The purpose of this lab is to use Bradford Assay to measure AuNP fiber degradation from a solution of 1nM a-chymotrypsin protease
7 samples of AuNP fibers were spun down at 300rpm for 10 minutes.These fibers will be used for our 23 hours, 120min, 90min, 60min, and 30min samples. A 1:200 dilution of our stock protease was made in Tris buffer. We pipetted 5µL of our 43.539µM stock solution of a-chymotrypsin into 995µL of Tris buffer. This brought the final concentration of the a-chymotrypsin to 0.20506µM. 4.88µL of the diluted a-chymotrypsin (in Tris) and 995.12µL of Tris buffer was added to each sample tube and a blank Eppindorf tube (no fibers), making the final solution 1nM a-chymotrypsin.
A full lab procedure can be found in Nicole Bonan's notebook entry for today
Absorbance for each cuvette was measure via UV-Vis between the emission sprectrum of 400-800nm, and the data is recorded below
