The present invention provides methods, compositions, mixtures and kits utilizing 5-Chloro-2-methyl-4-isothiazolin-3-one in sequencing reactions, and in particular, sequencing reactions where deoxynucleoside triphosphates comprising a 3'-O position capped by a disulfide-based 3&#x2032;-terminator group are used. In one embodiment, the deoxynucleoside triphosphates comprise a 3&#x2032;-O position capped by a group comprising methylenedisulfide as a cleavable protecting group and a detectable label reversibly connected to the nucleobase of said deoxynucleoside. In addition, thiol-containing compounds and scavengers of thio-containing compounds are described. Such compounds provide new possibilities for future sequencing technologies, including but not limited to Sequencing by Synthesis.
