Figure Lengend Snippet: Proteome and peptide screens were used to evaluate potential off-target binding of affinity-purified p4796kb antibodies. a Manhattan plot displays results from the HuProt Human Proteome Microarray screen of antibody binding. Colors represent each block from the array, containing approximately 1000 proteins each. Spots represent individual protein intensity score from array. Hits are annotated with protein names. b Manhattan plot from peptide counter screen of 21 putative hits from proteome screen. Overlapping 15mer peptides were synthesized and printed on arrays. Spots represent individual peptide intensity scores from array. Peptide sequences of hits are displayed. Sera from guinea pigs immunized with p4796kb were tested for binding to putative hits from screens ( c ) and calcitonin family ( d ) measured by ELISA. Pre-immune sera were used as controls. Data are presented as means +/− SEM; n = 3. *** p < 0.0001.

Article Snippet: Guinea pig sera collected at week 15 post p4796kb immunization were assessed for their potential off target binding using HuProtTM Human Proteome Microarrays v4.0 (Cambridge Protein Arrays Ltd., Cambridge, UK) with over 20,000 individual proteins, representing more than 16,000 human genes, including the peptides of the calcitonin/CGRP peptide family.
