To denature, use a loading buffer with the anionic detergent SDS, and boil the mixture at 100°C for 5 min. Unless otherwise required by the experiment, boil each cell lysate in sample buffer at 100°C for 5 min to reduce and denature the sample. The newly introduced 4x Laemmli sample buffer enables the detection of dilute samples by effectively increasing the sample load volume by 50%. It can also be made at 4X and 6X strength to minimize dilution of the samples. NuPAGE LDS Sample Buffer (4X) is used to prepare protein samples for denaturing gel electrophoresis with Bis-Tris or Tris-Acetate gels. Glycerol allows protein to stay inside the well, and the dye bromophenol blue helps track the protein movement.
