Phosphoramidites are building blocks for synthesis of oligonucleotides,
which are used as gene therapeutics and diagnostic reagents.
Samchully’s high-quality phosphoramidites are produced and
supplied to the customers at competitive price based on the
bulk-scale production of raw materials, i.e. nucleosides.
We provide various type of packaging to meet different customer’s
needs and diverse model of synthesis. All products are controlled
under our strict QC and GMP system and credibly supplied to
the customers.
And Samchully is taking credit on its technology through the
supply of modified DNA/RNA phosphoramidites to the key oligonucleotide
companies. |
