Objective
- Run a Bradford Assay to measure protein concentration of BSA
Description
- prepared 50 mL of stock solution of BSA, 5 mg in 5 mL of saline
- recorded UV-VIS spectra between 200 nm and 800 nm
- Made 6 standard solutions (1 mL each) between 1 μg/mL and 20 μg/mL
- included stock solution, 200 μL of the Bio-Rad Protein Assay reagent, and Tris/NaCl buffer in microcentrifuge tubes
- tubes were vortexed and left to sit for 5 mins
- UV-vis spectrum measurements (between 400-800nm) were obtained for solutions within hour of their preparation
- duplicate blanks solutions (1ml of Tris/NaCl buffer, 200 μL Bradford reagent, 800 μL buffer) were made and UV-vis spectrum measured
