應用

高分子量聚-γ-谷氨酸（γPGA）被证明可以在C57BL/6小鼠中增加NK细胞介导的细胞毒性水平以及 INF-γ分泌。[1] 已经评估了可生物降解的γ-PGA纳米颗粒作为抗原递送载体[2] 以及递送流感病毒血凝素（HA）疫苗的应用。[3] γ-PGA的其他生命科学应用包括用于可生物降解的纤维和纳米纤维片、水凝胶和冷冻保护剂。[4][5][6]

其他說明

高分子量聚-γ-谷氨酸是一种谷氨酸聚合物，由α-氨基和γ-羧基之间的酰胺键连接。 γ-PGA是由芽孢杆菌发酵产生的。该亚基主要是L-异构体。

This review article deals with the chemistry and biosynthesis of poly-(gamma-glutamic acid) (gamma-PGA) produced by various strains of Bacillus. Potential applications of gamma-PGA as thickener, cryoprotectant, humectant, drug carrier, biological adhesive, flocculant, or heavy metal absorbent, etc. with biodegradability in

Ultra-high-molecular-weight poly-gamma-glutamic acid (gamma-PGA) is a most promising biodegradable polymer that is produced by Bacillus subtilis (chungkookjang). Attractive properties of gamma-PGA are that it is water soluble, anionic, biodegradable, and edible. Development of gamma-PGA has pursued in terms of cosmetics/skin

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
