Plaque Assay for MEL X Plaque 11/28/18
Rationale: Results for the second plaque assay from MEL 2 did not show any plaques so perform a plaque assay for a new plaque picked from Melissa’s plate labeled MEL X
Process:
- washed table and setup aseptic zone
- picked plaque and swirled it in 50 µL phage buffer (MEL X plaque lysate)
- Made LB agar media for 3 plates
- 6 mL LB broth
- 68 µL 1 M CaCl2
- 7.5 mL 2X TA
- added 50 µL lysate (Mel X plaque) to 0.5 mL arthro and let sit for 15 minutes
- Poured control plate with ~5mL from the LB agar media
- Added arthro lysate mixture to LB agar media
- Poured plate from tube and let sit for ~15 minutes
- Incubated for 48 hours at 28 degrees Celsius
Next Steps: Another plaque assay but with alterations to get a higher titer.
