         19 . A method of determining whether a test compound affects binding of HSV gD with HveA, the method comprising (a) making a first preparation comprising a surface having at least a portion of HveA bound thereon, the test compound, and a suspension of a phage in contact with the surface, wherein the phage displays a cyclic peptide selected from the group consisting of BP-1 and BP-2, and mutants, homologs, derivatives, and variants of BP-1 and BP-2; 
 (b) assessing the amount of phage bound with the surface in the first preparation; and    (c) comparing the amount of phage bound with the surface in the first preparation and the amount of phage bound with the surface in an otherwise identical preparation to which the test compound is not added, whereby a difference between the amount of phage bound with the surface in the first preparation and in the otherwise identical preparation is an indication that the test compound affects the binding of gD with HveA.    
     
     
         20 . A method of determining whether a test compound affects HSV gD binding with HveA, the method comprising 
 (a) making a first preparation comprising a surface having at least a portion of HveA bound thereon, the test compound, and a cyclic peptide selected from the group consisting of BP-1 and BP-2, and mutants, homologs, derivatives, and variants of BP-1 and BP-2, in contact with the surface;    (b) assessing the amount of the peptide bound with the surface in the first preparation; and    (c) comparing the amount of the peptide bound with the surface in the first preparation and the amount of peptide bound with the surface in an otherwise identical preparation to which the test compound is not added,    whereby a difference between the amount of the peptide bound with the surface in the first preparation and in the otherwise identical preparation is an indication that the test compound affects HSV gD binding with HveA.
