  • Patent number: 10802022
    Abstract: Two Borrelia burgdorferi recombinant proteins were expressed in E. coli. These two proteins were generated from (a) the full length dbpA gene combined with the invariable region 6 of the VlsE gene (dbpA/C6), and (b) the full length OspC gene combined with the coding sequence for amino acids 1-121 of the E. coli maltose binding protein gene (OspC/MBP). Methods of using these recombinant proteins for detecting anti-Borrelia burgdorferi antibodies in patient sera and diagnosis of Lyme Disease are described.

  • Patent number: 10613101
    Abstract: A new method of in vitro monitoring and assessing the need of a medication which interferes with the regulation of the parathyroid hormone level in a kidney patient subject to oxidative stress, notably hemodialysis patients. FIG. 1 shows the distribution of n-oxPTH concentrations in 340 hemodialysis patients (224 men and 116 women) with a median age of 66 years (IQR, 56 to 75 years), a median time since initiation of dialysis (dialysis vintage) of 266 days (IQR, 31 to 1209 days), and a median dialysis dose (kt/V) of 1.2 (IQR, 1.1 to 1.3). The cause of chronic kidney disease was nephrosclerosis in 113 cases (33%), diabetic nephropathy in 107 cases (31%), chronic glomerular nephritis in 29 cases (9%), polycystic kidney disease in 9 cases (3%) and other/unknown in 82 cases (24%). The median n-oxPTH concentration was 5.9 ng/L (IQR, 2.4 to 14.0 ng/L). n-oxPTH concentrations were not different in men and women (5.9 ng/L; IQR, 2.4 to 14.2 ng/L; n=224; vs. 5.5 ng/L; IQR, 2.4 to 14.0 ng/L; n=116; p=0.915).

  • Patent number: 9005910
    Abstract: The purpose is to produce, with high reproducibility, a complex of labeled probes and a carrier, said complex being to be used for detecting and measuring a target substance to be measured with high sensitivity and high stability. The means for accomplishing the purpose is that a label is bound to a probe-water soluble carrier conjugate using specific binding of an avidin compound such as avidin, streptavidin, etc. to biotin, and the binding of the avidin compound to the probe is performed before the binding to the carrier. Namely, after conjugating the avidin compound to a substance which is capable of binding to the target substance, the conjugate is bound to a high-molecule water-soluble carrier to produce a complex of the avidinized probes and the water-soluble carrier. Then the complex of the avidinized probes and the water-soluble carrier is mixed with a biotinylated label.

The method involves measuring the activity states for signaling proteins in a diseased cell and determining whether the activity states are different from the activity states observed for a reference cell such as a normal cell. Based on the observed differences, combinations of two or more drugs are selected to reduce these differences. Treatment of a subject with the combinations restores the activity states of the signaling proteins of the deranged disease-associated signaling pathways toward the activity states observed in the reference cell. Since the diseased cell and the reference cell can both be obtained from the same subject, combinations of drugs that specifically target patient-specific signaling derangements is possible.

  • Patent number: 8835125
    Abstract: Disclosed are compositions and methods for the labeling of two or more targets with different labels. Specifically, disclosed are compositions for biotin and the protection of biotin within multilabel assays which employ the biotin-biotin binding protein binding relationship for each distinct label in relation to targets such as nucleic acids, polypeptides, antibodies or cells. These multilabel assays are enabled through the use of biotin with desthiobiotin, orthogonal protecting schemes for biotin, or a combination of the approaches.

  • Publication number: 20140242575
    Abstract: The invention provides inexpensive kits and methods for determination of an analyte in a sample with very high sensitivity. Analyte can be determined using an analyte binding member such as an antibody or an oligonucleotide, which can be directly or indirectly linked to an enzyme. The kit and method uses a compound that is altered in the presence of the enzyme, and that precipitates into crystalline particulates. The reaction composition with crystalline particulates is placed between two polarizers which are in an orthogonal arrangement, and the presence of particulates is observed, correlating to the analyte in the sample.

  • Patent number: 8815528
    Abstract: The present invention is based on the discovery that MHC heavy chain monomers immobilized to a solid surface are still capable of forming detectable conformational epitopes and being detected by conformation-dependent antibodies. Methods for detecting peptide binding to HLA monomers, and methods for measuring the relative degree of binding between two MHC-binding peptides as well as a method of measurement for the rate of dissociation of peptides from MHC complexes are provided. The present invention also provides systems and kits useful for conducting the methods of the present invention.

  • Publication number: 20140186831
    Abstract: Solid supports for chemiluminescent assays are provided. The solid support includes a plurality of probes covalently or physically attached to the support surface and a chemiluminescent enhancing moiety incorporated onto the surface or into the bulk of the support. The solid support can be a multi-layered support including an upper probe binding layer (e.g., an azlactone polymer layer or porous functional polyamide layer) adjacent to a cationic microgel layer. The azlactone-functional polymer can be a copolymer of dimethylacrylamide and vinylazlactone crosslinked with ethylenediamine. The cationic microgel layer can be a cross-linked quaternary onium salt containing polymer. A method and a kit for conducting chemiluminescent assays using the solid supports is also provided. The kit comprises a dioxetane substrate, a biopolymer probe-enzyme complex, and a solid support.

  • Patent number: 8765488
    Abstract: Sensing compositions, sensing element, sensing systems and sensing devices for the detection and/or quantitation of one or more analytes, Compositions comprising carbon nanotubes in which the carbon nanotubes retain their ability to luminesce and in which that luminescence is rendered selectively sensitive to the presence of an analyte. Compositions comprising individually dispersed carbon nanotubes, which are electronically isolated from other carbon nanotubes, yet which are associated with chemical selective species, such as polymers, particularly biological polymers, for example proteins, which can interact selectively with, or more specifically selectivity bind to, an analyte of interest. Chemically selective species bind, preferably non-covalently, to the carbon nanotube and function to provide for analyte selectivity. Chemically selective species include polymers to which one or more chemically selective groups are covalently attached.

    Abstract: The invention relates to the use of novel biomarkers and biomarker combinations having utility in the early determination of an individual's critical and/or life threatening response to illness and/or in predicting outcome of said illness. The measurement of expression levels of the products of the biomarkers and combinations of biomarkers of the invention have utility in making the determination of an individual's critical and/or life threatening response to illness. In some embodiments, the biomarker and biomarker combinations are agnostic and are independent of the pre-identification and/or determination of the cause or nature of the illness. In some embodiments, the biomarkers and biomarker combinations can be utilized to select treatment and/or monitor the effectiveness of treatment interventions for an individual who has a critical illness.
