MOPS stands for 3-(N-morpholino) propanesulfonic acid, and with a pKa of 7.20, makes a good buffering agent for many biological systems requiring neutral pH.HEPES is a chemically similar pH buffering compound. Using proprietary techniques, Tris-MOPS-SDS Running Buffer Powder are made to have long shelf life, high resolution, fast electrophoresis, smaller volume. The running buffer ions are Tris+, MOPS-/MES-, and dodecylsulfate (-) (pH 7.3-7.7). Buffers are stable for 6 months when stored at 4°C. Do not use acid or base to adjust the pH. Each time before use, add fresh Sodium bisulfite to a final concentration of 5 mM from a 1M stock. Reconstitute with 1000 ml H2O to make 1X running buffer per bag of powder. The pH listed for each buffer is for the 1X solution. Load Sample Load the appropriate concentration of your protein sample on the gel.
