Extend RNA Size Analysis Up to 15 kb
An ultra-high-range RNA size standard with 6, 9, 12 and 15 kb reference bands for electrophoretic analysis of very long IVT RNA and self-amplifying RNA (saRNA) constructs.
Four High-Molecular-Weight RNA Reference Bands
CR00042 focuses specifically on the upper RNA size range, providing reference points for long RNA constructs that extend beyond the range of conventional RNA markers.
When a 12K Ladder Is Not Enough
Long IVT RNA and saRNA constructs can reach sizes where conventional RNA ladders — and even high-range ladders ending at 12 kb — no longer provide an upper reference band.
High Range RNA Ladder
A broader reference ladder for RNA ranging from hundreds of nucleotides through 12 kb.
Ultra High Range RNA Ladder
Concentrates reference bands in the 6–15 kb range for very long RNA constructs.
Designed for Very Long RNA Research
High-molecular-weight IVT RNA size comparison.
Reference bands suitable for long self-amplifying RNA constructs.
High-range reference for agarose gel-based RNA analysis.
