Does the IR spectroscopy align with the product below and if so why?
Applying the best-fit method you produce the following plot. Please select the correct statement. Group of answer choices: 1. The Bradford assay gives a hyperbolic plot for absorbance versus protein concentration. 2. The Bradford assay is measured at at absorbance of 600 nm 3. Within a range of relatively low protein concentrations, the hyperbolic curve can be approximated reasonably well by a straight line.
