  • Nucleic acid extraction using organic solvents to remove inhibitors
    Patent number: 10196632
    Abstract: Nucleic acid amplification tests have been widely used in clinical laboratories. Nucleic acid extraction from biological materials is challenging because different unfavorable substances may co-extract and inhibit downstream applications. The present invention relates to a composition of and a method for treating the sample prior, during or post extraction of nucleic acid. More specifically, the claimed invention relates to a composition of and a method for using low concentrations of common organic solvents to remove inhibitors of nucleic acid amplification. The present invention can be used for extracting nucleic acids (DNA/RNA) from bacteria, viruses, parasites, and other biological materials or matrices, including but not limit to, stool samples, body fluids, plants and cultures. The method is rapid, low-cost, and easy to use in a laboratory setting. The nucleic acid extracted in accordance with the invention can be used for nucleic acid amplification reactions.

  • Front rack for a truck
    Patent number: 4953757
    Abstract: A truck rack mounted over the cab allows for front loading. A ramp lowers down to allow for easy loading. A winch and pulley can be provided for easing the actual lifting of the load along the ramp. The ramp lifts back up to hold the load in place above the cab.
