Product parameters
Use parameters for the exact catalog number when preparing reagents, setting reagent input or calculating results. Request a lot-specific CoA for test results.
Protocol
Diluting the 10,000× concentrate
This product is a fold-concentrated solution; dilute for the corresponding gel workflow. A 10,000× designation is not 10,000 mM and does not use the molar-stock calculation for SYTO 9 or YOYO.
Sample and channel
Prepare a suitable gel, loading standard and imaging system. Check illumination, filters and exposure, avoiding image saturation.
Load and separate
Choose gel, loading and running conditions for fragment size and nucleic-acid type, including standards and blanks.
Titrate this formulation
Use the purchased formulation and instructions for concentration/time series, comparing background, positive separation and saturation.
Acquire and interpret
Compare bands at matched, unsaturated exposure. For quantification, establish a standard curve for the corresponding nucleic acid.

Frequently asked questions
Is SYBR Gold restricted to double-stranded DNA?
SYBR Gold can detect dsDNA, ssDNA and RNA bands in gels. Validate background and response for the nucleic-acid type and gel; a brightness standard for one type does not directly quantify another.
Does a brighter band always mean more nucleic acid?
Brightness also depends on structure, staining and imaging. Use matched standards and unsaturated acquisition for quantification.
Does 10,000× establish a fixed molar concentration?
Fold concentration guides dilution for the intended working solution; it does not establish an unknown molecular weight or molar concentration. Follow this product’s gel workflow and match staining and exposure across samples.
