Beschrijving
MOPSO-natriumzout is een zwitterionisch bufferzout met de empirische formule C₇H₁₄NaNO₅S, CAS-nummer 79803-73-9 en een molaire massa van 247,28 g/mol. Geleverd als PUFFERAN®-kwaliteit met een zuiverheid van minimaal 98 %. De natriumzoutvorm lost gemakkelijk op voor stamoplossingen en werkoplossingen die worden gebruikt bij pH-gecontroleerde experimenten. Dit PUFFERAN®-materiaal van fabrikant Carl ROTH ondersteunt life-science workflows waarvoor Good's-buffers met een gedefinieerde samenstelling nodig zijn. Laboratoria gebruiken MOPSO-natriumzout bij enzymtesten, celkweekgerelateerde buffering en analytische procedures waarbij een stabiele pH-controle nabij het nuttige bereik van de verbinding vereist is. De verpakkingsgrootte is praktisch voor methodeontwikkeling en routinematige bufferbereiding. De gedocumenteerde CAS-identiteit en de specificatie voor minimale zuiverheid helpen de consistentie tussen batches te waarborgen in onderzoeks- en kwaliteitscontroleomgevingen waar met biologische monsters wordt gewerkt.
Dit artikel hoort bij Biologische buffers (Tris, HEPES, MOPS), in Buffers & pH-oplossingen.

Questions about MOPSO natriumzout, PUFFERAN®, min. 98 %, 25 g, kunststof
What is this article?
MOPSO natriumzout, PUFFERAN®, min. 98 %, 25 g, kunststof is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Biological buffers (Tris, HEPES, MOPS), inside Buffers & pH solutions, in Chemicaliën.
Tris, HEPES, MOPS and their relatives hold pH in a range that cells and proteins tolerate, with a pKa near the working pH. The useful range is roughly one unit either side of the pKa. A phosphate buffer and Tris are not interchangeable in a method that names one of them, because the ion itself has effects.
A buffer resists a change in pH when a little acid or base is added. It does that because a weak acid and its conjugate base are both present. A pH buffer used to calibrate a meter has a stated value at a stated temperature. A biological buffer such as Tris or HEPES is chosen because it holds the pH of a living system and does not poison it. Conductivity standards are the sister articles for a conductivity meter. The ions are on PubChem. Electrode calibration practice sits with EURAMET and BELAC.
