Enzyme-linked immunosorbent assay (ELISA):

Samples were grown overnight in LB-L media, then subcultured 1:100 in LB-L media and grown for 8 h at 37 C and 225 rpm. The cultures were pelleted by one centrifugation step of 2272g for 10 min and the supernatant was passed through a 0.45 m filter. The wells of a 96-well microtiter plate (Santa Cruz Biotechnology, Inc., part# sc-204463) was coated with 100 L of a solution of 4 g mL¹ protective antigen (PA) of the anthrax toxin (List Biological Laboratories, part# 171E) in 5 mM HEPES, 50 mM NaCl, pH 7.5 covered at 4 C overnight. Liquid was removed by inversion and wells were incubated with a 200 L blocking solution (200 L 2% milk, 0.05% TBST) at room temperature for 1 h. …
