Reposting discontinuation of 2nd Ab supply

We have discontinued the service to provide secundary fluorescently labelled antibodies.

So, please be aware that you are taking our personal stocks when you remove aliquots from our freezer. Contact us when you need a specific secondary antibody, we can supply an aliquot or help you find someone who has a suitable dye conjugate.

Why?

This service is too expensive to keep in place. It was useful to maintain a relatively fresh stock that is continuously probed for functionality, this way users did not need to worry about out-of-date fluorescent antibodies.

How to story your own set of fluorescent Antibodies

Keep stocks as 50% glycerol solutions in -20 C freezers,  then long term storage is very stable. The problem of drying and getting aggregates of non-functional antibodies is minimised by this procedure. Our advice is to generate a stock of secondary antibodies and share this among department members (one or two persons responsible for the ordering, aliquotting and distribution clarifies cost streams and inventory overview). A handy tool to keep track of inventories is supplied as freeware by Quartzy or the newly implemented eLabInventory software whitin the UU community for administration of GMOs.
