일반 설명

Calcium chloride is a commonly used reagent in biochemistry. Calcium plays important roles in many biological processes, including signal transduction, muscle contraction, and maintenance of cell membrane and cell wall stability.1,2 Extensive reviews of the experimental measurement of biological calcium have been published.3,4Calcium chloride is used in the preparation and transformation of competent E. coli and in the transfection of eukaryotic cells with either plasmid DNA or high molecular weight genomic DNA.5 The CaCl2-mediated electroporation of E. coli with the plasmid DNA pBR322 has been studied.6 A protocol for the concentration of virus vectors that uses CaCl2 has been published.7CaCl2 has been used in the stabilization and two-dimensional crystallization of the NADH-ubiquinone oxidoreductase (complex I) from Escherichia coli.8 The crystallization of porcine pancreatic elastase in the presence of CaCl2 in the presence of sodium citrate reveals binding of calcium in the metal binding site of the protein.9 The effect of CaCl2 on the total fluorescence in the polymerication of the tubulin-like FtsZ division protein of Escherichia coli has been studied by a multiwell fluorescent assay.10

애플리케이션

This product is insect cell culture tested (0.5 mg/ml) and is appropriate for insect cell culture applications. Calcium chloride is used in the preparation and transformation of competent E. coli and in the
transfection of eukaryotic cells with either plasmid DNA or high molecular weight genomic DNA. The CaCl2-mediated electroporation of E. coli with the plasmid DNA pBR322 has been studied. A protocol for the concentration of virus vectors that uses CaCl2 has been published.

1–3 / 3 질문  
  1. 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

  2. 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.

  3. What is the procedure for preparing a 2 M solution using calcium chloride and calcium chloride dihydrate?

    1 답변
    1. The molecular weight for calcium chloride dihydrate is 147.01 g/mol, so a 2 M solution would be 294 g/L. Similarly, the molecular weight for calcium chloride is 110.98 g/mole, so a 2 M solution would be 222 g/L. Therefore, a 2 M solution of calcium chloride dihydrate (such as C7902) would be 294 g/L with a molecular weight of 147.01 g/mol.
