FAQs

1. What is the difference between a DNA ladder and a DNA marker?

The terms are often used interchangeably; however, a “ladder” typically refers to fragments at regular, defined increments (like 100bp steps), while “markers” can include restriction digests that cover broader, irregular ranges.

Yes, our DNA ladders are provided in a ready-to-use format, meaning they are pre-mixed with gel loading buffer and tracking dyes for immediate application to the gel.

For long-term stability, most DNA ladders should be stored at –20°C. They are stable for several months at 4°C for frequent use, but repeated freeze-thaw cycles should be avoided.

For fragments below 500bp, a Low Range DNA Marker (25bp–500bp) or a 50bp ladder is recommended to ensure high resolution between small bands.

A 1.0% to 1.5% agarose gel is typically ideal for resolving 1kb wide-range ladders (100bp to 10kb), providing the best balance of separation and band clarity.
