  • Achievements include research in protein structure-function relationships in bovine pancreatic ribonuclease A, human complement protein C3, ricin, blocked ricin, and monoclonal antibodies. Development of affinity chromatography media for separation of biologicals. Development of novel cross-linkers for the preparation of antibody heteroconjugates, protocols for removal of toxic contaminants and minimizing aggregation in the proprietary toxin (blocked ricin) and immunotoxins.

    Development of influence of chemical deglycosylation on the biological properties of blocked ricin. Development of first demonstration that a single amino acid substitution affects the kinetics of protein folding in ribonuclease A. Development of evidence for third galactose binding site in ricin B-chain, chemistry and biology of food allergens.

    Mannitol in pomegranate and mushroom. Development of 21 kD allergen (thaumatin-like protein) in sapodilla. Development of horsegram lectin (Dol b Agglutinin).

    Development of 60-71 kD allergens (polyphenol oxidase) in eggplant. Development of almond profilin (Pru du 4). Development of generation of antibodies to haptens (mannitol, erythritol, and xylitol) for development immunoassays for specific sugar alcohols.

    Development of role of lectins (potato, banana, garlic and horsegram) in non-allergic food hypersensitivity. Development of non-specific activation of basophils/mast cells by dietary lectins. Immunomodulators from plant sources (garlic, onion, guduchi).
