4X Protein Sample Loading Buffer is optimized for use as a loading buffer for protein gel electrophoresis. This orange loading buffer is recommended for use with Odyssey® Imaging Systems as it does not fluoresce in the 700nm channel the way blue loading buffers do. The buffer is optimized for use with SDS-PAGE and Tris-Glycine-SDS running buffer.
The 4X Protein Sample Loading Buffer and PVDF Membrane Kit comes with 1 roll of Immobilon®-FL PVDF Membrane and 1 bottle of 4X Protein Sample Loading Buffer, 15 mL.
