We offers a broad selection of DNA ladders/markers ranging from 10 bp to 48.5 kb, for accurate analysis of linear double-stranded DNA in agarose or polyacrylamide gels. Most DNA ladders/markers are available both in a convenient ready-to-use format (premixed with loading dye solution) and in the conventional format (dissolved in storage (TE) buffer). Our DNA ladders/markers are manufactured and quality controlled to supersede all industry standards, making our the quality leader for DNA standards.
DNA ladders are made of chromatography-purified individual DNA fragments using a proprietary patent-pending technology for preparation of pharmaceutical grade plasmid DNA.
are used for the production of DNA fragments for our ladders/markers. As a result, these products are stable during prolonged incubations at room temperature and multiple freeze-thaw cycles.

we are Biotechnology manufacture with advanced equipment, consist of many biological technology specialized person, enzyme engineering technology is our core .we specialized in various kinds of dNTP (mix), dATP, dCTP, dGTP dTTP,ATP,CTP,GTP,UTP and so on for many years .All items r meet high technique standards at comparative price .we have many fixed abroad customers. Except dNTP and NTP we also produce DNA Polymerase (Taq、pfu、 M-MLV) and DNA molecular markers ,and other molecular Biology reagent. All the products passed the QC inspection strictly. We supply OEM and Bulk service for all products and keep secret strictly, hope we can establish steady and long-term business cooperation between us.
