E. coli labeling using SYBR Green I and YOYO-1

Objective

  • To confirm the bacteria staining with revised procedures
    • Using FITC filter, 20X objective, No cover slip
  • The stained bacteria will be used for microwell application


Material and Samples

  • Samples: Diluted E. coli, 10^6 CFU/uL (stored in PBS, 4C)
  • YOYO®-1 iodide (491/509) - 1 mM solution in DMSO
  • Diluted SYBR Green I (diluted in H2O, stored in 4C)


Procedures

  • Drop 1 uL of E. coli on the glass slide
  • Mix the E. coli with either 10 uL 2X SYBR Green I or 2 uL of YOYo-1 dye, gently pipeting for mixing
  • Leave the slide in dark box (slide storage box)
