일반 설명

L-Ascorbic acid 2-phosphate sesquimagnesium salt hydrate, also known as Magnesium Ascorbyl Phosphate (MAP), is a stable derivative of vitamin C (L-ascorbic acid). MAP is applied in various research domains, including emulsion-based experiments, biocatalytic dephosphorylation, cell differentiation, and tissue engineering. Its versatile utility extends to gene repression, transcriptional studies, and investigations related to growth factors. In cell biology, MAP demonstrates potential applications in inducing morphological changes in cultured cells, influencing cell death pathways.

Moreover, MAP plays a pivotal role in metabolomics and biochemical research. Acting as an antioxidant, it effectively scavenges free radicals, offering protection against oxidative damage. Its anti-inflammatory properties contribute to the reduction of inflammation, and studies have indicated its ability to stimulate collagen production. Additionally, MAP serves as a chelating agent, further expanding its applications in various research studies. The multifaceted nature of MAP makes it a valuable tool in scientific investigations, contributing to advancements in cell biology, metabolomics, and biochemical research.

애플리케이션

L-Ascorbic acid 2-phosphate sesquimagnesium salt hydrate has been used in mesenchymal stem cells (MSC) expansion medium to incubate scaffolds,[1] in Dulbecco′s modified eagle medium (DMEM) for culturing human umbilical cord cells[2] and mesenchymal stem cells.[3]

생화학적/생리학적 작용

L-Ascorbic acid 2-phosphate (AA2P) is used in biocatalytic dephosphorylation for electric power generation and electrochemical detection assays. L-Ascorbic acid 2-phosphate may be used in cell differentiation and tissue engineering applications. Asc-2P is used in studies of gene repression, such as the repression of dihydrotestosterone-induced dickkopf-1 expression.

특징 및 장점

  • Can be used in Cell Biology, Metabolomics and Biochemical research

질문

1–10 / 13 질문  

  1. How can I determine the shelf life / expiration / retest date of this product?

    1 답변

    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

  2. How is shipping temperature determined? And how is it related to the product storage temperature?

    1 답변

    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
