GTE stands for Glucose-Tris-EDTA.Glucose is used to maintain osmolarity: 50mM (millimolar) glucose prevents premature cell lysis, which can cause lower DNA yields to due to aggregation and degradation. The other components of the buffer also contribute to the osmolarity of the solution, but glucose, being a non-electrolyte, is a good choice because it does not interfere with the solution's buffer properties. The Tris is used to buffer whatever you're adding this to at pH 7.9. EDTA binds divalent cations like Ca2+ and Mg2+, thereby weakening the cell envelope of cells in the mixture. This is typically used for miniprep/DNA purification, when you have to lyse the cell and get internal cell components out into the solution.
Solutions that resist change in pH when added to a strong acid or base are known as buffer solutions.
A buffer. just got the answer correct on a bio exam
No, it is not a buffer.
The composition of Buffer P2 is:200 mM NaOH1% SDS (w/v)Buffer P2 is the lysis buffer
Water is not a good pH buffer.

The buffer capacity increases as the concentration of the buffer solution increases and is a maximum when the pH is equal to the same value as the pKa of the weak acid in the buffer. A buffer solution is a good buffer in the pH range that is + or - 1 pH unit of the pKa. Beyond that, buffering capacity is minimal.
Glucose is added to increase the osmotic pressure outside the cells.glucose should also be added to maintain osmolarity and prevent the buffer from bursting the cells.
the ozone layer is our buffer zone between the us and the harmfull rays of the sun.
Here is an useful article on foods that are good for manage glucose levels: http://www.livestrong.com/article/311255-good-foods-for-glucose-management/
no
a good title would be glucose levels.
After World War 1, attempts were made between Germany and France to make buffer states.
Yes. Main buffer is HCO3-. The pH of arterial blood plasma is 7.40.
The Soviet Union took over Eastern Europe as a buffer state.I hate it when I have to be the buffer between Georgia and Betty.Proper insulation is not only good to keep your house warm but it is a noise buffer too.
No, NaOH is a strong base and NaCl is the salt of a strong acid and a strong base and so has no acidic or basic properties. A buffer solution requires an acidic or basic salt and the corresponding weak acid or base.
