Mechanism of Action
The mechanism of action for RNAimax transfection reagent is a multi-step process that highlights its effectiveness. When RNAimax is mixed with RNA, it forms lipid-nucleic acid complexes known as lipoplexes. These complexes are then introduced to the target cells. The positive charge of cationic lipids facilitates endocytosis, a process where cells engulf external molecules from their environment.
Once inside the cell, these lipoplexes are transported to the endosomes. In ideal circumstances, the lipid formulation triggers a pH change within the endosomes, promoting a fusion between the lipid components and the endosomal membrane. This pH-dependent fusion is crucial as it liberates the RNA into the cytoplasm, where it can subsequently participate in protein synthesis or other cellular processes.
It’s important to note that the efficacy of the RNAimax reagent in gene delivery is influenced by various factors, including:
- Cell Type: Different cells may internalize the complex better or worse.
