[Histonet] Using lectin BS-1 for staining endothelial cells

[Gabriel Anesetti]

Hello Histonetteers,
I am having problems with the staining of rat endothelial cells in 
paraffin sections using a biotin labeled lectin from Bandeiraea 
Simplicifolia BS-1 (from Sigma). The lectin does not appear to be 
staining any of the endothelial cells. I have tried using citrate buffer 
for antigen retrieval and DAB, DAB + NiCl or FICT to visualize the site 
of reaction. Sections are from ovary grafts and have very new blood 
vessels forming. Any information would be helpful.
 
Thanks
