Figure Lengend Snippet: a-c , One ( a ), two ( b ) and three ( c ) Duracell or Energizer alkaline AAA batteries were used, each providing around 1.5 volts. d , One Duracell or Energizer lithium button cell CR2032 provides about 3 volts. e-f , Four Duracell or Energizer alkaline AA ( e ) and AAA ( f ) batteries provide around 6 volts. g , A Belkin power bank whose universal USB-A 2.4 A port delivers up to 5 volts. h , Apple and Huawei mobile phone chargers. The charger was directly plugged into mains electricity and the charger wires were cut for connection to the electrodes submerged in the culture medium. i , One Duracell or Energizer 12 volt 23 amp alkaline battery. j , Two Duracell or Energizer 9 volt block alkaline batteries. k , Two Duracell or Energizer 12 volt 23 A alkaline batteries. l , Two A220/504 A Exell batteries provide around 30 volts. SEAP levels in supernatants of culture medium were measured at 24 h after electrostimulation for the indicated time. Columns each represent the mean ± SD of the four indicated data points. P values were calculated between stimulated and non-stimulated group.
Article Snippet: Fig. 3 SEAP expression by DART-engineered cells stimulated for the indicated time periods with various DC supplies. a – c , One ( a ), two ( b ) and three ( c ) Duracell or Energizer alkaline 1.5 V AA batteries. d , Two Duracell or Energizer lithium button cells (CR2032) provide about 6 V. e , One Duracell or Energizer 9 V block alkaline battery. f , One A220/504 A Exell battery.
