic acid bacteria

J Microbiol Methods. 2016 Jul:126:72-5. doi: 10.1016/j.mimet.2016.05.007. Epub 2016 May 13.

Abstract

Whole cell extracts of two Lactobacillus strains were tested with primary antibodies from two pooled sera from allergic patients. Fluorescently labelled anti-human IgG and anti-human IgE secondary antibodies applied in Western blotting, together with an appropriate image acquisition protocol facilitated imagining bacterial proteins that reacted with human IgG and IgE.

Keywords: Bacterial proteins; Human serum; IgE; IgG; Immunoreactivity; Lactobacillus.
