IL4 assay

You may want to try fMLP (available from Peninsula Labs).  The only problem with
this protein is that it activates the neutrophils, so you will get a lot of
other stuff produced as well.  The optimal concentration for fMLP is ~0.1um (at
least for neutrophils), but I'm not sure what time frame would be best for
stimulating IL-4 production.

Hope this helps
