It is a 261 aa. protein which belongs to the peptidase S1 family and Kallikrein subfamily. This protein has 5 isforms produced by alternative splicing. It is a secreted protein and can forms a heterodimer with SERPINA5 which can inhibit its activity. KLK3 is also strongly inhibited by Zn2+; 100 times more abundant in semen than in serum. This inhibition is relieved by exposure to semenogelins; which are avid zinc binders. KLK3 can hydrolyzes semenogelin-1 thus leading to the liquefaction of the seminal coagulum.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eConcentration\u003c\/b\u003e: \u003c\/p\u003e\u003cp\u003e\u003cb\u003eActivity\u003c\/b\u003e: Not validated for activity\u003c\/p\u003e\u003cp\u003e\u003cb\u003eSequence\u003c\/b\u003e: Ile25-Pro261\u003c\/p\u003e\u003cp\u003e\u003cb\u003ePurity\u003c\/b\u003e:  \u0026gt; 95 % as determined by reducing SDS-PAGE.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eFormulation\u003c\/b\u003e: Supplied as a 0.2 μm filtered solution of 50mM Tris-HCl, 10mM CaCl\u003csub\u003e2\u003c\/sub\u003e, 150mM NaCl, 0.05% Brij 35, pH 7.5.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eReconstitution\u003c\/b\u003e: Not Applicable\u003c\/p\u003e\u003cp\u003e\u003cb\u003eEndotoxin\u003c\/b\u003e:  \u0026lt; 1.0 EU per μg of the protein as determined by the LAL method.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eCalculated MW\u003c\/b\u003e: 27.1 kDa\u003c\/p\u003e\u003cp\u003e\u003cb\u003eObservedMW\u003c\/b\u003e: 35 kDa\u003c\/p\u003e","brand":"GeneBio Systems","offers":[{"title":"Default Title","offer_id":47982472593508,"sku":"PKSH032949","price":82000.0,"currency_code":"JPY","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0558\/8588\/9636\/files\/no_image_default_image-jpeg_394a1d7c-1221-492f-8173-a009ed2eef66.jpg?v=1772385849","url":"https:\/\/www.genebiosystems.com\/en-jp\/products\/recombinant-human-psa-klk3-protein-aa-25-261-his-tag","provider":"GeneBio ","version":"1.0","type":"link"}
