摘要:
A system of quantitatively determining a biomolecule, which has: allowing fluorescent silica particles capable of emitting fluorescence detectable by a flow cytometer to capture a target biomolecule fluorescent-labelled for quantitative determination; detecting the fluorescence emitted from the fluorescent silica particles themselves by using the flow cytometer; and measuring the intensity of the fluorescence of the labelled target biomolecule, thereby quantitatively determining the target biomolecule.
摘要:
Colloidal silica particles containing a fluorescent dye compound, composed of a silica particle containing a silica component and a fluorescent dye compound chemically bound or adsorbed thereto,wherein the colloidal silica particles containing a fluorescent dye compound have an average diameter of 30 nm or less, and wherein said silica particles are used simultaneously as fluorescent-labelling nanobeads; a fluorescent nano-material comprising said colloidal silica particles; and a biochip and an assay method using the same.

摘要:
Disclosed are a pH or concentration measuring device and a pH or concentration measuring method which enable measurement in the shortest possible time even in an object to be measured having low buffer capacity. Specifically disclosed are a pH or concentration measuring device and measuring method for measuring the pH or concentration of a sample solution that is an object to be measured, the device being provided with first and second sensors that each output a signal corresponding to the pH or concentration of a solution, an inspection tube that is provided with a first room in which the first sensor is disposed and a second room in which the second sensor is disposed, a feeding means that feeds a baseline solution into the inspection tube, and an injecting means which injects the sample solution into the first room of the inspection tube and brings the sample solution into contact with the first sensor, wherein a vibration means which vibrates the interface between the sample solution stored in the first room and the baseline solution is provided.
摘要:
A method for measuring trace amounts of analyte substance(s), which utilize a pH electrode is disclosed. This method is by far simpler than conventional optical detecting systems. The apparatus for practicing the method is also disclosed. By the use of pH electrode, the apparatus is compact, inexpensive and easy to operate, and hence usable in small-size and medium-size hospitals or clinical laboratories and by patient's bedside.
摘要:
An apparatus for measuring the quantities of chemical substances contained in a solution to be assayed by using a chemical-substance sensitive sensor consists of a potentiometric electrode which responds selectively to chemical substances, and a liquid-junction type reference electrode including a tube, a porous thread member housed in the front end opening of the tube and having a pore capacity of 0.2 cc/g or more and at least the surface of which is hydrophilic, a silver-silver chloride wire is provided and housed in the tube so that at one end of the wire is in contact with the thread member and the wire which extends along the tube. The wire is connected to a connector at the other end opening of the tube, an electrical insulating resin fills said tube, at least at the front end portion thereof, for fixing both the silver-silver chloride wire and the thread member by contact therewith and for stopping said tube. An internal solution is retained by suction in said porous thread member. This apparatus is advantageously used for monitoring the living body and may be thermally sterilized.

According to the present invention, there are provided nanofunctional silica particles including a coating layer containing one or more silica compounds selected from the group consisting of mercaptopropyl trimethoxysilane (MPS), mercaptopropyl triethoxysilane (MPES), mercaptopropyl methyldimethoxysilane (MPDMS), trimethoxy[2-(7-oxabicyclo[4.1.0]-hept-3-yl)ethyl]silane (EpoPS), thiocyanatopropyl triethoxysilane (TCPS), acryloxypropyl trimethoxysilane (ACPS), and aminopropyl trimethoxysilane (APS); and functional particles in the coating layer, and being used in imaging, assay, diagnosis, treatment or the like, medicine or bioresearch.
摘要:
A network facsimile system has a communication terminal and relaying server. The network facsimile system is configured such that the communication terminal can transmit an image, through the relaying server, to a destination terminal outside the network facsimile system, that the communication terminal transmits an image to the relaying server in accordance with a predetermined communication protocol. The relaying server transmits an image to the destination terminal in accordance with a facsimile communication protocol. The communication terminal includes a notification system that notifies a user of the communication terminal of an operation status information indicating an operation status of the network facsimile system during a relaying server side operation period.
