Stabilty of antibodies

I agree that most antibodies are stable at 4 c for along time, but
only if kept "clean". Microbial contamination is the most common cause
for problems. Even if you include a preservative, unless the material
starts with a low bioburden (microbes) the antibody will be
inactivated quickly. Also remember that plastic vials not claimed as
sterile can be the main problem.
