Washed vs Unwashed

USA300 LAC biofilm washed or not washed with ammonium formate (150 mM) prior to matrix deposition. Replicate data are averaged of 1000 laser shots each, collected on serial sections of a biofilm.

USA300 LAC生物被膜（biofilm）在基质沉积前经150 mM甲酸铵洗涤或未作洗涤处理。每份重复数据均为采集自该生物被膜连续切片的1000次激光轰击结果的平均值。
