- Broad size range - 5 evenly distributed bands from 50 bp to 2000 bp
- Ready-to-use - reduces handling steps and saves time
- Fast separation - ideal for PCR products
- Supplied with loading dye - for loading sample DNA
Agarose gels are often run to check and see if a band is present or not, for example in a PCR reaction. With 5 regularly spaced bands, ranging from 100 bp to 2000 bp, EasyLadder™ I is a molecular weight marker especially designed for fast size determination of linear double-stranded DNA fragments on 0.5% to 3% TAE or TBE agarose gels.
This ready-to-use format, with a red loading dye already added to the ladder, reduces handling steps and saves time; simply transfer EasyLadder I from the vial to the gel, along with the PCR product and run at high voltage for just a few minutes (1-3 cm of a gel lane). The concentration of DNA in each of the EasyLadder I bands is provided for optionally determining the approximate mass of DNA in comparably intense sample bands of similar size. The EasyLadder I is also supplied with a 5x loading dye for the loading of sample DNA.
- Determination of PCR amplicon size
- Confirmation of plasmid construction
- Restriction fragment size determination

Storage & Stability
All components should be stored at -20°C upon receipt for optimum stability. Repeated freeze/thaw cycles should be avoided. When stored under the recommended conditions and handled correctly, full activity of the reagents is retained until the expiry date on the outer box label.
Components may also be stored at +4°C or room temperature if required, although storage at -20°C is always recommended.
When stored at +4°C, EasyLadder I can be stored for up to 12 months. When stored at room temperature, EasyLadder I can be stored for up to 1 month
All HyperLadders and EasyLadders are ready-to-load and require no addition of loading buffer prior to use. In general, the smaller the DNA product, the higher the percentage of Agarose required in the gel. As a guide for optimization we would suggest to use the EasyLadder I with 2% (w/v) agarose gel,
Hyperladder 100bp with 2% (w/v) agarose gel,
Hyperladder 1kb with 1% (w/v) agarose gel,
Hyperladder 50bp with 1.5% (w/v) agarose gel and
Hyperladder 25bp with 3.5% (w/v) agarose gel.
Please have a look into the related application note for more information about ladder migration in different gel concentrations.
Problems with our HyperLadder and EasyLadder are extremely rare, so please make sure you have carried out each of the following correctly:
- Used the correct percentage of agarose in your gel for the specific marker in question.
- Used 5 µL of the marker per lane.
- Used the correct concentration of stain (e.g. EtBr) to visualise correctly.
- Vortexed the marker gently before use.
Should problems persist, please contact technical services for further assistance.
No, our Ladder range is supplied in a ready-to-load format to be directly loaded onto your agarose gel. An additional vial of 5x Loading Buffer is supplied with each of our markers for use with your samples.
Other stains, such as SYBR® Green Gel Stain, can be used with our ladders as effectively as EtBr. The fluorescence of the gel as a whole may vary depending on the stain used, however the relative intensities of the marker bands and of the samples run will remain the same, thus the HyperLadder / EasyLadder remains quantitative.
