If protein X produces a higher absorbance reading at pH 7 than it does at pH 9, what can you conclude? Question 1 options: A lesser amount of protein X was used in the reaction at pH 7 than at pH 9. A greater amount of protein X was used in the reaction at pH 9 than at pH 7. Protein X is a more efficient catalyst at pH 7 than it is at pH 9. Protein X is a more efficient catalyst at pH 9 than it is at pH 7.
A purified protein fraction has a total sample volume of 360 µL. The sample has a corrected A280 of 0.484, and the blank corrected A280 was 0.052. (Both values were measured with a path length of 1.00 cm.) If 5.00 µL of the sample was used in a reaction, calculate the mass of protein in the reaction (in µg).
