2 The use of Laemmli Sample buffers ensures optimal band resolution when preparing proteins for SDS-PAGE with Tris-glycine-SDS running Laemmli mM Tris-HCl, pH buffer (w/v) glycerol SDS bromophenol blue4x Laemmli mM Tris-HCl, pH buffer (v/v) glycerol LDS bromophenol blue Storage Room temperatureShelf life 2 years from date of manufactureInstructions for Use1. Add Reducing Agent To obtain a final 1x concentration of 355 mM 2-mercaptoethanol2x Laemmli Sample buffer : Add 50 l of 2-mercaptoethanol per 950 Laemmli Sample buffer : Add 100 l of 2-mercaptoethanol per 900 , add dithiothreitol (DTT or Cleland s reagent) to a final 1x concentration of 50 : For best results, do not store Sample buffer with Dilute Sample2x Laemmli Sample buffer : Dilute 1 part Sample with 1 part 2x Laemmli Sample buffer .
