An urgent need to develop accurate biometric recognition system is expressed by governmental agencies at the local, state, and federal levels, as well as by private commercial companies. Fingerprinting is the most practical and widely used biometric technique. The pattern of ridges and valleys of each fingerprint is unique. The minutiae based algorithm is(More)
We report the production and characterisation of three monoclonal antibodies to the prion protein (PrP) of Rainbow trout (Oncorhynchus mykiss), a piscine protein with characteristic structural features common to mammalian prion protein. All of the antibodies were used to detect PrP in ELISA, Western blot and by immunohistochemistry. The antibodies showed(More)
Fingerprints are the most common biometric measure taken, and in recent years electronic fingerprint scanning has become commonplace. Although contactless fingerprinting methods are used, it is more common that the fingerprint is taken by pressing the finger against a computer scanner. In the current study, the advantages of the contactless technique are(More)
We present the design of a novel, mobile, and contact-less, fingerprint line scanner and blood vessel mapper. This system provides a means for acquiring fingerprints with less than 1% distortion in extremely high resolutions, presenting an ideal technology for high-security and individual identification applications. We envision a difficult scenario where(More)
Sample-related background signals in immunoassays can be measured by a variation of the double antibody sandwich principle, in which the unlabelled specific antibody is substituted by a similar unrelated non-specific antibody. This permits differentiation between the analyte-specific and the background signal components for each sample. The method permits(More)
The cytoplasmic pH value o f guard cells o f Valerianella locusta was determined from the distribution o f the weak acid [l4C]ABA between the medium and the cell, which was shown to be 8.1 ±0.1. Treatment o f guard cells in media with low pH (pH 5.0) and different concentra­ tions o f sodium acetate (0 -5 m o lm '3) caused a considerable acidification o f(More)
New homogeneous enzyme immunoassays have been developed for cortisol, digoxin, digitoxin, theophylline, phenytoin, and phenobarbital using the cloned enzyme donor immunoassay technology. As applied to Boehringer Mannheim/Hitachi analysis systems these methods provide rapid, accurate and precise quantification of analytes, with minimal interferences from(More)
Previously, monodisperse and sequence-controlled oligo(amidoamine) scaffolds were synthesized based on the step-wise assembly of tailor-made building blocks on solid support that allow for the multivalent presentation of sugar ligands. Here we extend on this concept using a split & combine approach to gain access to a library of linear and branched(More)
