Application
Il bicarbonato di sodio è stato utilizzato:
- come componente del sistema di coltura degli embrioni bovini durante la maturazione, fertilizzazione e coltura in vitro (IVMFC)[1]
- come componente di una miscela 1:1 di terreno Eagle modificato di Dulbecco e miscela nutritiva di Ham F-12 durante la coltura di cellule endoteliali microvascolari bovine[2]
- come componente del terreno ITS (insulina, transferrina e selenite) utilizzato durante l′isolamento dei neuroni dopaminergici in cellule staminali embrionali umane[3]
- come componente del terreno utilizzato per la coltura cellulare di cellule renali embrionali umane[4]
- come componente della soluzione di scongelamento di Beltsville utilizzata per diluire lo sperma[5]
General description
Il bicarbonato di sodio trova ampio impiego come tampone fisiologico nelle applicazioni per colture cellulari. Il pKa per la reazione bicarbonato <-> acido carbonico è 6,4. Il pKa per la reazione bicarbonato <-> carbonato è 10,3. Il bicarbonato di sodio ha due pKa: 6,4 e 10,3. È adoperato diffusamente come tampone fisiologico nelle applicazioni in vitro.

Nonylphenols (NP) are ubiquitous substances that have been detected in highly diverse foodstuff. As breakdown products of nonylphenol ethoxylates, NP could end up in the aquatic environment. This article presents a rapid method for NP detection in surface water by planar solid phase extraction – planar yeast estrogen screen (pSPE-pYES).

This product is not assigned an expiration date. It is assigned a recommended retest date of approximately 5 years after the quality release date. A recommended retest date is the period of time during which the product is expected to remain within established stability specifications, provided that it has been stored under defined conditions. After the Retest Date, product samples should be examined to ensure that the product is still in compliance with the established specifications. For more information, you may access the "Product Dating Information" document under "ADDITIONAL USEFUL DOCUMENTS ABOUT OUR PRODUCTS" at the bottom of the Quality Services page with this link: https://www.sigmaaldrich.com/US/en/life-science/quality-and-regulatory-management/quality-services.
After opening, various factors may influence the performance of the product. Moisture uptake and cross-contamination are common issues that are dependent on product handling and storage. If the product you are using is experience stability issues before the recommended restest date, this reporting should be investigated by our Technical Service team who can assist you with further troubleshooting and/or investigation. We kindly ask you to navigate to the link https://www.sigmaaldrich.com/techservice, click on "Report Product Issues" under the Products Section with all the required information so that a member of our team can reach out to you to assist further. Thank you.
