Purity: ≥98%
Naspm 3HCl (1-Naphthylacetyl spermine trihydrochloride), the trihydrochloride salt of Naspm, is a synthetic analog of Joro spider toxin and a calcium permeable AMPA (CP-AMPA) receptors antagonist.
| ln Vitro |
The Ca2+-permeable and inward rectifying AMPA receptors expressed in type II neurons are specifically inhibited by NASPM. On type I neurons' AMPA receptors, it has no impact. With an IC50 value of 0.33 µM, NASPM inhibits AMPA receptors in type II neurons at -60 mV. Applications and voltages affect how well NASPM blocks Ca2+ permeable AMPA receptors [1].

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.
Calculation results
Working concentration： mg/mL；
Method for preparing DMSO stock solution： mg drug pre-dissolved in μL DMSO (stock solution concentration mg/mL). Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug.
Method for preparing in vivo formulation:：Take μL DMSO stock solution, next add μL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O，mix and clarify.
(1) Please be sure that the solution is clear before the addition of next solvent. Dissolution methods like vortex, ultrasound or warming and heat may be used to aid dissolving.
(2) Be sure to add the solvent(s) in order.
