Abstract:
The apparatus and method of the present invention disclose a system in which multiple injections may be made into a capillary array. The injections are spaced in time with each injection followed by an interval of electrophoresis. Once all samples are loaded into the capillaries, continuous electrophoresis and detection is used to separate and detect target compounds within the sample. The interval between injections is matched to the target compound migration rate to be sufficient to allow the target compounds to be detectably separated when the compounds reach the detector.

Abstract:
The present invention provides novel nucleic acid detection methods based on nucleic acid template-directed primer extension assays. Also provided are kits and genetic analysis methods. Included are microsequencing methods comprising detecting an incorporated nucleotide by measuring direct fluorescence intensity, fluorescence-based nucleic acid detection methods using oligonucleotide primers hybridizing to both complementary strands of a nucleic acid sample, and methods for decreasing background signal in nucleic acid template-directed primer extension assays.

Abstract:
The invention relates to a capillary blood sampling device, incorporating a filter and, downstream of the same, an absorbent material for separating a blood plasma phase from a cellular phase, characterised in that the filter comprises successively: a pre-filter (6) for distributing the blood on the surface of a first membrane (2) with pores of size 0.1 µm to 5 µm, said membrane being provided with an agglomeration agent and said first membrane (2).
Abstract:
Devices and methods for carrying out a chemical or biochemical protocol are disclosed. In one embodiment, the chemical or biochemical protocol is performed by cycling at least one thermal transfer member between at least two temperatures while liquid samples on which the chemical or biochemical protocol is to be performed are continuously moving through at least one temperature regulated zone upon which the at least one thermal transfer member acts. In some embodiments, the device comprises a sample transport member that comprises liquid samples in sample receiving regions. The sample transport member moves the samples continuously through a temperature regulated zone which cycles between at least two temperatures while the liquid samples are moving through a temperature regulated zone on which at least one thermal transfer member acts. In some embodiments, the sample receiving regions comprise wells, hydrophillic films or hydrophillic filaments.

Abstract:
A solid-phase nucleic acid amplification method using a primer immobilised on a functionalised heat-resistant solid support, wherein said primer is immobilised on the solid support via a linking arm consisting of a polyfunctional molecule which forms a covalent bond between the solid support and a first functional group of said polyfunctional molecule, and between the 5' end of said primer and a second functional group of said polyfunctional molecule.
