Programmed death-1 ligand-1 (PD-L1; CD274; B7-H1) has been identified as the ligand for the immunoinhibitory receptor programmed death-1(PD1\/PDCD1) and has been demonstrated to play a role in the regulation of immune responses and peripheral tolerance. By binding to PD1 on activated T-cells and B-cells; PD-L1 may inhibit ongoing T-cell responses by inducing apoptosis and arresting cell-cycle progression. Accordingly; it leads to growth of immunogenic tumor growth by increasing apoptosis of antigen specific T cells and may contribute to immune evasion by cancers. PD-L1 thus is regarded as promising therapeutic target for human autoimmune disease and malignant cancers.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eConcentration\u003c\/b\u003e: \u003c\/p\u003e\u003cp\u003e\u003cb\u003eActivity\u003c\/b\u003e: Immobilized Anti-Human PDL1 mAb at 2μg\/ml (100 μl\/well)can bind Human PD-L1-His.The ED50 of Human PD-L1-6His is 5.57 ng\/ml.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eSequence\u003c\/b\u003e: Phe19-Thr239\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: Lyophilized from a 0.2 μm filtered solution of 20mM PB, 4% Mannitol, 0.02% Tween 80, pH7.4.\u003cbr\u003eNormally 5% - 8% trehalose, mannitol and 0.01% Tween 80 are added as protectants before lyophilization.\u003cbr\u003ePlease refer to the specific buffer information in the printed manual.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eReconstitution\u003c\/b\u003e: Please refer to the printed manual for detailed information.\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: 26.3 kDa\u003c\/p\u003e\u003cp\u003e\u003cb\u003eObservedMW\u003c\/b\u003e: 34-42 kDa\u003c\/p\u003e","brand":"GeneBio Systems","offers":[{"title":"Default Title","offer_id":47982505230436,"sku":"PKSH033557","price":29300.0,"currency_code":"JPY","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0558\/8588\/9636\/files\/no_image_default_image-jpeg_54fb9ce4-0406-4a50-9ea3-a68d32b7738d.jpg?v=1772388645","url":"https:\/\/www.genebiosystems.com\/en-jp\/products\/recombinant-human-pd-l1-b7-h1-cd274-protein-his-tag","provider":"GeneBio ","version":"1.0","type":"link"}
