摘要:
Immunoassays for measuring type II collagen (cartilage) resorption in vivo employ either one or two antibodies. A first antibody binds to DEKAGGA (SEQ ID NO:21) but not to GGFDEKAGGAQLG (SEQ ID NO:27), where the K symbols refer to lysine or preferably to cross-linking 3-hydroxypyridinium residues. Measurement of analyte binding to the first antibody in serum provides an indication of unmineralized cartilage resorption in vivo. A second antibody binds to GGFDEKAGGAQLG but not to DEKAGGA. Measurement of analyte binding to the second antibody in serum provides an indication of mineralized cartilage resorption in vivo. An indication of total (unmineralized and mineralized) cartilage resorption in vivo is provided by either measurement of analyte binding to the first antibody in urine, or by measurement of the total analyte binding to the first and second antibodies in serum.

摘要:
A system for detecting Barrett's metaplasia utilizes an illumination and imaging probe at the end of a catheter. The probe illuminates the wall of the esophagus and returns reflected light to be processed to provide a visual indication of the color of the esophageal wall. The position of the probe along the length of the esophagus is also measured to allow a medical practitioner to determine the location of the transition from the pink stomach lining to the white esophageal lining.
摘要:
Methods and compositions are provided for the production of a polypeptide which is immunologically cross-reactive with a naturally-occurring major outer membrane protein (MOMP) of Chlamydia trachomatis. A DNA construct including a replication system recognized by E. coli, and an MOMP gene under the transcriptional control of a .beta.-glactosidase promoter and terminator is provided. Recombinant phage .lambda.gtll/L2/33 was deposited at the American Type Culture Collection, 12301 Parklawn Drive, Rockville, Md. 20852, on Jan. 10, 1985 and granted accession no. 40157. L2 B9-F DNA was deposited at the American Type Culture Collection on Dec. 31, 1985, and granted accession No. 40217.

DNA expression vectors capable, in a transformant strain of yeast, of expressing a polypeptide under the control of a genetically distinct yeast promoter, processes of forming transformant strains of yeast and transformed yeast strains are disclosed.
摘要:
Methods for the detection, monitoring and treatment of malignancies are disclosed. Detection of the proliferation of T cells in response to in vitro exposure to a protein expression product of an activated oncogene or cancer-related gene associated with a malignancy, or detection of immunocomplexes formed between the protein expression product and antibodies in body fluid, allows the diagnosis of the presence of a malignancy. The present invention also discloses methods and compositions for treating a malignancy.
摘要:
Synthetic linear peptides embodied by Y-Tyr-Asp-Gly-X-Gly-Val-Gly (SEQ ID NO:1) which mimic the epitope recognized by mAb 1H11 (ATCC No. HB 10611) in cross-linked N-telopeptides of type I collagen (NTx).

摘要:
Compositions useful in quantitating collagen peptides to determine the rate of bone resorption are prepared by treating bone with a protease, such as collagenase, and purifying the compositions so as to enrich them with peptides capable of binding to the monoclonal antibody MAb-1H11.
摘要:
There is disclosed a device capable of continuously measuring the presence and concentration of an analyte or analytes and a method for using said device in a liquid and/or a gas phase reaction volume. The inventive device comprises a sensor probe, a reservoir, and a detector. The inventive device delivers reagent to the sensor probe in a flow method to directly and continuously renew reagent, thereby allowing the continuous measurement of the presence and the concentration of an analyte or analytes.
摘要:
Methods for detecting a unique strain of Chlamydia associated with acute respiratory disease are disclosed. These methods utilize monoclonal antibody directed against an antigenic determinant of the TWAR organism, or DNA probes capable of specifically hybridizing to at least a portion of the DNA sequence of the TWAR organism. A method for determining the presence of antibodies to the TWAR organism, utilizing elementary bodies of the TWAR organism as antigen is also disclosed.
