Re: [Histonet] Expired antibodies...for immunos..
And let us not forget that it's the antibody manufacturers who set these
expiration dates. Is there an actual science behind determining an
antibody's 'lifespan', or is it more of a business profit decision? It's
certainly cost-inefficient for a lab to pay upwards of $500 for an antibody
which you only use a few times before its expiration date hits, yet the
doctors/clients want these tests available.
If we can't change the wording on the rules and regulations in regards to
using antibodies past their expiration date, despite proof of their
continued reactivity... then we should encourage the manufacturers to set
more reasonable expiration dates.... or sell in smaller quantities, as Peggy
