pep2-SVKI
Based on 1 Customer Validation
pep2-SVKI is a selective peptide inhibitor. pep2-SVKI inhibits the binding of AMPA-type glutamate receptor (GluA2) (C-terminal PDZ site) to glutamate receptor interacting protein (GRIP), AMPA receptor binding protein (ABP), and C-kinase interacting protein (PICK1). pep2-SVKI increases the amplitude of AMPA receptor-mediated currents and blocks long-term depression (LTD). pep2-SVKI can be used to study neurological diseases.

Biological Activity
pep2-SVKI (1 mM) reduces (Miniature Excitatory Postsynaptic Current) mEPSC amplitude at both −60 mV and +40 mV in the synaptic membrane of stellate cells[1].
pep2-SVKI (100 μM) causes an increase in AMPAR-mediated (Excitatory Postsynaptic Current) EPSCs in hippocampal CA1 Neurons[2].
pep2-SVKI (100 μM) prevents the expression of LTD in a (Protein Kinase C) PKC-Dependent Manner in hippocampal CA1 Neurons[2].
pep2-SVKI increases tritium release induced by exposure to 100 μM AMPA in hippocampal synaptosomes prelabeled with (radiolabeled norepinephrine) [3H]NA and potentiates the AMPA-evoked release of [3H]NA in rat hippocampal synaptosomes[3].
pep2-SVKI causes increase in the number of AMPARs exposed on the membrane in rat hippocampal synaptosomes[3].
pep2-SVKI abolishes the sensitivity to Cyclothiazide (HY-101165) of the AMPA receptors controlling [3H]NA release[3].

Select the appropriate dissolution method based on your experimental animal and administration route.
- For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
- To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
- The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.
Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline
Solubility: 2.5 mg/mL (1.95 mM); Clear solution; Need ultrasonic
This protocol yields a clear solution of 2.5 mg/mL.
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.
Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.
Add each solvent one by one: 10% DMSO 90% (20% SBE-β-CD in Saline)
Solubility: 2.5 mg/mL (1.95 mM); Suspended solution; Need ultrasonic
This protocol yields a suspended solution of 2.5 mg/mL. Suspended solution can be used for oral and intraperitoneal injection.
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly.
Preparation of 20% SBE-β-CD in Saline (4°C, storage for one week): 2 g SBE-β-CD powder is dissolved in 10 mL Saline, completely dissolve until clear.
