Figure. Evaluation of Anthrax Vaccine Adsorbed (AVA) for amplified mycoplasma DNA by gel electrophoresis. Molecular weight markers were run in lanes 1 and 17. Control samples in lanes 2-5 were mycoplasma broth, Hut 78 cell extract, Acholeplasma laidlawii, and Mycoplasma pirum, respectively. The AVA samples were in lanes 6 to 15: Lot FAV048B from Davis Monthan AFB (lane 6), Kansas City MO NRC (lane 7), and Camp Pendleton (lane 8); Lot FAV047 from Fort Detrick (lanes 9 and 11) and Pearl Harbor NMC (lane 10); Lot FAV031 from Fort Worth Base Naval Clinic (lane 12) and the Pentagon Clinic (lane 13); and Lot FAV008 from Davis Monthan AFB (lane 14) and McEntire ANG Station (lane 15). Lane 16 contained water. Bands seen below 100 base pairs are primer multimers.
