Except here in the US, where we have federal laws that prohibit using
expired reagents. Enforced by laboratory accrediting agencies.

Hi Amy

I use VMS Benchmark XT and when the antibody has expired I "create" a new
lot number by putting (EXP1) at the end of it and adding one year to the
expiration date.  THen add the antibody dilution to the prepkit using the
"Refill" option rather than the "Partial" option.  As long as you're using
appropriate controls with your staining runs, there is no problem extending
the life of the antibody.

Hello all,

My supervisor wanted me to ask everyone who's posting about the expiration
dates of antibodies:  How can you use expired antibodies on a stainer such
as a Benchmark-which will not allow you to start the run due to expiration
dates on the containers?
