A student weighed out 0.150 g of protein powder and dissolved it in 100 mL of water (Solution 1). The student then diluted this solution by transferring 1 mL into a 25 mL flask and diluting with water (Solution 2). Finally, 1 mL of that solution was transferred to a test tube and combined with 4 mL Bradford reagent. The absorbance of the solution in the test tube was 0.187. Assuming that the best fit linear line of the standard curve was y = 0.04144 x + 0.01521 (μ g mL), calculate the percent protein by mass in the original protein powder.

Mass spectrometry X-ray diffraction Both techniques Answer Bank protein may be denatured small amounts of protein are sufficient can detect a covalent modification to a protein requires a large amount of protein analysis requires information about the protein-coding gene or genes protein sample must be pure protein must be conformationally stable Mass Spectrometry and x-ray diffraction are common biochemical techniques for characterizing proteins. Classify each statement based on whether it applies to MS, X-Ray, or both.
A solution of DNA of unknown concentration (termed "[unknown] DNA solution") gave an absorbance value of 0.39 at 260 nm. The goal here is to determine the DNA concentration of this [unknown] DNA solution. To calculate this, you are given the following additional information: A DNA solution whose concentration is 50 ug/ml has an absorbance value of 1.0 at 260 nm. Using this information and knowing that A1/C1 = A2/C2 i. Calculate the DNA concentration (ug/mL) in the DNA solution of [unknown] ii. iii. iv. Once you have determined the DNA concentration of [unknown] DNA solution, calculate how many ug of DNA would be present in 25 μl of this DNA solution If you dilute the "[unknown] DNA solution" 10-fold, i.e. 1/10, what will the absorbance value (at 260 nm) of the diluted solution be? What will the new concentration of DNA of the diluted solution be?
