20090001025 | AGGREGATION AND DISPERSION METHODS OF MAGNETIC PARTICLES, SEPARATION AND DETECTION METHODS USING THE SAME AND DETECTION KIT - It is intended to provide a method capable of simply aggregating magnetic particles having a surface modified with a thermoresponsive polymer at a given temperature without heating or cooling an aqueous solution containing the magnetic particles, and a separation method and a detection method of a substance to be detected in a sample using the method. The method of separating a substance to be detected from a sample includes the steps of: mixing an adsorbent and the sample in an aqueous solution to adsorb the substance to be detected on the adsorbent, aggregating the adsorbent by changing a salt concentration in the aqueous solution; and collecting the adsorbent from the aqueous solution by a magnetic force, wherein said adsorbent comprises a magnetic particle of an average particle size of 50 to 1000 nm, a surface of which is modified with a thermoresponsive polymer and is immobilized with a substance having an affinity for the substance to be detected. | 01-01-2009 |
20090001321 | AQUEOUS SOLUTION OF POLYMER HAVING UPPER CRITICAL SOLUTION TEMPERATURE, AQUEOUS DISPERSION OF PARTICLE MODIFIED WITH THE POLYMER AND METHOD OF STORING THE SAME - It is intended to provide an aqueous solution of a thermoresponsive polymer and an aqueous dispersion of a thermoresponsive particle, which show an upper critical solution temperature (UCST) and are capable of maintaining a dissolved state and a dispersed state, respectively, even if they are stored for a long period of time at a temperature at which a ligand such as an antibody or an antigen is not inactivated. A UCST lowering agent is incorporated in a predetermined amount in an aqueous solution of a thermoresponsive polymer which shows a UCST in a state of containing water or an aqueous dispersion of a thermoresponsive particle containing the polymer, thereby lowering the UCST of the aqueous solution or aqueous dispersion to less than the storage temperature, and the resulting aqueous solution or aqueous dispersion is stored. | 01-01-2009 |

20110233453 | METHOD OF STORING THERMORESPONSIVE POLYMER IN STATE OF AQUEOUS SOLUTION - It is intended to provide an aqueous solution of a thermoresponsive polymer, which shows an upper critical solution temperature (UCST) and is capable of maintaining a dissolved state, even if it is stored for a long period of time at a temperature at which a ligand such as an antibody or an antigen is not inactivated. A UCST lowering agent is incorporated in a predetermined amount in an aqueous solution of a thermoresponsive polymer which shows a UCST in a state of containing water, thereby lowering the UCST of the aqueous solution to less than the storage temperature, and the resulting aqueous solution is stored. | 09-29-2011 |
20120070912 | DETECTION METHOD AND QUANTIFICATION METHOD FOR TARGET SUBSTANCE - Provided are a detection method and a quantification method for a detection target, which can detect and quantify the detection target rapidly, inexpensively, simply, and with high accuracy in a variety of environments. A method for detecting the detection target in a specimen includes processes in which there are mixed a first binding substance which binds a first material containing a stimuli-responsive polymer and a first affinity substance which has affinity for the detection target, a second binding substance which binds a hydrophilic second material and a second affinity substance which has affinity for the detection target, and a specimen; the resulting mixture is placed under conditions where the stimuli-responsive polymer agglutinates and the mixture is developed into a developing carrier, or the resulting mixture is developed into a developing carrier and the mixture is placed under conditions where the stimuli-responsive polymer agglutinates; the signal produced by the presence of the first binding substance or the second binding substance in the developing carrier is verified; and the presence of the detection target in the specimen is determined when the signal is different from that when the detection target is absent. The first affinity substance and the second affinity substance can bind to different positions of the detection target. | 03-22-2012 |
