Figure 3From: Highly specific fiber optic immunosensor coupled with immunomagnetic separation for detection of low levels of Listeria monocytogenes and L. ivanoviiWestern blot showing reaction of MAb-3F8 with cell wall proteins from (a) Listeria spp. and (b) serotypes of L. monocytogenes . Proteins were resolved by SDS-PAGE (15 %) before immunoblotting. MAb-3F8 reactive protein (p30) is a 30-kDa protein present in all Listeria spp.Back to article page
