3HB assay

This experiment completes the cycle of PHB bioplastic recycling.

The well setup was as shown below:

We prepared serveral dilutions of the samples and measured the absorbance at 445, 450 and 455.

We corrected the absorbance values busubstracting the 0 standard.

We plotted the standard curve and used the below formula to calculate the 3HB concentrations in our samples.

We have taken the dynamic range of the assay into account (according to protocol) and therefore excluded readings where the concentration of 3HB in the well was above 1 mM because these are not accurate.
