50bp DNA Ladder
A 50bp DNA Ladder is a molecular biology reagent used as a size standard in agarose gel electrophoresis to estimate the size of DNA fragments. It consists of a mixture of double-stranded DNA fragments ranging from 50 to 500 base pairs in 50bp increments. Stored at -15 to -20 °C, it is stable for long-term use. Molekula supplies 50bp DNA Ladder from research to bulk quantities with full documentation and ISO 9001:2015 traceability.

Specifications
| Property | Value |
|---|---|
| Appearance | Clear colourless solution |
| Identification | 1 µg of the ladder is analyzed by agarose gel electrophoresis in parallel with the same composition ladder from a previous bulk lot. 13 fragments are visible and correspond to those from the previous bulk lot. |
| Concentration | Spectrophotometrical measurement of absorption at 260 nm. 0.5 µg/µl±4%. |
| Deoxyribonucleases | Incubation of DNA Ladder at elevated temperature (37 °C) and analysis on agarose gel. No changes in bands intensity, no smearing is observed after incubation. |
