The lyophilized product may be difficult to visualize. Add solvent directly to the centrifuged vial. Tap the vial to aid in dissolving the lyophilized product. Tilt and gently roll the liquid over the walls of the vial. Avoid vigorous vortexing. Light vortexing for up to 3 seconds is acceptable if needed. The product is soluble in pure water at high micromolar concentrations (100 µM - 1 mM). For long-term storage in solution, we recommend preparing a stock solution by dissolving the product in double-distilled water (ddH2O) at a concentration between 100-1000x of the final working concentration. Divide the stock solution into small aliquots and store at -20°C. Before use, thaw the relevant vial(s) and dilute to the desired working concentration in your working buffer. Centrifuge all product preparations before use. It is recommended to prepare fresh solutions in working buffers just before use. Avoid multiple freeze-thaw cycles to maintain biological activity\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShipping:\u003c\/strong\u003e Shipped at room temperature. Product as supplied can be stored intact at room temperature for several weeks.

They are broadly classified into three subtypes: SK, IK and BK channels (small, intermediate and big conductance, respectively). The three small-conductance Ca2+-activated K+ channels KCa2.1 (SK1), KCa2.2 (SK2), and KCa2.3 (SK3)1, and the intermediate-conductance KCa3.1 channel (IK1, SK4) play important roles in various physiological functions by modulating Ca2+-signaling cascades and regulating membrane potential, in the CNS and also peripherally1-2.Outside of the nervous system KCa2 channels, especially KCa2.3, are involved in blood pressure regulation3, contractility of urinary bladder smooth muscle and metabolism4. Like KCa2.3, KCa3.1 is further expressed in vascular endothelium and contributes to blood pressure control by initiating the so-called endothelium derived hyperpolarizing factor (EDHF) response, a nitric oxide and prostacyclin independent component of endothelium-dependent relaxation5-9.SKA-31 is an activator of KCa3.1 and KCa2 channels (EC50 values are 260, 2900, 2900, 1900 nM for KCa3.1, KCa2.1, KCa2.3 and KCa2.2 respectively)10. It potentiates acetylcholine-induced EDHF-type dilations of mouse carotid arteries and lowers blood pressure in normotensive and hypertensive mice, by 4-6 and 12 mmHg, respectively10-11.SKA-31 was found to block TRPM7 channels, demonstrating an overlap between pharmacological compounds acting on TRP and KCa channels12.\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eLead time:\u003c\/strong\u003e 1-2 Business Days\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eCountry of origin:\u003c\/strong\u003e Israel\/IL\u003c\/p\u003e \u003ch3\u003eApplications key\u003c\/h3\u003e \u003cp\u003eApplication key: FC- Flow cytometry, IFC- Indirect flow cytometry, IHC- Immunohistochemistry,LCI- Live cell imaging, Calcium imaging assay,Cell survival assay, Electrophysiology, Neurite outgrowth assay.\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eBioassay tested:\u003c\/strong\u003e Yes\u003c\/p\u003e","brand":"Alomone Labs","offers":[{"title":"10 mg \/ 1","offer_id":53249713766765,"sku":"S-120-10MG-1","price":91.0,"currency_code":"USD","in_stock":true},{"title":"25 mg \/ 1","offer_id":53311575589229,"sku":"S-120-25MG-1","price":167.0,"currency_code":"USD","in_stock":true},{"title":"5 mg \/ 1","offer_id":53311575621997,"sku":"S-120-5MG-1","price":75.0,"currency_code":"USD","in_stock":true},{"title":"50 mg \/ 1","offer_id":53311575654765,"sku":"S-120-50MG-1","price":261.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7424\/7277\/files\/S-120_gr.gif?v=1778544449","url":"https:\/\/www.ebiohippo.com\/products\/ska-31-bhb21300317","provider":"BioHippo","version":"1.0","type":"link"}
