Triple A Polyclonals on the Human Protein Atlas
The Triple A Polyclonals have been used to map the human proteome by the Human Protein Atlas project. Each antibody has been used for IHC-staining of samples from 708 individuals originating from normal and cancer afflicted human tissues. Trained pathologists have evaluated the reliability of all IHC-staining patterns. In addition, ICC-IF-based confocal microscopy has been used to study subcellular distribution patterns in selected cell lines. Further, Triple A Polyclonals are characterized by Western Blot (WB), primarily in endogenous protein lysates from human tissues.
Specificity
Triple A Polyclonals are carefully designed using a proprietary antigen design software that selects a Protein Epitope Signature Tag (PrEST) sequence of between 50 to 150 amino acids having the lowest possible identity to other human proteins.
The PrEST concept secures the highest level of specificity when used for polyclonal antibody production. While full-length recombinant proteins often increase the risk for off-target binding, the PrEST antigen effectively reduces unwanted specificity by avoiding regions with high regional or local sequence identity to other proteins.
Reproduciblity
Developed by top Swedish scientists to create the Human Protein Atlas, our carefully designed Triple A Polyclonals are produced using the same standardized production process to ensure consistency. Furthermore, our unique antibody purification process, using the recombinant PrEST-antigen as the affinity ligand, achieves the highest reproducibility level. New production lots are tested in parallel with existing lots to ensure functionality and assay reproducibility in a real lab situation.
Versatility
Triple A Polyclonals combine optimal specificity with superior versatility across applications, including IHC, ICC-IF, and WB. While anti-peptide antibodies often generate too narrowly specific antibodies, the use of our PrEST-antigens results in advanced polyclonals that combine optimal specificity and minimal off-target binding with superior epitope recognition across applications, protein states and species.
