General description

Dibutyl phthalate (DBP) is most commonly used as a plasticizer in a variety of household products. It has the ability to leach and evaporate into the environment while using or disposing of these products.[1][2] Therefore, studies are being conducted to assess its toxic and apoptotic effects.[1] Studies have also indicated that exposure to high doses of DBP may interfere with progesterone and estradiol production.[2]

Dibutyl phthalate impairs steroidogenesis and a subset of LH-dependent genes in cultured human mural granulosa cell in vitro.

Reproductive Toxicology, 69, 13-18 (2017)
Dibutyl phthalate (DBP)-induced apoptosis and neurotoxicity are mediated via the aryl hydrocarbon receptor (AhR) but not by estrogen receptor alpha (ER?), estrogen receptor beta (ER?), or peroxisome proliferator-activated receptor gamma (PPAR?) in mouse cortical neurons.

Assays to monitor the metabolic state or nutrient uptake capacity of immune cells at a single cell level are increasingly in demand. One assay, used by many immunologists, employs 2-(N-(7-Nitrobenz-2-oxa-1,3-diazol-4-yl)Amino)-2-Deoxyglucose (2-NBDG), a fluorescent analogue of 2-deoxyglucose (2DG), as a substrate

Aquatic toxicology (Amsterdam, Netherlands), 149, 103-115 (2014-03-01)
Phthalic acid esters (PAEs) are a class of synthetic industrial chemicals commonly found in the aquatic environment worldwide. PAEs have been recognised as anti-androgens in male mammals but little is known about their endocrine disrupting effects in fish. This study

Questions

1–4 of 4 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

  4. Buenos días, Me gustaría confirmar si el formato "poly bottle" se trata de una botella de plástico y en su caso, si existe algún tipo de diferencia entre los formatos de 25 y 100 mL, puesto que la diferencia de precio es mínima.

    1 answer

    1. Item 524980-25ML is packaged in a HDPE plastic bottle and 524980-100ML is packaged in an amber glass bottle.
