HuCAL Fab-F-Spy2-H negative control, clone AbD18705ad is a recombinant Fab antibody fragment in the format Fab-F-Spy2-H with specificity for green fluorescent protein (GFP). It has no known reactivity with mammalian proteins or other antigens. It has been tested by ELISA for specificity to GFP, but has not been tested in other applications. It is suggested as a negative control reagent when using other HuCAL antibodies of the same Fab format.

It is recommended that this reagent is used at the same concentration as the test reagent.
