  • Spex NanoSNAP™

    May 25 2022

    New Spex NanoSNAP provides high performance measurements of nucleic acids and proteins in a snap

    Metuchen, NJ— Scientists have a faster way to find the purity of DNA, RNA and proteins. The new Spex® NanoSNAP is a high-speed microvolume spectrophotometer that provides fast measurements and high throughput. It is dedicated to life sciences applications but also provides additional methods for self-defined protocols such as spectrum scanning, multiwavelength, quantitation and concentration.

    This new spectrophotometer assesses the purity of DNA, RNA, proteins and any other type of assay for samples available in small quantities within seconds, using as little as 1 μL of sample with no dilution required. It is versatile, with full wavelength coverage from 190 to 1000 nm. It combines high performance along with ease of use thanks to its nano hydrophobic coated sample window, LED viewing light and the cushioning design of the detection arm. Reports are saved on the internal memory and can be easily transferred to USB.

    The integrated 7-inch, color touch screen displays an intuitive graphic interface that makes navigation between the different measurement modes easy to learn and quick to use. Multiple measurement modes are available:

    • Nucleic acids concentration and purity: dsDNA, RNA, ssDNA
    • Protein A280: BSA, IGG, lysosome and custom proteins
    • Protein assays: BCA, Bradford, Modified Lowry for protein standard curve protocols
    • OD 600: Optical density at 600 nm and cells/mL calculation for cell cultures
    • More assays: Customized protocols using factor, standard curve and UV-Vis method

  • New Spex® Genomax® 2050 Homogenizer and Lyser Expediates the Extraction Process

    Oct 21 2021

    Obtain fast and efficient extraction of nucleic acids, proteins, and other molecules with the new Spex® Genomax® 2050; a high-throughput plant and animal tissue homogenizer and cell lyser designed for rapid cell disruption, cell lysis and tissue homogenization through bead beating. It is ideal for DNA/RNA and protein extraction in clinical, pharmaceutical and biological applications.

    The Genomax 2050, with its useful features, is easy to use. The touch screen interface allows users to set, and store run time, operating rate, pause time and cycles. Protocols can be passcode protected. The Genomax comes pre-loaded with one-touch protocols for plant and animal tissue homogenization.

    For added convenience and efficiency, the 2051 General-Purpose Clamp is supplied with the Genomax for processing vials, tubes, and jars, ranging from 1 mL to 750 mL. Spex Genomic DNA Isolation Kits are available for extraction and purification of DNA from animal and plant tissues.

    These DNA isolation kits allow for fast and seamless isolation of DNA from a wide variety of animal tissues and cells, including mammalian, poultry, fish, and soft and tough plant tissue. The kit combines the use of chaotropic salts and detergents to disrupt animal tissues or cells permitting the selective binding of DNA to a silica column. Proteinase K and RNase A are then added to implement DNA isolation. An ethanol wash buffer is used to remove any additional elements or contamination from the silica column. The column is dried by centrifugation and DNA is eluted using the elution buffer.
