Ambion RNA Markers

Ambion RNA ladders and markers are available for sizing single-stranded RNA in glyoxal or formaldehyde agarose gels.The Ambion Millennium markers are evenly spaced, making them ideal for constructing accurate standard curves for mRNA size determination.

Ambion Millenium Markers

Get accurate size determination of single-stranded RNA between 0.5 and 9 kb and also use in any northern blot protocol.

Ambion Century Markers

For isotopic and nonisotopic ribonuclease protection assays—when single-stranded RNA size standards are needed for denaturing gel electrophoresis.
