GenScript provides a wide selection of DNA ladders ranging from 100 bp to 23 kb that accurately separate bands and estimate the size and quantity of DNA. A variety of these markers are also available in the ready–to-use form. There is no need to heat, mix, or dilute these markers prior to loading them on your gel. The key to accurate band analysis is to use the correct markers for your particular application. The following table can help you choose the one you need.
DNA ladders are nucleic acid fragments of specific base pair length designed for sizing linear double-stranded or single-stranded DNA fragments. The 100 bp DNA ladder provides accurate sizing of nucleic acid small fragments from 100 to 1,500 bp. By using the 1 KB DNA Ladder, you can size fragments ranging from 100 bp to 10 kb. The bands appear crisp and clear, making it easy to identify the proper size of your fragments
Ready-to-UseTM DNA ladders minimize the time spent in thawing, diluting, and adding sample buffer to your DNA ladders. Simply transfer your ready-to-use DNA ladder from the vial to the gel. These ladders are stable at room temperature.
