QUESTION 17 A student wanted to run a protein sample on a SDS PAGE gel, and in the process of casting a gel the student had forgotten to add the stacking layer on top of the resolving layer of the gel. What problems would likely arise as a result of this mishap? Proteins would migrate much faster through the gel Proteins would not be able to migrate through the resolving layer and stays at the top of the gel Proteins will move into the resolving layer at different times and this would result in a smear on the gel O There is no problem, proteins in the sample would resolve the same as if they were ran on a SDS PAGE gel with a stacking layer on top of a resolving layer

Solution B is diluted by adding 50 uL of solution B to 300 uL of buffer. The absorbance of sample C is 0.05. What is the concentration of sample A assuming the following parameters. |=1 cm Molar extinction coefficient = 10 M-1 cm-1 O 0.7 M O 0.8 M O 0.9 M O 1.0 M
