Crocin Extraction

To accurately verify that our construct is indeed producing zeaxanthin, spectrophotometry must be used to characterize our biobrick part. To this end, we tested crocin in two different solvents, along with our Z^2 construct, compared to the absorption spectrum of zeaxanthin in hexane.

This indicates that our Z^2 construct isn't actually producing crocin, or if it is, the crocin isn't expressed highly enough to absorb significantly.
