[Histonet] Expired antibodies...for immunos..

[Jan Shivers]

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 
stated below.
