Laemmli SDS sample buffer, non-reducing (4X)

Chemical Properties

Fully miscible.


Laemmli SDS sample buffer is used for protein sample preparation to be used in the Laemmli SDS-PAGE system, The SDS detergent denatures the proteins and subunits and gives each an overall negative charge so that each will separate based on size. The bromophenol blue serves as a dye front that runs ahead of the proteins and also serves to make it easier to see the sample during loading.


Contains 250mM Tris-HCl (pH 6.8), 8% SDS, 40% glycerol, and 0.02% bromophenol blue.
