A researcher consistently detects no signal for their protein of interest despite using a validated primary antibody at the manufacturer’s recommended concentration. Western blot of a positive control lysate shows strong signal. Which of the following is the MOST likely explanation?

For affinity purification of a protein from a bacterial lysate, which of the following collections would you expect to see the highest concentration of your desired (tagged) protein?

You are picking reagents for a 5-color flow cytometry experiment. Without considering the expression level of the targets in the experiment or the brightness of the fluorochromes, only based on the distribution of the colors which combination of fluorophores would you pick?   A B

You have stained cells for a flow cytometry experiment with an anti CD62L -APC antibody. Plotting the APC fluorescence you observe 3 populations. If the blue line represents an unstained control sample, what description of the populations labeled 1, 2 and 3 would be appropriate?
