应用

L-胱氨酸已被用作星形胶质细胞条件培养基的补充剂,用于培养脑星形胶质细胞。[1]它已被用于多种技术,如HPLC-FD、UHPLC-UV、UHPLC-MS和三重四极杆串联质谱(UHPLC-MS/MS),以区分蓝藻神经毒素BMAA(β-N-甲基氨基-L-丙氨酸)与其他二氨基酸。[2]
L-胱氨酸已被用作卵母细胞培养基的补充剂,用于改善卵母细胞成熟和胚胎发育的单性生殖。[3]

生化/生理作用

胱氨酸尿症的特征在于L-胱氨酸的肾转运和排泄。[4]半胱氨酸是与生长、繁殖、维持和免疫相关的功能性氨基酸之一。半胱氨酸是蛋白质中二硫键的来源,并且与硫转运有关。在生理pH下,半胱氨酸经过快速氧化,形成胱氨酸。[5]半胱氨酸或胱氨酸的可用性降低,会影响白细胞代谢。[6]L-胱氨酸是动脉平滑肌细胞的氧气产生和LDL(低密度脂蛋白)修饰所必需的。

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
