Aplicación

La quitina del caparazón de las gambas es adecuada para el análisis de la quitinasa. Es un polisacárido compuesto por N-acetil-D-glucosamina que también puede utilizarse para la fabricación de glucosamina y quitosano.
La quitina del caparazón de las gambas, un polímero de cadena larga de restos de N-acetilglucosamina unidos por enlaces β-1,4, puede utilizarse para estudiar sus propiedades fisicoquímicas y su papel en la formación de los exoesqueletos de los artrópodos. Puede utilizarse para identificar y caracterizar las quitinasas y las deacetilasas de quitina y como control para estudiar la estructura de las quitinas de otras especies. Puede utilizarse en la investigación de la alergia y el asma causados por la quitina. La quitina puede utilizarse como agente de viscosidad/engrosador o litigante.

Calidad

Requiere purificación antes de su utilización como sustrato de la quitinasa.

Questions

1–5 of 5 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.

  5. Can you please tell me the size of the product Chitin from shrimp shells ( C7170). Can I use the Chitin for flow cytometry experiment? or do you have a smaller size of Chitin?

    1 answer

    1. Unfortunately, the particle size of this product, as well as the alternative C9752, has not been determined. These items are not tested for a specific application, including flow cytometry. Currently, the C7170 and C9752 are the only chitin products available.
