R27 Dye

Dr. Patrick Durkin — Thu, 27 Nov 2025 10:12:35 +0000

R27 is a light stable benzothiazolium/pyridinium-based dye which finds application in the detection of double stranded DNA. This offers a more stable alternative to SYBR Green I and LC Green Plus, displaying almost no degradation of fluorescence after prolonged exposure (over 6 h) at temperatures up to 95 °C when used in a LightCycler® system for PCR.

Bis(1-butylpentyl)decane-1,10-diyl diglutarate

Dr. Patrick Durkin — Fri, 25 Mar 2022 10:41:22 +0000

Bis(1-butylpentyl)decane-1,10-diyl diglutarate is a neutral ionophore that can be used to prepare sodium optode membranes. These can be used to measure total sodium concentration in human blood plasma. This can also be used as a nitrite-selective membrane electrode, for the determination of NAD(P)H coenzymes.
