Buffering agents and Buffers

WebTools. A chaotropic agent is a molecule in water solution that can disrupt the hydrogen bonding network between water molecules (i.e. exerts chaotropic activity ). This has an effect on the stability of the native state of other molecules in the solution, mainly macromolecules ( proteins, nucleic acids) by weakening the hydrophobic effect. WebFor example, if you prepare a Tris buffer at pH 7.0 at 4.0°C and perform a reaction in that same buffer at 37°C, the pH will drop to 5.95. If you have a Tris buffer prepared at 20°C with a pK a of 8.3, it would be an effective buffer for many biochemical reactions (pH 7.3–9.3), but the same Tris buffer used at 4°C becomes a poor buffer at ... jang hip resurfacing
