Transformation Math
First Transformation: $$ 10^9\ \frac{\mbox{colony forming units}}{\mu g} * \frac{1\ \mu g}{10^3\ ng} $$
 * 10^{-3}\ \mbox{dilution} * 1\ ng = 10^3 \mbox{colonies}

Second Transformation: $$ 50\ \mbox{colonies} * \frac{\mu g}{10^9\ \mbox{colony forming units}} = 5 \times 10^{-8}\ \mu g $$ $$ \frac{5 \times 10^{-8}\ \mu g}{2\ \mu L} = 2.5 \times 10^{-8} \frac{\mu g}{\mu L} $$

Analysis
E4 Titer: $$1327\ \mbox{plaques} \div 10^{-6}\ \mbox{dilution} = 1.3 \times 10^9$$ M13 Titer: $$276\ \mbox{plaques} \div 10^{-6}\ \mbox{dilution} = 2.8 \times 10^8$$ The E4 Titer was 4.6 times larger than the M13 Titer. The extra glutamic acids on the E4 Phage may allow it to diffuse faster and therefore infect more bacteria.
