virus receptor research--Help

[I-shiou Ng]

Hi there,
	I would like to ask to two questions about receptor research
1. How to make veiscles for ligand-binding assay?  Is there any good reference
for it?

2. Is there anyone label virus as ligand? What kind of reagent are you using--
lactoperoxidase or Iodobeads?  Is there any good reference?

Thanks
