REAGENT SUBTYPE
Compare DNA ladders: 1 kb DNA ladders: Extended-range 1 kb ladders within Molecular weight standards. This category groups catalog records by experimental role and format.
Molecular weight standards provide reference bands for interpreting electrophoresis results.
The 1 kb family is indexed separately from 100 bp ladders. Compare the actual band range and spacing, reference-band intensity and loading formulation; different 1 kb products may have different band patterns.
When selecting products, compare band pattern, useful size range, loading formulation and detection method.
Use the narrower categories to separate experimental requirements before comparing individual products. Products across this broader branch can serve different steps or use different formats.
DNA ladders / 1 kb DNA ladders / Extended-range 1 kb ladders / Ready-to-load ladders
Ready-to-load DNA ladder with 13 fragments spanning 250 bp to 10 kb; includes 1 kb and 3 kb reference bands. Review the manufacturer protocol before substituting.
DNA ladders / 1 kb DNA ladders / Extended-range 1 kb ladders / Ladders requiring loading dye
Classification is based on the supplied product name. Confirm formulation, application and compatibility in the manufacturer documentation.
DNA ladders / 1 kb DNA ladders / Extended-range 1 kb ladders / Ladders requiring loading dye
Candidate only. Verify activity, specificity, formulation and protocol compatibility before substitution. Extended-range DNA sizing ladder, 100 bp to 12 kb; bands differ from other 1 kb Plus ladders.
DNA ladders / 1 kb DNA ladders / Extended-range 1 kb ladders / Ready-to-load ladders optimized for precast safe stains
Classification is based on the supplied product name. Confirm formulation, application and compatibility in the manufacturer documentation.
DNA ladders / 1 kb DNA ladders / Extended-range 1 kb ladders / Ladders requiring loading dye
Manufacturer lists a fragment range of 75 to 20,000 bp. Check the individual band pattern and gel conditions; nominal ladder increments alone do not establish interchangeability.

Final groups are designed around experimental substitution requirements. Group membership is provisional until the necessary technical details have been verified for the intended experiment.
Start with your application, then verify the technical requirements against each manufacturer’s documentation.
