HEPES (4-(2-hydroxyethyl)-1-piperazineethanesulfonic acid) is a zwitterionic sulfonic acid buffering agent. It is one of the twenty Good's buffers . HEPES is widely used in cell culture , largely because it is better at maintaining physiological pH despite changes in carbon dioxide concentration (produced by aerobic respiration ) when compared ...
A buffer solution is a solution where the pH does not change significantly on dilution or if an acid or base ... HEPES, (4-(2-hydroxyethyl)-1-piperazineethanesulfonic ...
HEPPS (EPPS) is a buffering agent used in biology and biochemistry.The pKa of HEPPS is 8.00. It is ones of Good's buffers. [1]Research on mice with Alzheimer's disease-like amyloid beta plaques has shown that HEPPS can cause the plaques to break up, reversing some of the symptoms in the mice.
MOPS (3-(N-morpholino)propanesulfonic acid) is a buffer introduced in the 1960s, one of the twenty Good's buffers. It is a structural analog to MES, [1] and like MES, its structure contains a morpholine ring. HEPES is a similar pH buffering compound that contains a piperazine ring.
A lysis buffer is a buffer solution used for the purpose of breaking open cells for use in molecular biology experiments that analyze ... HEPES - NaOH 7.2 - 8.2 ...
HEPBS (N-(2-Hydroxyethyl)piperazine-N'-(4-butanesulfonic acid)) is a zwitterionic organic chemical buffering agent; one of Good's buffers.HEPBS and HEPES have very similar structures and properties, HEPBS also having an acidity (pK a) in the physiological range (7.6-9.0 useful range).
For this reason, DEPC cannot be used with Tris or HEPES buffers. In contrast, it can be used with phosphate-buffered saline or MOPS. [3] A handy rule is that enzymes or chemicals which have active -O:, -N: or -S: cannot be treated with DEPC to become RNase-free, as DEPC reacts with these species.
