You need to load 2mg total protein in 10ml (i.e. final protein concentration needed is 0.2mg/ml for all the samples). You need to prepare 20 ml of this solution that has protein and 1X sample buffer (water is used for dilution). Complete the table below. Sample Protein Concentration mg/mL Protein Sample (microliter) Water (microliter) 4X Sample Buffer (microliter) Total Sample Volume (microliter) Total Lysate (-) 1 mg/mL 20 E1 0.07 mg/mL 20 E2 0.15 mg/mL 20 E3 0.2 mg/mL 20

You find yourself setting up another Western blot, however. today you are preparing the samples to load onto the SDS-PAGE gel. You are using a 4-20%SDS-PAGE gel that can hold a maximum of 30 μしper 1 You remember from you so decided to prepare each sample with a final volume of 25 uL. However, no one is perfect at pipetting, so make sure each sample is made at 1.5X the total volume needed per well. The protein you are interested...
