IFKine™ conjugates for multiple immunofluorescence labelling

IFKine™ conjugated secondary antibodies have improved brightness, photostability and less unspecific background staining. Antibodies are raised in donkey and preadsorbed against serum of other species, which makes them predestined for fluorescence staining, especially for fluorescence multiple labelling.

IFKine™ fluorescence secondary antibodies are highly specific and are not prone for unspecific hybridization with other samples. As a result, up to three different antigens can be detected at the same time with a common immunofluorecence microscope.

IFKine™ innovative fluorophore

IFkine™ fluorophores are a new generation of unique fluorescent dyes, which allow the aquisiton of brighter and more stable fluorescence results. In multiple staining experiments, they exert better effects compared to other commercially available dyes (see table).

Unique donkey host source

IFKine™ secondary antibodies raised in donkey are compatible with most primary antibodies and are therefore especially suitable for multi-staining experiments. In addition, serum from one single species (donkey) can be used to for blocking,  avoiding complicated and time-consuming additional blocking steps. This eliminates any potential obstacles, usually caused by usage of different secondary antibodies species in on single staining experiment.

Minimum nonspecific binding with samples

IFKine™ secondary antibodies specifically recognize IgG from rabbit, mouse and goat, and are preadsorbed against many other species, such as human, rat or mouse. Experiments demonstrate that these secondary antibodies have almost no cross-reactions with other serum proteins, avoiding any nonspecific binding with samples.
