Application

Manganese(II) chloride tetrahydrate may be used to accelerate the synthesis of dihydropyrimidin-2(1H)-ones by the condensation of aldehyde, β-dicarbonyl compounds and urea under microwave conditions.[1] It may also be used in the synthesis of manganese(II) tris(2-benzimidazolylmethyl)amine (ntb) complexes.[2]

A series of manganese(II) tris(2-benzimidazolylmethyl)amine (ntb) complexes were synthesized and characterized. In these complexes, ntb functions as a tripodal tetradentate ligand, resulting in trigonal pyramidal geometry. The complexes have five- to seven-coordinate manganese(II) ions depending on the additional ligand used.

We describe a method for the efficient and selective identification of DNA containing the 5-hydroxymethylcytosine (5-hmC) modification. This protocol takes advantage of two proteins: T4 β-glucosyltransferase (β-gt), which converts 5-hmC to β-glucosyl-5-hmC (β-glu-5-hmC), and J-binding protein 1 (JBP1), which specifically

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.

  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
