Beta-mercaptoethanol

Beta-mercaptoethanol is a chemical reductant that is used to distrupt protein quaternary and tertiary structure, often for SDS-PAGE. Although not generally written on the label- the stock purchased from Sigma is 12M. In can be found in the door of Fridge 1 in the Weis lab. It smells terrible- so don't spill it. Here is the MSDS.
