KYL peptide
Based on 3 publication(s) in Google Scholar
KYL peptide, an antagonistic peptide, selectively targets EphA4 receptor (IC50:4.22 μM, Kd:1.3 μM). KYL peptide binds to the ligand-binding domain of EphA4, effectively alleviates Aβ-induced synaptic dysfunction and synaptic plasticity defects in AD mice. KYL peptide can promote nerve regeneration after injury and modulating immune responses.

H2O : ≥ 55 mg/mL (37.52 mM)
* "≥" means soluble, but saturation unknown.
Please refer to the solubility information to select the appropriate solvent. Once prepared, please aliquot and store the solution to prevent product inactivation from repeated freeze-thaw cycles.
Storage method and period of stock solution: -80°C, 6 months; -20°C, 1 month (sealed storage, away from moisture and light, under nitrogen). When stored at -80°C, please use it within 6 months. When stored at -20°C, please use it within 1 month.
* Note: If you choose water as the stock solution, please dilute it to the working solution, then filter and sterilize it with a 0.22 μm filter before use.
