Biotin-12 SE is an amine-reactive biotin derivative with a long spacer group. It is useful for making biotin labeled nucleoside triphosphates among other applications.
EDC (or EDAC) (1-(3-Dimethylaminopropyl-3-ethylcarbodiimide, hydrochloride)) has recently been found to be very useful for fixing in situ chelators, including the fluorescent ion indicators for histological studies following physiological experiments. EDC is also a widely used reagent to activate carboxy groups for amine coupling.
