Biological Activity

Description Lidocaine hydrochloride is a local anesthetic and cardiac depressant used as an antiarrhythmia agent.
In vitro

Lidocaine above 1.25 g/l reduces cellular viability and triggers apoptosis in HCE cells in a time- and dose-dependent manner. Lidocaine-induced apoptosis is caspase dependent and may be related to mitochondrial pathway[1]. Lidocaine, at the level of tissue concentration under topical or local administration, also has a direct inhibitory effect on the activity of epidermal growth factor receptor (EGFR), which is a potential target for antiproliferation in cancer cells[3].

In vivo Intravenous administration of the local anaesthetic lidocaine has been used to treat neuropathic pain for several decades and significantly improves postoperative pain associated with complex spine surgery and cholecystectomy. It is well established that lidocaine used for regional anaesthesia blocks impulses in peripheral nerves by inhibiting voltage-gated sodium (Na+) channels. Intravenous lidocaine has an analgesic effect on mechanical noxious response, decreases the spinal noxious response induced by peripheral pinch stimuli and the frequency of spontaneous excitatory postsynaptic currents(EPSCs) without changing their amplitude. It has no effect on spontaneous inhibitory postsynaptic currents and produces an outward current in SG neurons[2].


Cell Research:[1]
- Collapse
  • Cell lines: Human Corneal Endothelial Cells
  • Concentrations: 0.15625–10.0 g/l
  • Incubation Time: 4-28 hr
  • Method: Cells at logarithmic phase are treated with lidocaine hydrochloride at concentrations (w/v) from 10 to 0.15625 g/l in step dilutions. HCE cells without lidocaine treatment are used as controls. The morphology and growing status of the cells are monitored every 4 hr.

Bio Calculators

Molarity Calculator

Molarity Calculator

Calculate the mass, volume or concentration required for a solution. The Selleck molarity calculator is based on the following equation:

Mass (mg) = Concentration (mM) × Volume (mL) × Molecular Weight (g/mol)

  • Mass
    Molecular Weight

*When preparing stock solutions, please always use the batch-specific molecular weight of the product found on the via label and MSDS / COA (available on product pages).

Dilution Calculator

Dilution Calculator

Calculate the dilution required to prepare a stock solution. The Selleck dilution calculator is based on the following equation:

Concentration (start) x Volume (start) = Concentration (final) x Volume (final)

This equation is commonly abbreviated as: C1V1 = C2V2 ( Input Output )

  • C1

* When preparing stock solutions always use the batch-specific molecular weight of the product found on the vial label and MSDS / COA (available online).

Definitions of molecular mass, molecular weight, molar mass and molar weight:

Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12)
Molar mass (molar weight) is the mass of one mole of a substance and is expressed in g/mol.
