Definitions
- Indicator peptide for the diagnosis and / or prediction of cardiovascular and / or endothelial diseases.
- the invention relates to an indicator peptide for the diagnosis and / or prediction of cardiovascular and / or endothelial diseases, to an antibody composition for the determination of C-type natriuretic peptides and to an immunoassay method for pro CNP (1-80), an immunoassay for Determination of human pro CNP (l-80) and an in vitro diagnostic or progno sev experienced.
- Cardiovascular damage is a common clinical disease that contributes to or is responsible for various syndromes, especially in the elderly, such as for arteriosclerosis, kidney failure and the like.
- CNP C-type natriuretic peptide
- CNP C-type natriuretic peptide
- T. Sudoh and his collaborators Biochem-Biophys.Res. Commun., 168: 863-879, 1990.
- human CNP is produced in the human vascular system by endothelial cells (S. Suga et al, J.Clin Invest 1992: 90: 1145-9). It is believed that human C-type natriuretic peptide is produced as a precursor consisting of 126 amino acids.
- proCNP proCNP or CNP (1-103)
- ProCNP is cleaved before or during secretion to form the biologically active form of CNP, CNP-22.
- a prolonged form at the N-terminus, CNP 53, is the molecular form of CNP which occurs mainly in the porcine brain (Minamino et al, Biochem. Biophys. Res. Commun. 1990, 170: 973-9).
- CNP immunoreactivity was found in human vascular endothelial cells (Singo et al Am.
- proCNP (1-80) and proCNP (1-50), i.e. the peptides consisting of the first 80 and 50 amino acids, respectively, calculated from the N-terminus of proCNP, are in patients suffering from endothelial diseases (e.g. arteriosclerosis, Naruka T. et al, Circulation 1996; 94: 3103-8) and kidney failure (Igaki T. et al, Kidney Int. Suppo. 1996, 55: 144-7).
- the present invention is based on the consideration that the N-terminal fragments of human proCNP (1-103) (SEQ ID NO: 1), similar to proCNP (1-80) and proCNP (1-50), due to their versus CNP -Hormones (CNP-22 or CNP 53) long half-life as good diagnostic indicators or means of prognosis for all cases of endothelial damage or renal diseases, eg Risk for
- Arteriosclerosis septic shock or chronic kidney dysfunction can serve.
- ProCNP (1-80) SEQ ID NO: 1
- an immunogenic Fragment therefrom can advantageously be conjugated to an immunogenic protein or peptide as is known from the prior art.
- the invention is to provide an indicator polypeptide
- polypeptide according to the invention being the N-terminal fragment proCNP (1-80) (SEQ ID NO: 1) of the C-type natriuretic precursor amino acid
- polypeptides can be used to obtain polyclonal or monoclonal antibodies that are specific for CNP (1-80) (SEQ ID NO: 1).
- Another aspect of the present invention is a
- Immunoassays are of course known in the art, e.g. RIA, EIA, fluorescence immunoassay (FIA) or dry chemistry test strip immunoassays.
- a monoclonal or polyclonal antibody according to the invention in immobilized form, e.g. on a microtiter plate, on membranes or particles to isolate the target compound proCNP (l-SO).
- the bound antigen can be detected in a sandwich assay by means of an additional soluble antibody according to the invention, which can be a monoclonal or polyclonal antibody.
- This antibody can either carry a label or, even more simply, can be labeled even later by reacting with a second antibody that carries a label.
- the second antibody can be an anti-sheep antibody.
- Suitable labels include radionuclides, fluorescent substances, for example europium based hybrid processes, dyes or colored particles, such as colloidal gold.
- a binding assay can be used in which a known amount of labeled human proCNP (1-80) (SEQ.ID NO.l) or an antigenic fragment thereof is added to an analyte solution and brought into contact with a limited amount of immobilized antibody, whereby the amount of labeled antigen that is immobilized is inversely proportional to the amount of target antigen present in the analyte.
- the present invention further provides an immunoassay kit made from human proCNP (1-80) (SEQ ID NO: 1), an antigenic fragment thereof or a polypeptide extension thereof, which contains the following:
- Such an immunoassay and test kit can be used to examine related biological systems, as well as to diagnose or predict conditions in which the titer of human proCNP (1-80) (SEQ ID NO: 1) in body fluids is a diagnostic or is a preventive indicator.
- Another object of the present invention is also a method for
- human proCNP (1-80) (SEQ ID NO: 1) can also be used as a diagnostic tool for risk assessment for the development of arteriosclerosis (Naruka T. et al, circulation 1996, 94: 3103-8).
- the body fluid on which the immunoassay is carried out can be any body fluid in which human proCNP (1-80) (SEQ ID NO: 1) is present; however, plasma serum or urine will usually be used. In some cases it may be appropriate to extract the peptides or otherwise treat the sample before performing the assay.
- the human proCNP (1-80) (SEQ ID.NO.l) peptide or an antigen or immunogenic fragment thereof can be synthesized from the amino acids making them up using techniques well known in science, or formed by assembling pre-synthesized amino acid blocks. Recombinant expression of peptides is of course another very appropriate method of generating the antigen for immunization. Where marked material is necessary, the marking can be made using standard techniques.
- the human proCNP (1-80) (SEQ.ID NO: 1) or an antigenic fragment thereof can be conjugated to an immunogenic protein or peptides as is known in the art.
- the antibodies according to the invention can be produced by injecting proCNP antigen according to the invention into a host animal, etc. advantageously by a conjugate with an immunogenic protein as described above.
- Suitable host animals are, for example, a sheep, either to produce a serum which contains polyclonal antibodies, or, for example, a mouse or a rabbit, to obtain spleen cells for conversion to hybridomas or immortalized cell lines and thus to produce monoclonal antibodies.
- Example 1 Production of polyclonal or monoclonal antibodies against CNP (1-80)
- proCNP (1-80) SEQ ID NO: 1
- proCNP (1-19) proCNP (1-19)
- proCNP proCNP
- proCNP proCNP
- proCNP proCNP
- 51-79 proCNP
- the sheep received 2 mg of the corresponding 10 antigen mixed with non-ulcerative Freund's adjuvant (Guildhay, GB) and BCG (bacillus Calmette Guerlin)
- Microtiter plates were coated with synthetic proCNP peptide sequences (1 ⁇ g / ml). Sample blood was in phosphate buffer with 3% BSA 1:
- Monoclonal antibodies can be produced analogously, mice or rabbits being used as host animals and hybridomas being produced by processes known in the art.
- Example 2 Immunoassay for proCNP (1-80) (SEQ ID NO: 1) or immunoreactive fragments thereof.
- the antibodies can be used in various types of immunoassay for proCNP (1-80) (SEQ ID NO: 1) or immunoreactive fragments thereof. These include
- Enzyme-linked immunosorbent assay including 30 "sandwich” -type methods performed on microtiter plates or membranes.
