ZWITTERIONIC NON-DETERGENT SULFOBETAINES
Non-detergent Sulfobetaines Although not detergents, these reagents possess hydrophilic groups similar to
those of zwitterionic detergents but with
-4
When selecting a detergent, the first consideration is
usually the ionic form of the hydrophilic group, which is
either ionic, zwitterionic, or non-ionic. Ionic detergents
typically modify protein
analysis. This new detergent should be a useful
and powerful protein extraction tool in a variety of pro-
teomic applications.

Zwitterionic Detergents
Zwitterionic detergents are unique in that they offer the combined properties of
ionic and non-ionic detergents. Like non-ionic detergents the zwittergents
monitoring of
detergent removal efficiency can ensure that a sample
is sufficiently free of detergents to enable successful
downstream analysis.

2-mercaptoethanol. In addition, detergents such as
Triton X-100, n-octylglucoside, or zwitterionic
detergents have no influence on the enzyme activity.
