General description

Citrate Buffer Solution, 0.09 M, is a high-quality biochemical buffer solution commonly employed in various research applications. Its applications include use in acid phosphatase reactions alongside p-nitrophenyl phosphate (pNPP) enzyme substrate. Citrate Buffer is also used for the isolation of RNA from cells and tissues.[1] In addition, it is also used as a background electrolyte for separating sulfonamides utilizing capillary zone electrophoresis. With its superior buffering capacity and ability to maintain a stable pH, Citrate Buffer Solution, 0.09 M is an excellent choice for any researcher in need of reliable performance.

Application

Citrate Buffer Solution, 0.09 M has been used as a heat-induced antigen retriever on formalin-fixed paraffin-embedded (FFPE) tissue sections during immunohistochemistry (IHC) experiments.[2][3] It has also been used in the preparation of hybridization solutions for fluorescence in situ hybridization (FISH) procedures.[4]

Other Notes

Unit definition: One unit of acid phosphatase will hydrolyze 1.0 μmole of p-nitrophenyl phosphate per, minute at pH 4.8 at 37 °C.

Questions

1–2 of 2 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
