General description
Il Tris base può essere utilizzato come standard nelle titolazioni acido-base, come tampone a sé o come componente di formulazioni tampone, come, tra le altre, il tampone Tris-EDTA (TE), il tampone TAE o il tampone TBE. Il Tris base mostra purezza elevata, stabilità cruciale e una natura relativamente non igroscopica, il che ne fa una soluzione affidabile per gli ambienti di laboratorio. In questi contesti, è indispensabile per la preparazione di tamponi compatibili con i fluidi biologici, fungendo da soluzione standard di calibrazione del pH. È di aiuto in svariate procedure quali il saggio della lattato deidrogenasi, l′ibridazione in situ e l′estrazione delle proteine dalle cellule. La sua versatilità è apprezzata anche nei laboratori di colture cellulari, biochimica e biologia molecolare, ambiti in cui risulta utile in studi che interessano la permeabilità delle membrane cellulari e la preparazione di tamponi.
Application
- come componente del tampone H (tampone per la dissociazione cellulare)
- per il lavaggio e la saturazione dei pozzetti nel saggio immunoenzimatico ELISA a doppio sandwich[1]
- come tampone del test per la ricostituzione di campioni proteici estratti ed essiccati[2]
- per la preparazione del tampone Tris-HCl utilizzato per stabilizzare le proteine
- come tampone di estrazione del carotenoide dai tuberi
- come componente del tampone del campione nell′estrazione delle proteine per Western blotting[3]
- come componente del tampone del campione per l′elettroforesi su gel di poliacrilammide in presenza di sodio dodecil solfato (SDS-PAGE)
- per la preparazione del fluido corporeo simulato (SBF) per il saggio sul riassorbimento del fosfato di calcio (CaP)
- come tampone per la deposizione della polidopamina (PDA) su un substrato di acciaio inossidabile
Features and Benefits
- Tampone efficace nell′intervallo di pH 7-9 (25 °C), con una pKa di 8,1 (25 °C)
- Sottoposto a test che ne confermano i bassi livelli di contaminazione da metalli pesanti, garantendone l′idoneità ad un ampio ventaglio di applicazioni
- Può essere impiegato in attività di ricerca in biologia cellulare e in biochimica
Packaging
- The current DRYPOUR® packaging configuration is in a 50L nestable drum
- 25KG-DP are the standard prepack offering
- Smaller volumes can be put in the same drum for variable configurations
- Improves operational efficiency by reducing material preparation time and increasing operator safety
- Minimizes caking of hygroscopic salts
- Offers triple protection: against moisture inside and outside, and against contamination
- This state-of-the-art design packaging system minimizes caking, thus significantly reducing the time needed for material preparation
- PE drum with our new tamper-evident seal, a polyethylene liner with integrated desiccant bags and a breathable interior Tyvek® liner
- Desiccant bags are firmly integrated into the polyethylene liner
- Triple protection delivers two invaluable results:
- Dramatically reduced caking
- No contamination risk from the desiccant
Other Notes
Per applicazioni che necessitano estrema precisione, utilizzare un pHmetro accuratamente calibrato con un elettrodo combinato vetro/calomelano.

How can I determine the shelf life / expiration / retest date of this product?
1 answer-
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.

How is shipping temperature determined? And how is it related to the product storage temperature?
1 answer-
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
