Hi Jorge Ivan,

If you want to perform some immunohistochemistry or tunnel assay, sections
must keep frozen, so you should make a shippment to Colombia with dry ice. 

If they defrost, proteins will degradate and it woudn´t be able to perform a
good antigen detection (IHC). No idea about ordinary stainings... depending
what you want to detect, I think better not defrost.
