Beschrijving
POPSO, PUFFERAN® is een zwitterionische bufferstof van hoge zuiverheid, geleverd met min. 99 % voor toepassingen in de moleculaire biologie en de life sciences. De empirische formule is C₁₀H₂₂N₂O₈S₂ · 2 H₂O, met een molaire massa van 398.5 g/mol en CAS-nummer 68189-43-5 (EG nr. 269-199-1). POPSO behoort tot de familie van buffers van het Good’s-type die worden gebruikt om een stabiele pH te handhaven in biochemische assays, enzymwerk, celgerelateerde bereidingen en andere waterige systemen waarin minimale metaalbinding en een betrouwbare buffercapaciteit voordelig zijn. Het product is PUFFERAN®-kwaliteit onderstreept de positionering ervan onder specifieke reagentia voor moleculaire biologie. Verkrijgbaar van fabrikant Carl ROTH, integreert het in workflows voor reagentia die worden gebruikt in de moleculaire biologie en de bufferbereiding. Gedocumenteerd CAS, EG-nummer en molaire massa ondersteunen nauwkeurig afwegen, oplossingsberekening en kwaliteitsdocumentatie zonder beroep op niet-gespecificeerde prestatieclaims.
Dit artikel maakt deel uit van Biologische buffers (Tris, HEPES, MOPS), in Buffers & pH-oplossingen.

Questions about POPSO, PUFFERAN®, min. 99 %, 25 g, kunststof
What is this article?
POPSO, PUFFERAN®, min. 99 %, 25 g, kunststof is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Biologische buffers (Tris, HEPES, MOPS), inside Buffers & pH-oplossingen, 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.
