一般描述

L-天冬酰胺是一种天然存在的氨基酸,存在于各种蛋白质中。它用于各种应用的实验室研究,包括细胞培养、蛋白质生物化学和氮代谢研究。它在水中的溶解度和作为天冬酰胺来源的作用使其成为研究生物过程和化学合成的多功能工具。 此外,蛋白质中的 L-天冬酰胺残基对于蛋白质稳定性、折叠和相互作用至关重要。

应用

L-天冬酰胺用于细胞培养基中,是MEM非必需氨基酸溶液的一种组成成分。L-天冬酰胺已被证明可在培养的人结肠腺癌Caco-2细胞和IEC-6肠上皮细胞中增强鸟氨酸脱羧酶的活性。在L-天冬酰胺存在下,枯草芽孢杆菌中的孢子萌发会有所增加。来自非动物来源的L-天冬酰胺是一种蛋白原氨基酸,可用于治疗性重组蛋白和单克隆抗体生产的生物制造的细胞培养系统。它还可作为用于培养人呼吸道上皮细胞的LHC基础培养基的一种组分。[1]

生化/生理作用

氨基酸L-天冬酰胺是L-天冬氨酸的一种结构类似物,其中羧酸部分的侧链被酰胺化后得到了末端胺基。[2]这使得L-天冬酰胺在生理pH下呈中性。天冬酰胺的酰胺基团来自于谷氨酰胺[3],天冬氨酸和谷氨酰胺在ATP存在下的反应产生了天冬酰胺和谷氨酸。在体内,天冬酰胺通过天冬酰胺酶水解成天冬氨酸和NH4+[4]天冬酰胺也是糖肽键中的一种重要氨基酸,通过与糖环的N-糖基键连接。

特点和优势

Questions

1–3 of 3 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.
      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

  3. Does L-Asparagine monohydrate soluble in Phosphate Buffer Saline ?

    1 answer
    1. Information available for the solubility of L-asparagine monohydrate in phosphate-buffered saline (PBS) is sparse. From the data available from a couple sources, the solubility of L-asparagine monohydrate in PBS should be between 5-10 mg/mL. This solubility increases as the temperature increases.
