A Western blot analysis is performed on a panel of human tissues and cell lines to evaluate antibody specificity. For antibodies with uncertain result a revalidation using an over-expression lysate is performed.
Immunohistochemistry is used to validate the antibody staining and for assessing and validating the protein expression pattern in normal human tissues. For validation of antibody staining the immunohistochemical staining patterns obtained using tissue microarrays (TMA) containing 44 different normal tissue types (IHC tissue) , as well as, cell microarrays (CMA) containing 44 different widely used and well characterized human cell lines (IHC cells) , are compared to staining patterns from independent antibodies or to RNA expression patterns. For validation of protein expression patterns in normal human tissues the TMA staining patterns are evaluated together with RNA-seq data from internal and external sources and available protein/gene characterization data.
Nuclear positivity in subsets of neurons, most abundant in cerebral cortex.
A Western blot analysis is performed on a panel of human tissues and cell lines to evaluate antibody specificity. For antibodies with unreliable result a revalidation using an over-expression lysate is performed.
Western Blot is used for quality control of the polyclonal antibodies generated in the project. After purification, the antibodies are used to detect bands in a setup of lysate and different tissues. The result is then scored Supported, Approved, or Uncertain.
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.
