WebGive a heat shock to the cells by placing the reaction mix at 42°C for 30-90 seconds (water bath or Heat-block). After the heat shock, transfer the cells onto the ice and add 500uL of warm LB. Place the tubes in the shaker (180 rpm) at 37°C for 1 hour. After the incubation, give a brief spin at 4000 rpm for 2-3 minutes and decant the ... Artificial competence can be induced in laboratory procedures that involve making the cell passively permeable to DNA by exposing it to conditions that do not normally occur in nature. Typically the cells are incubated in a solution containing divalent cations (often calcium chloride) under cold conditions, before being exposed to a heat pulse (heat shock). Calcium chloride partially disrupt…
