2.2. Bacterial CW Preparation and Anthrax Toxin:

An avirulent B. anthracis strain SNKE-FF-E308D was used for CW preparation. After growth, the CW was prepared according to Medvedevs protocol [17]. The amount of CW ranged between 30 and 35% of the dry weight. The CW preparations were checked for aerobic and anaerobic bacteria, endotoxin, and LPS contamination. Bacterial contamination was checked using various growth media. The endotoxin and LPS were tested using a Limulus amoebocyte lysate test kit (E-TOXATE, Sigma, St. Louis, MO, USA). No endotoxin and LPS were found in the preparations. PA, LF, and EF were purchased from List Biologicals Inc. (Campbell, CA, USA). The activity of LeTx was determined by its cytolytic effect on murine macrophage cells RAW264.7. …
