About this item

This product contains 8% SDS, 40% glycerol, 0.02% bromophenol blue and 0.25 M Tris HCl, pH approx. 6.8. Does not contain 2-Mercaptoethanol.

SDS-PAGE Sample Buffer is specially formulated for protein sample preparation based on the Laemmli Method of SDS-PAGE system.

Preparation of non-reducing sample
A protein sample is mixed with the 4X SDS-PAGE sample buffer (3:1). If necessary, heating the mix solution and then cool down the tube at room temperature. The solution is ready for SDS-PAGE.

Preparation of reducing sample (reducing with 2-Mercaptoethanol)
Add 20 μl of 2-Mercaptoethanol per 80 μl of 4X SDS-PAGE sample buffer. Mix thoroughly. Then a protein sample is mixed with the sample buffer (3:1) and heating to 95 - 100 °C for 5 min. Cool down the tube at room temperature. The solution is ready for SDS-PAGE.
Reducing reagents: 2-Mercaptoethanol [for Electrophoresis], DL-Dithiothreitol [for Electrophoresis], etc.

Caution: Note: Dissolve the precipitation at 25 - 30 °C if precipitation occurs during storage.
