Description générale

Glass has a density of 2.5 g/cc and is the most commonly used bead media for ′Beadbeating′. Beads are sold in one pound bottles.

Application

  • Extraction of Diatom DNA from Water Samples and Tissues.: This study details a method for extracting DNA from diatom samples using glass beads to enhance the mechanical disruption of cell walls, facilitating the efficient recovery of high-quality DNA for downstream applications (Zhou YC et al., 2023).
  • Combination of direct boiling and glass beads increases the purity and accuracy of bacterial DNA extraction.: The research presents an improved bacterial DNA extraction technique combining direct boiling with glass beads, resulting in higher purity and accuracy of the extracted DNA, which is crucial for precise molecular analyses (Li S et al., 2023).
  • Solvent Precipitation SP3 (SP4) Enhances Recovery for Proteomics Sample Preparation without Magnetic Beads.: The study explores the use of solvent precipitation SP3 with glass beads, offering an efficient alternative for proteomics sample preparation, yielding better protein recovery compared to magnetic beads (Johnston HE et al., 2022).
  • Efficient isolation of brain capillary from a single frozen mouse brain for protein expression analysis.: This research demonstrates an optimized method for isolating brain capillaries from frozen mouse brains using glass beads, enabling detailed protein expression analysis critical for neuroscience research (Ogata S et al., 2021).

Questions

1–4 of 4 Questions  

  1. How is shipping temperature determined? And how is it related to the product storage temperature?

    1 answer

    1. Products may be shipped at a different temperature than the recommended long-term storage temperature. If the product quality is sensitive to short-term exposure to conditions other than the recommended long-term storage, it will be shipped on wet or dry-ice. If the product quality is NOT affected by short-term exposure to conditions other than the recommended long-term storage, it will be shipped at ambient temperature. As shipping routes are configured for minimum transit times, shipping at ambient temperature helps control shipping costs for our customers. For more information, please refer to the Storage and Transport Conditions document: https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/marketing/global/documents/316/622/storage-transport-conditions-mk.pdf

  2. How can I determine the shelf life / expiration / retest date of this product?

    1 answer

    1. If this product has an expiration or retest date, it will be shown on the Certificate of Analysis (COA, CofA). If there is no retest or expiration date listed on the product's COA, we do not have suitable stability data to determine a shelf life. For these products, the only date on the COA will be the release date; a retest, expiration, or use-by-date will not be displayed.
      For all products, we recommend handling per defined conditions as printed in our product literature and website product descriptions. We recommend that products should be routinely inspected by customers to ensure they perform as expected.
      For products without retest or expiration dates, our standard warranty of 1 year from the date of shipment is applicable.
