Figure 2From: Cloning and expression of a novel lactococcal aggregation factor from Lactococcus lactis subsp. lactis BGKP1SDS-PAGE of cell-surface proteins isolated from L. lactis subsp. lactis BGKP1 and BGKP1-20. Lane 1. BGKP1 Agg+; Lane 2. BGKP1-20 Agg- derivative; Lane 3. Molecular marker - protein ladder from 10 to 200 kDa (Fermentas, Vilnius, Lithuania). Arrow indicates high molecular-mass protein band present only in Agg+ strain.Back to article page
