General description

We are committed to bringing you Greener Alternative Products, which adhere to one or more of the 12 Principles of Green Chemistry. This product has been enhanced for catalysis. Click here for more information.

Application

Hydrogen peroxide has been used for immunocytochemistry for eNOS. It has also been used for developing colour during detection of anti-prothrombin and anti-beta2-glycoprotein I antibodies. Additionally, it has also been used as a supplement in Hanks buffered saline solution for assessing the functional activity of myeloperoxidase.

Biochem/physiol Actions

Hydrogen peroxide (H2O2) is a strong oxidizer that can induce neuronal death in cultured cortical neurons via an apoptotic pathway. Oxidative burst facilitated by hydrogen peroxide is a key mechanism of plant defense during an incompatible interaction. Hydrogen peroxide injected in transgenic rice induces cell death as well as increase resistance to both bacterial and fungal pathogens.

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

  3. 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
