Definitions

  • This invention relates to non-naturally occurring or synthetic peptides which mimic an antigenic site on the surface of feline immunodeficiency virus (FIV) envelope protein.
  • FV feline immunodeficiency virus
  • feline immunodeficiency virus A retrovirus termed feline immunodeficiency virus (FIV) is now known to be the etiological agent in feline acquired immunodeficiency syndrome (FAIDS). Testing for FIV is important in diagnosing exposure to the virus in order to to limit the spread of infection.
  • FAIDS feline acquired immunodeficiency syndrome
  • Detection of exposure to FIV is accomplished by measuring levels of FIV antibodies in serum, plasma, whole blood or saliva.
  • inactivated crude or purified viral protein from lysates of FIV-infected cells are used to coat a solid phase.
  • Biological samples suspected of containing FIV antibodies are incubated with the solid phase and after an
  • anti-feline antibody tagged with a detectable label is added to the solid phase.
  • the label which may be an enzyme, radioisotope or fluorescent molecule is measured to determine the presence of FIV antibodies in the sample.
  • the difficulty with using viral lysates as a source of FIV antigens is the high level of
  • This invention provides a highly sensitive and accurate detection or diagnostic procedure that does not require the use of virus or lysates thereof as a test reagent.
  • a polypeptide test reagent prepared by chemical means is used to detect the presence of antibodies to FIV in body fluids.
  • test reagent comprising a peptide having about twenty seven amino acids arranged in a specific sequence, preferably prepared by solid phase
  • the 27mer peptide is useful in a highly sensitive and accurate method for the detection of antibodies to FIV in serum.
  • a shorter 13mer peptide contained within the 27mer is similarly useful.
  • Peptides having specific immunoreactivity to FIV antibodies are selected from the group consisting of peptides containing from twelve to twenty seven amino acids, the sequence of which corresponds to a part or the entirety of the following sequence
  • the highly sensitive and accurate method for the detection of antibodies to FIV in serum comprises the following steps:
  • a solid phase such as polystyrene
  • a buffered solution containing from about 0.5 ug/ml to about 20 ug/ml of peptide, in an appropriate solvent such as phosphate buffered or borate buffered saline.
  • a detectable label which may be an enzyme, radioisotope or fluorescent molecule.
  • Horseradish peroxidase was activated by periodate oxidation (20 mM sodium metaperiodate) for two hours at 25°C. Peptide was added to the activate enzyme and allowed to react for two hours at 25 °C and the resulting conjugate was stabilized by sodium
  • conjugation ratio of peptide to enzyme of 15-35 The conjugated peptide is diluted for use into a solution containing 10 mM phosphate, 6% (w/v) bovine serum albumin and 0.1% (v/v) Tween 20.
