Continous flow

FIGURE 5.4 Schematic representation of a continous-flow system for the solid-phase synthesis of peptides. Solvent is forced through the system by a pump. The support is in the form of a column that is stationary. A reaction is monitored by measuring the change in absorbance of the solvent stream. [Pg.128]

Dialysis procedures are relatively slow when mass transfer is based only on diffusion. These procedures do not offer particular selectivity when they are concurrently used for extraction and cleanup purposes, because many low-molecular-weight sample components along with the analyte can pass through the membrane. Dialysis systems must be renewed frequently, automation is difficult except for the continous-flow systems, and there is a significant temperature dependence. [Pg.577]

The next step is the preparation of mRNA. Cell-free translation of proteins can be achieved mainly by three different modes—batch (11,12), bilayer (16), and continous-flow cell-free (18). Appropriate volumes of transcription products can be produced depending on the mode of translation. [Pg.137]
