Re: CD20

Try CD22 and/or CD79a.  We have seen a few patients whose B-cell lymphomas show equivocal CD20 immunoreactivity following Rituxan (?sp) anti-CD20 therapy.

Anyone have info on other B cell markers besides CD20? Our pathologists are
concerned that patients receiving Anti CD20 medication may not stain
correctly with the CD20 marker. Thanks in advance! j:>)
