Product Description
Confirming the size of microRNAs on a gel is much easier with a ladder designed for that range. This Zymo Research size marker provides single-stranded RNA references for polyacrylamide gel separations, helping you approximate the length of miRNAs and other small RNA species with confidence.
This listing is for catalog number R1090: ZR small-RNA Ladder, 10 µg. The ladder contains four single-stranded RNA oligonucleotides of 17, 21, 25 and 29 bases, bracketing the typical size of mature microRNAs. It is supplied in water and can be visualized with stains suited to single-stranded nucleic acids, such as GelStar. Load it alongside your samples on a PAGE gel. Supplied as 10 µg. Order it from LIGHT LABS and keep your workflow moving.
Key Features
- miRNA size range – Four bands at 17, 21, 25 and 29 nt.
- Single-stranded RNA – Migrates like small RNA samples for accurate comparison.
- PAGE optimized – Designed for polyacrylamide gel separation.
- Stain compatible – Visualize with single-strand nucleic acid stains such as GelStar.
- Supplied in water – Simple to dilute and load.
