  • Immunoactive peptides and antibodies and their use in anti-allergy treatment
    Patent number: 5955076
    Abstract: An immunogen comprising a residue of a histamine-releasing peptide comprising a cationic N-terminal head and a hydrophobic C-terminal tail, together with a residue capable of eliciting antibodies against said peptide whilst inhibiting histamine release by said peptide is useful in anti-allergy treatment. Preferably the histamine-releasing peptide is of formula:Lys-Thr-Lys-Gly-Ser-Gly-Phe-Phe-Val-Phe,optionally amidated at the C terminal.Antibodies to the histamine-releasing peptide are useful for passive immunisation.
    Type: Grant
    Filed: June 7, 1995
    Date of Patent: September 21, 1999
    Assignee: Peptide Therapeutics Limited
    Inventors: Denis Raymond Stanworth, Ian Victor Lewin, Sarita Nayyar, Valerie Jones
  • Immunodiagnostic assay for rheumatoid arthritis
    Patent number: 5827668
    Abstract: The assay of rheumatoid arthritis by reference to IgA-.alpha..sub.1 antitrypsin complex present in analytes is facilitated by certain novel antibody reagents. These are ligands comprising an antibody domain specific for an antigenic determinant of a complex of human IgA and .alpha..sub.1 -antitrypsin, this antibody domain being substantially non reactive with free human IgA and free human .alpha..sub.1 -antitrypsin. Monoclonal antibodies to the naturally occurring IgA-.alpha..sub.1 AT complex and monoclonal or polyclonal antibodies to a synthetic peptide are preferred.
