Freezed antibodies - (Nov/14/2007 )

Hello everybody,
I have frozen antibodies from SantaCruz. On the antibody label is stated “Do not freeze” but somebody freezed them. Are the antibodys still usable or not? I know that SantaCruz uses gelatin, but the antibodies have been freezed only once or twice. So what is your opinion?

We freeze all antibodies at -80, even if they say not to freeze. We havnt had problems.
