LCT and carcinoma: Apart from confirming the ability of N-terminal lactose to redirect antibody specificity towards core peptide regions consistent with our HA and NA studies, antisera raised to 2 short glycosylated peptide conjugates, Lac-Her2(270–281)-KLH and Lac-Her2(282–294)-KLH, were also capable of recognizing plate bound full length recombinant Her2 and importantly, native Her2 receptors on carcinoma cells.
