The fungal metabolite brefeldin A (BFA) has multiple targets in cells and has proven valuable for dissecting the cellular processes, including vesicle formation and kinesin distribution, involved in exporting newly synthesized proteins.
Penicillin-binding proteins, present on the cytoplasmic membranes of eubacteria, can be detected with BOCILLIN FL penicillin and BOCILLIN 650/665 penicillin.
