Accugent has significant experience in developing simple formulations that are suitable for parenteral, subcutaneous or ophthalmic dosing. We can optimize formulation parameters while maintaining chemical stability of the drug. We have experience in developing formulations for antisense oligonucleotides, DNA duplexes, siRNA and aptamers. We also have the analytical tools necessary to evaluate the manufacturability, performance and stability of these formulations.

We offer the following services:

Preformulation studies

• Solubility in various media
• Solubility/stability as a function of pH
• pK_a determination
• Osmolality
• T_m studies of oligonucleotides
