electron microscopy evidence scanning electron microscopy evidence A type of electron microscopy evidence where a focused beam of high-energy electrons is used to generate a variety of signals at the surface of solid specimens. snadendla 2018-03-14T12:44:11Z With a general growth of the recombinant mycobacterial strains resulting in minimal change, the cell morphology was further examined using the scanning electron microscopy (SEM) technique. As shown in Fig. 5B, the cell lengthened when 20 ng/mL tetracycline was added to the medium to induce expression of the antisense mtrA mRNA (right panel). OMP ECO:0007045
