Buffers
Buffers are substances that prevent the pH of a solution from changing. They do this by either accepting hydrogen ions if the solution becomes acidic or by releasing hydrogen ions if the solution becomes basic.
Buffers are solutions that have the capacity withstand the addition of small amounts of protons and/or hydroxide ions, or undergo dilution, without a dramatic change in pH.

The episodic buffer is dedicated to linking information across domains to form integrated units of visual, spatial, and verbal information and chronological ordering (e.g., the memory of a story or a movie scene).
The salts and buffers necessary as reagents for the PCR act as interferences for the MALDI process, and therefore must be removed prior to MALDI-MS analysis.
Mitochondrial dysfunction may be linked to neurodegenerative diseases through a variety of different pathways, including free-radical generation, impaired calcium buffering and the mitochondrial permeability transition.
The radioactive hexasaccharide — dissolved in a suitable buffer — is placed in the front chamber ("F").
Serum from a nonimmune animal (e.g., a rabbit) is placed in the back chamber ("B").
The current consensus among paleontologists is that large populations are buffered against evolutionary change by natural selection or genetic drift. Evolutionary change becomes easier when populations split into smaller demes.
Putting in a biosphere reserve often involves having a nuclear area, where humans are not allowed to disturb the nature of the biodiversity that's there, and then having a buffer zone around that region where humans are able to use resources to help ...
The electrolyte may be continuous (a single buffer) or discontinuous, where a sample is stacked by means of a buffer discontinuity, before it enters the running gel/ running buffer.
Make sure the reaction is free of any organic solvents such as alcohols which might be present in the DNA preparation.
Raise the ionic strength of the reaction buffer to 100-150 mM (provided the enzyme is not inhibited by high salt).
AGAROSE GEL ELECTROPHORESIS - A method for separating nucleic acids (DNA or RNA) within a gel made of agarose in a suitable buffer under the influence of an electrical field.
Hidden within these biomes are potential medicines and many thousands of unseen and undiscovered species. Also, forests have a global climate-buffering capacity, so their destruction may cause large-scale changes in global climate.
Plasma has 90% water and 10% dissolved materials including proteins, glucose, ions, hormones, and gases. It acts as a buffer, maintaining pH near 7.4. Plasma contains nutrients, wastes, salts, proteins, etc.
