TARGETMOL CHEMICALS INC Sphingosine-1-phosphate 1MG
Sphingosine-1-phosphate (S1P) is an agonist for S1P1-5 receptors and a ligand for GPR3, GPR6, and GPR12. As an intracellular second messenger, it mobilizes Ca2+ and acts as an extracellular ligand for G-protein coupled receptors. This important lipid mediator is generated from sphingosine or other membrane phospholipids. Purity 98.66%
TARGETMOL CHEMICALS INC Nortriptyline hydrochloride
Also available in 1 mL, 25 mg, 50 mg, 100 mg, 200 mg and bulk. Please contact Fisher for quotes. Nortriptyline hydrochloride (ELF-101 hydrochloride) is a metabolite of AMITRIPTYLINE that is also used as an antidepressive agent. Nortriptyline is used in major depression, dysthymia, and atypical depressions. Purity 99.71%
