Dear Histonetters,

Lately I am having difficulties with the storage of my antibodies.

I keep them at -20ºC in undiluted aliquots. After few months a kind of web
or lattice grows in the liquid. It is evident after unfreezening. The
antibody keeps working but I am afraid this is not any pleasant.

I would very greatful with your input.

By the way the provider states an expiring date of only six months. Is this
reasonable?

Best regards from Spain

Pablo Sanchez
