Application

Phosphocreatine disodium salt hydrate has been used:
  • as a component: of Xenopus buffer (XB) buffer to remove the membrane-bound proteins[1]
  • of M5+ buffer to perform polarized total internal reflection fluorescence (polTIRF) experiments [2]
  • of ATP regenerating system for 7-nitro-2-1,3-benzoxadiazol-4-yl phospholipid(NBD-PL) translocation assay[3]

Biochem/physiol Actions

Phosphocreatine disodium salt hydrate is useful to study nasopharyngeal carcinoma cells and induced temporary cardiac arrest. It also evaluate the effects of adenosine A(2A) receptor modulation in the nucleus accumbens on cocaine seeking in rats.
Phosphocreatine is widely known for its quickest form of regeneration using enzyme creatine kinase. It functions as a temporal energy buffer. Phosphocreatine is present in muscle tissues and plays a major role in maintaining energy homeostasis in muscle cells.[4]
Phosphocreatine, a high-energy phosphate reservoir in vertebrate and some invertebrate muscles, provides phosphate for ADP-ATP conversion.

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.
      For more information, please refer to the Product Dating Information document: https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/marketing/global/documents/449/386/product-dating-information-mk.pdf

  3. Va bene come Fosfocreatina?

    1 answer

    1. The sodium form of phosphocreatine, in equimolar quantities, is comparable to the free form in biological activity. The sodium form demonstrates a higher solubility rate in water. Certain applications may require a specific form, which would have to be determined by the end user.
