For labs in high-volume settings, repeated thawing is inevitable. The ADN432 New ships with an optimized buffer containing a non-toxic cryo-protectant. This allows the reagent to withstand up to 50 freeze-thaw cycles (tested at -20°C to room temperature) with less than 5% loss in fluorescent intensity. Previously, the threshold was 10 cycles.

The original compound began to lose efficacy after 15 thermal cycles above 95°C. The ADN432 New variant utilizes a novel ethidium-based linker that tolerates up to 50 standard PCR cycles without signal degradation. This is a game-changer for nested PCR and long-amplicon sequencing. For labs in high-volume settings, repeated thawing is

To understand why the ADN432 New version is so critical, we must first revisit the original. ADN432 is a proprietary, high-affinity DNA-binding dye or probe conjugate (depending on the specific supplier's catalog, it is often classified under "Advanced Detection Nucleotides"). The legacy ADN432 was widely adopted for:
However, users reported two consistent pain points with the original formula: degradation after repeated freeze-thaw cycles and some cross-reactivity with GC-rich secondary structures. Enter the ADN432 New.
