General description

Phosphate buffered saline with TWEEN® 20, or PBS-T, is primarily used in immunoassays as a washing and blocking buffer. The phosphate buffer maintains a stable pH 7.4, suitable for many biological reactions and assays. The salt or saline solution in PBS-T provides the necessary ionic strength for optimal protein solubility and stability. The addition of 0.05% TWEEN 20, a non-ionic detergent, helps reduce background signals by blocking non-specific binding sites on proteins. PBS-T buffer enhances the washing efficiency by removing unwanted substances and limits non-specific antibody binding sites, while preserving the integrity of the target proteins.

Application

Phosphate buffered saline has been used in:

  • western blotting
  • enzyme-linked immunosorbent assay (ELISA)[1]
  • telomere-FISH (Tel-FISH) and telomere/immunostaining-FISH (Teli-Fish)[2][3][4]
  • cell isolation[5]

Packaging

Foil pouches

Reconstitution

Contents of one pouch dissolved in 1 L dH2O or ultrapure water to yield 0.01 M phosphate buffered saline, 0.138M NaCl, 0.0027M KCl, and 0.05% Tween 20, pH7.4.

Questions

1–3 of 3 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.
