SUMMARY
PHAGE SOLUTION
Titer = x pfu/ml
OR y pfu in z ul
SERIAL DILUTION
Add 100ul (10-1x) phage to 900ul HFB and mix = TUBE #1
Transfer 100ul (10-2x) #1 to 900ul HFB and mix = TUBE #2
Transfer 100ul (10-3x) #2 to 900ul HFB and mix = TUBE #3
and so on...
PLATING
TUBE #1 -> plate 100ul (1/10) -> 10-2x
TUBE #2 -> plate 100ul (1/10) -> 10-3x
TUBE #3 -> plate 100ul (1/10) -> 10-4x
and so on...
MATHS
Count n plaques on plate from 10-7x plate:
x = n * 10-7
OR if z = 200ul (e.g., mutagenesis)
y = (n * 10-7) * z/1000
