  • Assay for Epstein-Barr virus infection with solid phase bound synthetic polypeptides
    Patent number: 5116725
    Abstract: Antigens, immunogens, inocula, antibodies, and particularly diagnostic methods and systems relating to Epstein-Barr virus nuclear antigen (EBNA) are disclosed. The diagnostic methods and systems utilize a synthetic, random copolymer polypeptide containing about 8 to about 40 amino acid residues that includes the overlapping five and six amino acid residue sequences(i) --Gly--R.sup.1 --Gly--R.sup.2 --Gly--wherein R.sup.1 and R.sup.2 are amino acid residues selected from Ala, Asn, Arg, Gly, Leu, Pro, Ser, and Thr with the provision that R.sup.1 and R.sup.2 are not both Gly; and(ii) --Gly--Ala--Gly--Gly--Ala--Gly--.The polypeptide contains at least 50 mole percent Gly residues. The diagnostic method and system are particularly useful for assaying for the stage of mononucleois disease, and the presence of nasopharynegeal carcinoma.

  • Hybridoma cell lines and monoclonal antibodies to theophylline
    Patent number: 4524025
    Abstract: Monoclonal antibodies to theophylline having 5% or less cross-reactivity with caffeine and the continuous hybrid monoclonal cell lines for their production are provided. These antibodies are useful in a particle-enhanced turbidimetric inhibition immunoassay for theophylline.
