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.

Why is the IR of 4-Methylphenyl 4-bromobenzoate and not 4-bromobenzoic acid? In the IR does it have a presence of both and is there some 4-Dimethylaminopyridine present in the IR?
