Spadin was identified as an endogenous antagonist of TREK-1 (TWIK-related K+ channel 1, encoded by KCNK2), a two-pore domain background potassium channel with high expression in hippocampal and cortical neurons.\u003c\/p\u003e\n\u003cp\u003eTREK-1 is a mechanosensitive, temperature-sensitive, and lipid-regulated channel that normally acts to stabilize neuronal resting membrane potential. Its blockade by PE-22-28 produces rapid (24–48 hour onset) antidepressant-like effects in preclinical models — a pharmacological profile distinct from classical antidepressants that require weeks of administration. Research also indicates TRPV4 modulatory activity, adding to its mechanistic complexity.\u003c\/p\u003e\u003ch2\u003eResearch Applications\u003c\/h2\u003e\u003cp\u003ePE-22-28 has been examined in experimental studies related to:\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eTREK-1 (KCNK2) potassium channel antagonism and neurophysiology\u003c\/li\u003e\n\u003cli\u003eRapid-onset antidepressant mechanism research (24–48h)\u003c\/li\u003e\n\u003cli\u003eSpadin peptide analog pharmacology and structure-activity studies\u003c\/li\u003e\n\u003cli\u003eTRPV4 modulation and mechanosensitive channel research\u003c\/li\u003e\n\u003cli\u003eDepression and mood disorder preclinical models\u003c\/li\u003e\n\u003cli\u003eComparison with classical antidepressants on onset kinetics\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eHandling and Storage (Laboratory Guidance)\u003c\/h2\u003e\n\u003cp\u003eThis product is supplied as a lyophilized peptide powder.\u003c\/p\u003e\n\u003cp\u003eTypical laboratory handling recommendations include:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eStore at 2–8 °C upon receipt.\u003c\/li\u003e\n\u003cli\u003eProtect from heat, moisture, and direct light.\u003c\/li\u003e\n\u003cli\u003eAvoid excessive agitation of the solution to maintain peptide stability.\u003c\/li\u003e\n\u003cli\u003eReconstitution, if required for laboratory experiments, should be performed using appropriate sterile laboratory techniques.\u003c\/li\u003e\n\u003cli\u003eUse of acetic acid water (0.6%) or sterile bacteriostatic water is recommended for peptides with low aqueous solubility.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eFor reconstitution, \u003ca href=\"https:\/\/mvlabs.mx\/pages\/calculadora-de-peptidos\" target=\"_blank\"\u003eCLICK HERE to use the PEPTIDE CALCULATOR\u003c\/a\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eLaboratory protocols may vary depending on the specific research application.\u003c\/p\u003e\u003ch2\u003eQuality Information\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eResearch grade material\u003c\/li\u003e\n\u003cli\u003eHigh purity (≥99%)\u003c\/li\u003e\n\u003cli\u003eLyophilized for stability\u003c\/li\u003e\n\u003cli\u003eIntended for controlled laboratory environments\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eDocumentation such as analytical data or certificates of analysis may be available depending on the supplier.\u003c\/p\u003e\u003ch2\u003eImportant Disclaimer – Research Use Only\u003c\/h2\u003e\n\u003cp\u003eThis product is provided strictly for laboratory research and analytical purposes.\u003c\/p\u003e\n\u003cp\u003eIt is not intended for human or animal consumption.\u003c\/p\u003e\n\u003cp\u003eThis compound: is not a drug, is not a dietary supplement, and has not been approved by regulatory authorities such as the FDA, EMA, or other agencies for medical use.\u003c\/p\u003e\n\u003cp\u003eThe purchaser agrees that the product will be handled only by qualified professionals in appropriate research facilities and in accordance with all applicable laws and regulations.
