Dear Judy,

You probably already know that ephrin B2 is expressed in arteries
and Eph-B4 in veins (Cell 1998 May 29;93(5):741-53).

I don't know if there are any antibodies available. But
you could use in situ hybridization :-)

Subject: markers for arteries or veins


> We are interested in differentiating between arteries and veins in the
adult rat pulmonary vasculature. Are there specific markers or antibodies we
could use? A variety of plant lectins exists which label endothelial cells
but the literature is confusing about their specificities. They may also
preferentially stain only certain organs.

> We are perfusing the rats, and cutting thick sections (~100 microns) on a
vibratome for confocal microscopy. So staining could be carried out either
at the time of perfusion or later, with the sections. A fluorescent marker
is required for the confocal technique.
