This paper presents new self-quenching DNA probes that exploit the efficient fluorescence quenching by the formation of dye dimers. The probes consist of a hairpin-structured oligonucleotide that is labeled with two identical fluorescence dyes that are able to form non-fluorescent H-type dimers while the hairpin is closed. We used the oxazine derivative MR 121 that has a sufficient dimerization tendency and can be excited by a pulsed diode laser emitting at 635 nm. Upon hybridization to t
