Application

Polyethylene glycols (PEGs) are FDA approved hydrophilic polymers. They are non-toxic, non-immunogenic and non-antigenic, and are widely used in a varity of biomedical applications such as bioconjugation, drug delivery, surface functionalization, and tissue engineering. Methoxy PEG Hydrazide reacts with aldehydes and ketones to give stable hydrazones in a single step; it can also react with activated carboxylic acids.

Recent Progress on Nonviral Delivery Carriers for CRISPR/Cas9 Systems

The CRISPR/Cas9 system has recently emerged as a highly specific, efficient, and versatile gene editing technology that can be utilized to build disease models and correct diseased genes. Safe and effective delivery vectors for the CRISPR/Cas9 system are in critical need to enable clinical development and future applications of CRISPR/Cas9 systems. Professor Yang Liu summarizes recent progress in nonviral nanoparticle approaches for CRISPR/Cas9 delivery.

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
