Figure Lengend Snippet: Immunogenicity of EGFR peptide vaccine in outbred rabbits and antiproliferative effects in rabbit Abs and peptide mimics. (A–C) Relative levels of vaccine Abs measured in an ELISA assay showing immunogenicity of peptide constructs in rabbits (two per each construct). 2y + 3w, for example, indicates the titer of blood drawn 3 wk after the second immunization. (D) Binding of vaccine Abs to rhEGFR. y-axis represents absorbance, which shows levels of binding. MTT cell proliferation assay with breast and lung cancer cells using 50 μg/ml of vaccine Abs (E) and 50 μg/ml of peptide mimics (F) as inhibitors. The percentage inhibition was calculated using the formula (ODUNTREATED – ODTREATED)/ODUNTREATED × 100, and data shown represent an average of three different experiments, with error bars showing SD from the mean.
Article Snippet: ELISA was performed to evaluate the binding of the vaccine Abs to rhEGFR (R&D Systems) (as described in Ref. 20 ).
