After separation, nonradioactive, optical polyP staining is limited to chain lengths greater than 15 monomers with toluidine blue or 4\u2032,6\u2010diamidino\u20102\u2010phenylindole. PolyP chain lengths longer than 62monomers were correlated to the shortest DNA ladders. In this study, synthetic linear polyPs (Sigma\u2010Aldrich \u201cType 45\u201d, estimated mean length of 45  monomers), trimetaphosphate (trimetaP: 3  ring), tripolyphosphate (tripolyP), pyrophosphate (PP\n                    <jats:sub>i<\/jats:sub>\n                    ), and inorganic orthophosphate (o\u2010P\n                    <jats:sub>i<\/jats:sub>\n                    ) were visualized after separation by an\n                    <jats:italic>in situ<\/jats:italic>\n                    hydrolytic degradation process to o\u2010P\n                    <jats:sub>i<\/jats:sub>\n                    that was subsequently stained with methyl green.
