[Histonet] pan B-cell marker for frozen mouse tissue

[Michele Wich]

I am trying to find the most appropriate pan B-cell marker for IHC on
frozen mouse tissue. I know that CD45R/B220 used to be the most commonly
used, but recent publications suggest PAX5 or CD19 as more restricted to
the B-cell lineage. Does anyone have any other suggestions, or are these
generally what people are using these days?

Thanks for any info.
