Micro Cell Vesicles as A Transfection Tools
Transfection of certain cell types including stem cells and primary cells such as adipocytes often face issues of low transfection efficiency or high toxicity.
Micro Cell vesicles (mCVTs) are able to transfect these cell types with improved transfection efficacy and reduced toxicity.

mCVTs, are a proprietary non-viral Drug Delivery System capable of delivering plasmids, siRNAs or small molecules with low toxicity.
In addition, these microparticles can be further amended to demonstrate targeting to certain cell types both in vitro & in vivo.
