CD73 Antibodies

["Zulu / Fales Bernadette ", SCI]

Hi
Does anyone know where i could find CD73 antibodies. CD73 has been 
characterised as an ectoenzyme 5`nucleotidase. I'm currently doing a 
biochemical assay using lymphocytes but I'm also interested in doing 
immunohistochemistry of the enzyme on lymhocytes.
If anyone knows anything about this enzyme that would assist me, both for 
the biochemical and immunohistochemistry, please let me know. 

Thankyou
