|Description||L-NAME HCl (NG-Nitroarginine methyl ester, N-Nitro-L-arginine methylester) is a nonselective inhibitor of nitric oxide synthetases (NOS) for nNOS (bovine), eNOS (human), and iNOS (murine), with Ki of 15 nM, 39 nM and 4.4 μM, respectively.|
NG-nitro-L-arginine methyl ester (L-NAME; at 0.1-100 mM) causes concentration-dependent inhibition of the Ca2(+)-dependent endothelial NO synthase from porcine aortae. L-NAME causes an endothelium-dependent contraction and an inhibition of the endothelium-dependent relaxation induced by acetylcholine (ACh) in aortic rings.  In another research, Viability of rMC-1 cells or BREC in 25 mM glucose is significantly less than at 5 mM glucose, and this cell death is inhibited by l-NAME in both cell types. 
|In vivo||L-NAME (0.03-300 mg kg-1, i.v.) induces a dose-dependent increase in mean systemic arterial blood pressure accompanied by bradycardia. L-NAME (100 mg kg-1, i.v.) inhibits significantly the hypotensive responses to ACh and bradykinin. The increase in blood pressure and bradycardia produced by L-NAME is reversed by L-arginine (30-100 mg kg-1, i.v.) in a dose-dependent manner. |
Enzyme Assay:The oxidation of L-arginine is monitored by the conversion of [3H]- or [14C]-arginine to L-citrulline which separates L-citrulline from L-arginine by Dowex 50x8-200 (Na) chromatography. Typical reaction mixtures (100 pL) contains 50 mM HEPES, pH 7.0, 8 pM tetrahydrobiopterin, 1 mM CaC12, 0.01 mg/mL calmodulin, 0.5 mM EDTA, 0.450 pM [14C]-arginine (30000 cpm), and 100-200 pM NADPH. The cNOS-catalyzed oxidation of NADPH to NADP+ is monitored by the reduction of absorbance at 340 nm with a Kontron 860 spectrophotometer in a volume of 300 pL. All reactions are at 30 ℃ unless otherwise indicated.

|In vivo||Add solvents to the product individually and in order(Data is from Selleck tests instead of citations):
For best results, use promptly after mixing.
* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.

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)
*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).
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 )
* 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.
