Abstract:
A method for agglutination detection using optical imaging of reaction wells containing agglutination objects in a programmable random access automated apparatus for perforing agglutination assays is provided. An image of the agglutination objects in the reaction wells is taken with analyzation of the intensity values and transitions through relative portions of the image and background which provides intensity values suitable for classifying. The method utilizes slope information from a derivative (Fig. 34 A-E, second row) rather than absolute intensities, thus allowing scoring algorithm based on slope total information. The agglutination detection method uses a CCD camera to take an image at each well (Fig. 34 A-E, first row) of a multiple well cartridge, thus providing information suitable for analyzing from the image detection apparatus, the apparatus processes the information to generate a visual indication of the results of the assays being performed. A micro-processor is provided to assist in the operation of the apparatus as well as the image processing data collection and analysis.
Abstract:
Novel silyl alcohols having bulky substituents bonded to the silicon, and the silyl group attached to a carbon include the preferred 2-silyl-ethan-1-ols. A method for synthesizing silyl substituted alcohols include hydrosilation of a vinylic ester, especially vinyl acetate, followed by hydrolysis in mild base. The silyl alcohols are useful in preparing phosphorylating reagents for phosphorylating an oligonucleotide. The phosphorylated intermediate bearing the silyl group may be separated from failure product on the basis of bulky substituents on the silyl protecting group, which is later removed, e.g. by fluoride ion.

Abstract:
A retortable high panel strength plastic container (10) that includes a sidewall (11) and a bottom wall (12). The container (10) has a recessed circular center portion (17) in the bottom wall (12) that is designed to facilitate the volumetric changes that occur in the container during sterilization. These volumetric changes occur without catastrophic failure. Examples of containers having this feature are disclosed as well as the cross-sectional profile of the recessed circular center portions of the bottom walls of the containers.

Abstract:
Methods and test kits for detecting the presence of an analyte in a test sample on a molecule-by-molecule basis by using scanning probe microscopy, in which the test sample suspected of containing the analyte of interest is exposed to a test piece to which an analyte specific substance has been attached, and the test piece is scanned by scanning probe microscopy to determine the presence or absence of the analyte.
Abstract:
Novel bacterial isolates of B. thuringiensis are having enhanced toxicity with respect to previously resistant or insufficiently susceptible insect species, including, but not limited to, Plutella xylostella, Spodoptera frugiperda and Spodoptera exigua, as well as certain secondary pests such as Trichoplusia ni. Such isolates may be characterized by their possession of a particular subset of the genes coding for the various B. thuringiensis delta -endotoxin proteins and by a characteristic plasmid profile, or array, known to be associated therewith. Also disclosed are a method for the efficient identification of such bacterial isolates utilizing generalized or, alternatively, gene-specific DNA probes; cloned or synthesized nucleotide sequences which are useful in the preparation of those probes; compositions containing an insecticidally effective amount of a bacterial isolate of the invention in combination with an acceptable carrier; and a method for the use thereof in the control or eradication of insect pests.
