dsDNA 50 to 1350 Ladder, 1/pk

The dsDNA 50 to 1350 Ladder is a lyophilized mix of 17 proprietary double-stranded DNA fragments, spanning a size range from 50 to 1350 base pairs (bp). Featuring high-abundance bands at 1350, 500, and 200 bp, it serves as an effective reference tool for LC-UV analysis in both SEC and IEX workflows. These distinct bands aid in reliable size calibration and system performance validation across analytical assays.

This ladder is intended for use as a resolution and system suitability check for oligonucleotide, gene therapy, and cell therapy applications. With a solid formulation and long shelf life of 24 months (1 week post-reconstitution), it is designed to perform under ambient shipping and frozen storage conditions (-20°C). It is compatible with LC systems, including UPLC, UHPLC, and HPLC instruments, and integrates seamlessly into GMP-regulated workflows thanks to Waters' ISO-certified manufacturing standards.
