  • Publication number: 20220212190
    Abstract: The technology described herein generally relates to microfluidic cartridges. The technology more particularly relates to a compressible pad applied to a microfluidic cartridge, wherein the microfluidic cartridge is configured to amplify nucleotides of interest, particularly from several biological samples in parallel, within microfluidic channels in the cartridge and permit detection of those nucleotides. Compressible pads of the present technology can be implemented in microfluidic cartridges having enhanced reaction chamber volumes, resulting in improved thermal uniformity and amplification efficiency in the cartridge. Assays using microfluidic cartridges of the present technology advantageously exhibit improved limit of detection (LOD) and improved limit of quantification (LOQ).

  • Publication number: 20120167304
    Abstract: The invention is a “blanket ball” or a baby blanket that can be made into the shape of a “soft” ball or other suitable shapes. The blanket is made from two layers of material that are connected together around their periphery. An opening in one of the layers defines a pouch that is normally received or stored between the two blanket layers. The pouch may be reversed and pulled through the opening to create a stuff sack for the remaining portions of the blanket. When the other blanket materials are stuffed into the pouch, it creates a ball shape.

  • Publication number: 20030188338
    Abstract: The present invention relates to isolated Raspberry Bushy Dwarf Virus (RBDV) nucleic acid sequences which encode RBDV coat and movement proteins or polypeptides and mutant or modified forms thereof. The invention further relates to heterologous nucleic acid constructs, vectors, transformation methods, plant cells and plants comprising such RBDV-encoding nucleic acids and methods for inducing resistance to RBDV by transforming plants with a nucleic acid construct comprising RBDV protein or polypeptide-encoding nucleic acid sequences.
