Affinity Measurement Description:

ELISA measurements of the binding to sera from EHV-1 infected gnotobiotic foals expressed as A490. The samples were taken in duplicate and the results are expressed as an average value. NT deneotes not tested.

Brief Description:

Briefly phage (3e9-9e10 plaque forming units, pfu) in 100 ml PBSTG (phosphate buffered saline containing 0.05% Tween 20 and 0.5% goat sera, Seralabs) were incubated with or without biotinylated equine IgG for 5h at 37°C. An equal volume of M-280 streptavidin-coated magnetic beads (Dynal), washed three times with PBSTG, was added, mixed and stored at room temperature for 5 min.

BiopanningDataSet Comments:

The sequences of the amino acids displayed were aligned with protein sequences of EHV-1, thereby identifying a number of potential antibody binding regions. Presumptive epitopes were identified within the proteins encoded by genes 7 (DNA helicase:primase complex protein), 11 (tegument protein), 16 (glycoprotein C), 41 (integral membrane protein), 70 (glycoprotein G), 71 (envelope glycoprotein gp300), and 74 (glycoprotein E). Two groups of sequences, which aligned with either glycoprotein C (gC) or glycoprotein E (gE), identified type-specific epitopes which could be used to distinguish between sera from horses infected with either EHV-1 or EHV-4 in an ELISA using either the phage displaying the peptide or synthetic peptides as antigen. The gC epitope had been previously identified as an immunogenic region by conventional monoclonal antibody screening whereas the gE antibody binding region had not been previously identified.
