一般描述

锌是生物体内含量最丰富的微量金属之一，参与神经系统发育、核酸代谢和信号转导等多种生物学功能。锌被用作许多酶的辅助因子，如碳酸酐酶，它对二氧化碳调节和羧肽酶，分解肽键很重要。[1][2]参与多种细胞过程，如免疫功能、创伤愈合、蛋白质合成、DNA 合成及细胞分裂等。[1]锌可促进妊娠期、儿童期和青春期的正常生长和发育。它还表现出抗氧化性，并对正常的味觉和嗅觉至关重要。[1]

适用性

适用于测量各种样本中的锌浓度，包括血清、血浆、尿液或脑脊液 (CSF)。

原理

锌测定试剂盒为测定各种样本（包括血清、血浆、尿液或脑脊液 (CSF)）中的锌提供了一种简单直接的程序。锌离子与配体结合，生成与锌含量成比例的比色 (560 nm) 产物。

Questions

1–2 of 2 Questions  

  1. 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

  2. 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.
