CAS:Phenol red is a pH indicator that finds broad applications from chemistry to microbiology. Colour varies from yellow at pH<6.8 (lmax 443nm) through to light red/pink at 6.8<pH<8.2 (lmax 570 nm) to vivid purple/red at pH>8.2. It is widely used in cell culture to monitor pH and for colorimetric titration. For example, phenol red can be used to quantify Br- content in sea or fresh water. It is added to VTM as pH indicator, at the concentration of 10mg/ml, maintaining a pink colour at neutral pH.Fórmula:C19H14O5SForma y color:PowderPeso molecular:354.38 g/molWST-5
CAS:WST-5 is a colourless compounds which become coloured when reduced to WST-5 formazan forming a blue colour. Traditionally used as an indicator of cell metabolism in eukaryotes and prokaryotes, WST-5 functions as an artificial electron acceptor and thus detects dehydrogenase activities. The production of coloured formazan is irreversible and can be quantified using spectrophotometry.Fórmula:C52H46N12O16S6•Na2Pureza:Min. 95%Forma y color:PowderPeso molecular:1,333.37 g/mol4-(Dicyanomethylene)-2-tert-butyl-6-(1,1,7,7-tetramethyljulolidin-4-yl-vinyl)-4H-pyran
