How to generate antibodies against NGF using a vaccine?
5 answers
To generate antibodies against NGF using a vaccine, one approach involves synthesizing peptides based on hydrophilicity profiles of the NGF protein and using them for immunization. Peptides are conjugated to carrier proteins like keyhole limpet hemocyanin to induce an immune response. The resulting peptide antisera can be characterized through enzyme-linked immunoassays (ELISA) and immunohistochemistry to assess their reactivity and specificity. These peptide antibodies can then be purified and tested for their ability to bind to native NGF, with some antibodies recognizing NGF to a similar extent as polyclonal anti-NGF antibodies. This method allows for the production of antibodies targeting specific regions of NGF, which can be useful for immunohistochemical localization of NGF and its precursor.
