4X LDS Sample Buffer

4X LDS Sample Buffer is used to prepare protein samples for denaturing polyacrylamide gel electrophoresis (PAGE) with SurePAGE™, ExpressPlus™ and most other types of Bis-Tris gels. LDS sample buffer contains lithium dodecyl sulfate with pH at 8.4, which helps reducing the disulfide bonds and ensure optimal protein separation.
