Re: detergents in antibody diuents
|From:||Karen Larison <email@example.com>|
For detergents to be effective, they should be used at their critical
micelle concentration. This is the concentration at which the
detergent forms spherical aggregates with the fatty tails inside the
sphere and the hydrophilic portion on the outside. The Sigma catalog
provides a table of critical micelle concentrations in millimolar
concentrations. You'll have to translate these into % concentrations.
