General description

Activated streptavidin (SA) and horseradish peroxidase (HRP) are covalently conjugated to a polymer backbone. Multiple active biomolecules on each polymer chain increase the biotin binding capacity and amplify the peroxidase enzyme signal.

Application

Detection of biotinylated proteins and nucleic acids and other biomolecules.
Suitable use in Western blotting and ELISA and for detecting surface antigens in immunohistochemistry and immunocytochemistry.

Biochem/physiol Actions

Biotinylated biomolecules.

Physical form

Supplied as an 1.0 mg/ml solution in 0.01 M sodium phosphate, 0.15 M sodium chloride, 50% glycerol, stabilizer and preservative, pH 7.4.

Storage Class

10 - Combustible liquids

Questions

1–3 of 3 Questions  

  1. 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.
      For more information, please refer to the Product Dating Information document: https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/marketing/global/documents/418/501/product-dating-information-06-25-mk.pdf

  2. 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

  3. Hi, regarding S2438 is there any information on the length of the polymer and how many HRP and streptavidin molecules each polymer contains?

    1 answer

    1. Unfortunately, the length of the polymer and the number of peroxidase and streptavidin molecules are not determined.
