NEB Diluent and Buffer Table

Composition List for NEB Diluents and Buffers

You can find the composition of NEB buffers and diluents in the table below. The columns represent the diluent or buffer referenced, and the rows represent the individual diluent or buffer components. The squares within the table indicate the final concentration of components for a 1X concentration of the buffer or diluent defined by the column. The final row of the table indicates the final pH of the mixture.
