一般說明

全-反式-虾青素属于类胡萝卜素。全反式虾青素是酮式类胡萝卜素，常见于海洋和水生动物，包括磷虾、野生鲑鱼、虹鳟鱼、微藻、龙虾壳、虾[1]、[2] 海产品等。[2] 在生物学上将其称为维生素A 前体，具有强大的抗氧化性能，抗氧化能力比维生素E和 β-胡萝卜素大得多。 它在食品行业和医药行业的作用也十分明确。[3]

應用

全反式虾青素可作为分析参考标准品，用于：
  • 使用高效液相色谱（HPLC）结合质谱[1] 和荧光检测（HPLC-FLD），定量微藻（绿藻）和雨生红球藻（ Haematococcus pluvialis ）中的分析物。[4]
  • 使用高效液相色谱（HPLC）和光电二极管阵列检测（PDA）定量哈氏仿对虾（Parapenaeopsis hardwickii ）中的分析物。 [2]

生化／生理作用

虾青素是在海藻、红酵母和许多植物和动物来源中发现的强效类胡萝卜素抗氧化剂。动物试验表明，它可降低血糖并改善糖尿病代谢综合征的若干指标。可改善高血型模型的血流和血管张力。体外研究表明，它上调间隙联接蛋白 43，可用于化学防癌。

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.
      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 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
