20090239306 | REFERENCE MATERIAL FOR ASSAYING D-DIMER - The present invention relates to a reference material for assaying D-dimer, comprising a fibrin degradation product, wherein no less than 70% of a total peak area has the molecular weight of no less than 500,000 in a molecular weight distribution of the fibrin degradation product, measured by gel filtration chromatography. | 09-24-2009 |
20090275140 | Hemoglobin Based Bilirubin Reference Material - What is described is a single reference material and method of making useful for calibrating or qualifying instruments that are diagnostic spectroscopically for bilirubin, hemoglobin, and hemoglobin fractions, and, optionally, diagnostic for other blood analytes by sensor means. | 11-05-2009 |
20100047913 | Colloidal Gold Single Reagent Quantitative Protein Assay - The invention provides methods for determining the concentration of polypeptides. The methods generally comprise labeling a polypeptide with a metal label such as colloidal gold and quantifiably detecting the polypeptide-metal complex; the methods are improvements over other quantification assays that use colloidal gold. The invention further provides kits for practicing the methods. | 02-25-2010 |
20100233815 | Methods for the Development of a Biomolecule Assay - The present teachings provide methods for the development of a mass spectrometric based assay for a protein in a sample using parent-daughter ion transition monitoring (PDITM). In various aspects, the present teachings provide methods for developing a mass spectrometric based assay for a protein in a sample without the use of a standard for the protein. In various embodiments, the sample comprises proteolytic fragments of a protein which is present in low abundance in the physiological fluid from which it is derived. | 09-16-2010 |
20110014710 | COMPOSITIONS, METHODS AND KITS FOR BIARSENICAL FLUOROPHORE LABELING - Methods, compositions, and kits for labeling tetracysteine-tagged proteins with biarsenical fluorophores with increased specificity, including compositions, methods and kits particularly adapted for labeling of tetracysteine-tagged proteins to be resolved within an electrophoresis gel. | 01-20-2011 |
20120003743 | STABILIZING AGENT FOR CONTROL MATERIAL, CONTROL MATERIAL CONTAINING THE STABILIZING AGENT, AND MEASUREMENT KIT COMPRISING THE CONTROL MATERIAL - An object of the present invention is to provide a control material which can be preferably employed in detection of 1,5-anhydro-D-glucitol and glycoalbumin, which are employed as excellent indices for diabetes. The present inventor has found that mannitol which is added to serum or plasma used as control material stabilizes 1,5-anhydro-D-glucitol and glycoalbumin present in the serum or plasma for a long period of time, and that the object can be attained through provision of (1) an agent for stabilizing control material, the agent being composed of mannitol and (2) control material containing mannitol and 1,5-anhydro-D-glucitol. | 01-05-2012 |
20130217133 | AUTO-DEVELOPING AND REGULARLY-WEIGHTED PROTEIN MOLECULAR WEIGHT MARKER KIT AND METHOD FOR PREPARING THE SAME - The present invention provides an auto-developing and regularly-weighted protein molecular weight marker kit, comprising: (a) a plurality of recombinant proteins having formula (I), | 08-22-2013 |
20140024120 | AUTOMATED PROTEIN ANALYZER - A dye binding method for protein analysis is disclosed. The method includes the steps of preparing an initial reference dye solution of unknown concentration from an initial reference dye concentrate and creating an electronic signal based upon the absorbance of the initial reference dye solution. Thereafter, an electronic signal is created based upon the absorbance of a dye filtrate solution prepared from the initial reference dye solution and an initial protein sample. The absorbance signals from the reference dye solution and the dye filtrate solution are sent to a processor that compares the respective absorbances and calculates the protein content of the protein sample based upon the difference between the absorbances. An electronic signal is created based upon the absorbance of a successive dye filtrate solution prepared from the reference dye solution and a successive protein sample, and the absorbance signal from the successive sample dye filtrate solution is sent to the processor to calculate the protein content of the successive sample based upon the difference between the absorbance of the initial reference dye solution and the absorbance of the successive dye filtrate solution. | 01-23-2014 |
