RE: [Histonet] Expiration date

From:"Sebree Linda A."


CAP regulations do not allow for the use of expired antibodies and
reagents so we try to purchase in volumes that will be used up by their
expiry date.  Also, our inhouse QA/QC personnel tend to go by the book
as well so we don't have much choice in the matter.

What should we do with antibodies and reagents after their indicated 
expiration dates? Theorectically they shouldn't be estable after the 
expiration date but we do know that most of them still works
should we just throw them out and not use them anymore, wouldn't this be
way for the manufacturers manipulate their sellings? Need some
