Abstract: An isolated protein sequence or peptide from the E2, E6 or E7 early coding region of human papillomavirus (HPV) that is soluble in an aqueous medium, and characterized by a relative paucity of tryptophan, methionine and cysteine residues, and a relative abundance of glycine and asparagine residues. Also disclosed are isolated protein sequences or peptides from the E2, E6 or E7 early coding regions of HPV 16 and 18 and methodologies for detecting or diagnosing cancer or cellular abnormalities. Detection or diagnosis of Cancer or cellular abnormalities may include detecting or diagnosing pre-cancerous or pre-malignant conditions, cervical dysplasia, cervical carcinoma, koilocytosis, hyperkeratosis, intraepithelial lesions, and other cancers.

Abstract: An isolated sequence or peptide isolated from an E2, E4, E6, E7 early or late coding region of human papillomavirus (HPV) that is soluble in aqueous medium, and characterized by a linkage to another protein sequence or peptide isolated from the E2, E4, E6, E7 early or late coding region of HPV by a spacer sequence, wherein the isolated protein sequence or peptide consists of more than 50% hydrophilic amino acids, and is recognized by a specific antibody of HPV. Also disclosed are isolated protein sequences or peptides from Harvey Ras (H-Ras), Kirsten Ras (K-Ras), and phosphatase and tensin homologue (PTEN) tumor suppressor proteins and Chlamydia trachomatis heat shock protein 60 (CHSP60 groEL1) and methods for detecting or diagnosing cancer or cellular abnormalities.

Abstract: The invention provides peptides designed to be highly reactive with antibodies from patients infected with oncogenic HPV. Also disclosed is a method for their use in an immunoassay to detect HPV infection and HPV associated epithelial cell abnormalities, most notably those associated with premalignant and malignant epithelial cell lesions. The peptides and the disclosed method are particularly useful for diagnosing carcinomas of the uterine cervix, or pre-stages thereof, or those at risk of development of carcinoma. The detection can be effected on blood samples, or other bodily fluid or tissue, by ascertaining the presence of IgA or IgG antibodies against HPV 16 and/or 18.
