Mixing LDS Sample Loading Buffer with protein samples denatures and reduces the proteins due to lithium dodecyl sulfate and 2-mercaptoethanol content. The buffer’s pH of 8.4 allows for maximum activity of the reducing agent. Glycerol is included in the loading buffer as a density agent to ensure the samples sink into the sample wells, while Coomassie® Brilliant Blue serves as a tracking dye to monitor the progression of electrophoresis.
