Its depend on the type of Abs and its stability, antibodies 1 hour are fine at room temperature (for several plant viral AB it works after 3 days with no harm , Usually I stored at 4°C and these work perfectly fine for months), although it depends on the Abs and how it was produced and manufactured; but, generally, 1 hour is not a big time to lose their binding activities. Antibody is like any protein, some can't be frozen, most need to be stored at 2 to 8ᵒC and can last for several months. Antibodies are meant to be stored at -20C , each freeze-thaw cycle lead to reagent be less efficient. Ideally, -20C antibodies have glycerol-like components pre-added and you do not really need to keep them out for too long to thaw. good luck
