Fluorescence Quenching by Complex of a DNA Aptamer and Porphyrin for Sensitive Detection of Porphyrins by Capillary Electrophoresis

extremal region detection guided by maxima of gradient magnitude

a problem of computer vision applications is to detect regions of interest under dif- ferent imaging conditions. the state-of-the-art maximally stable extremal regions (mser) detects affine covariant regions by applying all possible thresholds on the input image, and through three main steps including: 1) making a component tree of extremal regions’ evolution (enumeration), 2) obtaining region ...

selection of high affinity dna-aptamer for activated protein c using capillary electrophoresis

Multiwavelength fluorescence detection for DNA sequencing using capillary electrophoresis.

Multiwavelength detection of laser induced fluorescence for dideoxynucleotide DNA sequencing with four different fluorophores and separation by capillary gel electrophoresis is described. A cryogenically cooled, low readout noise, 2-dimensional charge-coupled device is used as a detector for the on-line, on-column recording of emission spectra. The detection system has no moving parts and provi...
