Materials
- BioRad Protein Assay Dye Reagent Concentrate cat#500-0006
- Disposable Plastic Cuvette
Protocol
- Dilute reagent 5X in water, stable for 2-3 weeks
- Pipet 1 mL into disposable plastic cuvette
- Add 1-10 uL of protein sample, cover with parafilm and mix
- Let sit 5-10 min to react
- Set spectrophotometer as follows:
- Go to protein assay then Bradford assay
- Set formula, then select more
- Set b=0.045 (or determine slope)
- Set dilution to be 1/vol (ie 0.1 for 10 uL)
- Blank then measure samples, absorbance must be less than 0.9
- Print (hit Recall, then enter, then print) and attach to experiment
