Sds protein complex

SDS-PAGE is an electrophoresis method that allows protein separation by mass. The medium (also referred to as ′matrix′) is a polyacrylamide-based discontinuous gel. The polyacrylamide-gel is typically sandwiched between two glass plates in a slab gel. Although tube gels (in glass cylinders) were used historically, they were rapidly made obsolete with the invention of the more co… Webb13 aug. 2015 · SDS PAGE or Sodium Dodecyl Sulfate Polyacrylamide Gel Electrophoresis is an analytical tool widely used to analyze protein mixtures qualitatively as well as quantitatively. However, we can also use it to determine the molecular weight of an unknown protein using the SDS PAGE protocol.
