Validation summaryi
All assays through which the antibody has been validated. Assays&annotation provide a detailed description of the different assays. The pie-charts indicate degree of validation.
Immunohistochemistry is used for validating antibody reliability by assessing staining pattern in 44 normal tissues. Validation scores include Enhanced, Supported, Approved and Uncertain.
Validationi
Results of validation by standard or enhanced validation based on assessment of antibody performance in 44 normal tissues.
Standard validation results in scores Supported, Approved or Uncertain. An image representative of the antibody staining pattern is shown.
Enhanced validation results in the score Enhanced and includes two methods: Orthogonal validation and Independent antibody validation. For orthogonal validation, representative images of high and low expression are shown. For independent antibody validation, four images of each independent antibody are displayed.
Antigen retrieval is a method used to restore/retrieve the epitope (antibody bidning region) of the target protein, cross-linked, and thus masked, during tissue preserving fixative treatment of the tissues.

Literature conformityi
Conformance of the expression pattern with available gene/protein characterization data in scientific literature and data from bioinformatic predictions.
UniProt is used as the main source of gene/protein characterization data and when relevant, available publications and other sources of information are researched in depth. Extensive or sufficient gene/protein data requires that there is evidence of existence on a protein level and that a substantial quantity of published experimental data is available from literature and public databases. Limited protein/gene characterization data does not require evidence of existence on a protein level and refers to genes for which only bioinformatic predictions and scarce published experimental data is available.
Consistent with extensive gene/protein characterization data.
RNA consistencyi
Consistency between immunohistochemistry data and consensus RNA levels is divided into five different categories: i) High consistency, ii) Medium consistency, iii) Low consistency, iv) Very low consistency, and v) Cannot be evaluated.
High consistency between antibody staining and RNA expression data.
PROTEIN ARRAY
Validationi
A protein array containing 384 different antigens including the antibody target is used to analyse antibody specificity. Depending on the array interaction profile the antibody is scored as Supported, Approved, or Uncertain.
Supported
Pass with single peak corresponding to interaction only with its own antigen.
Antibody specificity analysis with protein arrays. Predicted and matching interactions are shown in green.
The Structure section provides in-house generated structures, predicted using the Alphafold source code, for the majority of the proteins and their related isoforms.
Displaying protein features on the AlphaFold structures
Individual splice variants can be selected in the top part of the Protein Browser (see below) and different transcript-related features such as transmembrane regions, InterPro domains and antigen sequences for antibodies can be displayed in the structure by clicking on the respective features in the Protein Browser.
Clinical and population-based amino acid variants based on data from the Ensembl variation database and AlphaMissense (AM) predictions can be highlighted using the sliders to the right of the structure. These can also be used to colour the entire structure by residue index or make the structure autorotate.The structures are displayed using the NGL Viewer and can also be zoomed-in and rotated manually.
The Protein Browser
The ProteinBrowser displays the antigen location on the target protein(s) and the features of the target protein. Transcript names and schematic transcript structures including exons, introns and UTRs for the different isoforms are shown on top, and can be used to switch between the structures for the different splice variants.
At the top of the view, the position of the antigen (identified by the corresponding HPA identifier) is shown as a green bar. A yellow triangle on the bar indicates a <100% sequence identity to the protein target.
Below the antigens, the maximum percent sequence identity of the protein to all other proteins from other human genes is displayed, using a sliding window of 10 aa residues (HsID 10) or 50 aa residues (HsID 50). The region with the lowest possible identity is always selected for antigen design, with a maximum identity of 60% allowed for designing a single-target antigen (read more).
The curve in blue displays the predicted antigenicity i.e. the tendency for different regions of the protein to generate an immune response, with peak regions being predicted to be more antigenic.The curve shows average values based on a sliding window approach using an in-house propensity scale.

Signal peptides (turquoise) and membrane regions (orange) based on predictions using the
majority decision methods
MDM and MDSEC are also displayed.
Low complexity regions are shown in yellow and InterPro regions in green. Common (purple) and unique (grey) regions between different splice variants of the gene are also displayed (read more), and at the bottom of the protein view is the protein scale.
