Step-by-Step Guide for Proper Usage of the Pageruler Prestained Protein Ladder

1. Begin by selecting the correct ladder concentration for your experimental needs – The Pageruler Prestained Protein Ladder is offered in a range of concentrations, from 0.5 to 6 mg/mL, to fit different molecular weight ranges and experiment types. To select the appropriate ladder for your experiment, you need to review the molecular weight markers and total number of bands provided for each ladder type.

2. Prepare samples for loading – To prepare each sample for loading onto the gel, thoroughly mix sample composition with a compatible running buffer or sample buffer solution (e.g., Tris–Glycine or SDS). For best results, use 2-4 μL for the highest band intensity during electrophoresis.

3. Load and run electrophoresis – First, load 5-6 μL of proper Pageruler Prestained Protein Ladder into one well of an agarose gel already laid out in a casting stand with an included marker dye solution as a reference point and run at 100 V until bromophenol blue has travelled all the way through the gel (typically 1-2 hours). Then add appropriate samples that have been mixed in either running buffer or sample buffer solution on separate wells in neat rows across the gel with each row no more than 8 wells wide; again run at 100 V until bromophenol blue has traveled all the way through the gel (typically 1-2 hours). When using preparatory gels prior to transfer, it is recommended to set up a reference lane along with any other samples being loaded onto the preparatory gels so as to compare post transfer/staining/imaging results with their initial loading positions on the preparatory gels. Note: The Pageruler Prestained Protein Ladder can also be used directly on Western blots without prerunning electrophoresis gels prior to transfer if desired.
