Lidocaine (Standard) is the analytical standard of Lidocaine. This product is intended for research and analytical applications. Lidocaine (Lignocaine) inhibits sodium channels involving complex voltage and using dependence[1]. Lidocaine decreases growth, migration and invasion of gastric carcinoma cells via up-regulating miR-145 expression and further inactivation of MEK/ERK and NF-kappaB signaling pathways. Lidocaine is an amide derivative and has potential for the research of ventricular arrhythmia[2].
