RNA Ladders (Mid/High/Ultra High Range) & Custom RNA Ladder Service

Croyez Bioscience (Taiwan) offers a dedicated RNA ladder product line, purpose-built for accurate sizing of RNA and mRNA on gels — something a standard DNA ladder cannot reliably do, since RNA and DNA fragments of the same length migrate differently. Our range includes:

RNA Ladder

Mid Range RNA Ladder

High Range RNA Ladder

Ultra High Range RNA Ladder

These ladders give mRNA manufacturers, CDMOs, and QC/analytical labs a reliable size reference across the full range of transcript lengths seen in IVT mRNA production, from short reporter constructs to large, capped, poly-A tailed mRNAs.

For customers with non-standard sizing needs, we also offer a Custom RNA Ladder Service to produce ladders tailored to a specific size range or application.

We are seeking distribution and channel partners in Europe who serve mRNA developers, CDMOs, and molecular biology labs that need accurate, RNA-specific sizing standards for their gel electrophoresis and QC workflows.
