PD-L2 is a type I membrane protein and structurally consists of an extracellular region containing one V-like and one C-like Ig domain; a transmembrane region; and a short cytoplasmic domain. PD-L2 is expressed on antigen presenting cells; placental endothelium and medullary thymic epithelial cells; and can be induced by LPS in B cells; INF-\u0026amp; gamma; in monocytes; or LPS plus IFN-\u0026amp; gamma; in dendritic cells. The CD28 and B7 protein families are critical regulators of immune responses. PD-L2 and PD-L1 are two ligands for PD-1; member of the CD28\/CTLA4 family expressed on activated lymphoid cells; and thus provide signals for regulating T cell activation and immune tolerance. The interaction of B7-DC\/PD-1 exhibited a 2-6-fold higher affinity compared with the interaction of B7-H1\/PD-1.\n\nActivity: Immobilized recombinant human PD-L2 at 1 μg\/ml (100 μl\/well) can bind recombinant human PD1 with a linear range of 7.8-1000 ng\/ml.\n\nSequence: Met 1-Pro 219\n\nPurity: \u0026gt; 98 % as determined by reducing SDS-PAGE.\n\nFormulation: Lyophilized from sterile PBS, pH 7.4\nNormally 5 % - 8 % trehalose, mannitol and 0.01% Tween80 are added as protectants before lyophilization.\nPlease refer to the specific buffer information in the printed manual.\n\nReconstitution: Please refer to the printed manual for detailed information.\n\nEndotoxin: \u0026lt; 1.0 EU per μg of the protein as determined by the LAL method.\n\nCalculated MW: 24 kDa\n\nObserved MW: 40-45 kDa\n\nStorage: Generally, lyophilized proteins are stable for up to 12 months when stored at -20 to -80℃. Reconstituted protein solution can be stored at 4-8℃ for 2-7 days. Aliquots of reconstituted samples are stable at \u0026lt; -20℃ for 3 months.\n\nShipping: This product is provided as lyophilized powder which is shipped with ice packs.\n\nResearch Use Only","brand":"Elabscience","offers":[{"title":"Default Title","offer_id":43104323174579,"sku":"PKSH031704-100","price":680.4,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0305\/9482\/6376\/products\/logo_new_2320a96b-a176-4dd6-97a9-716a96c7a466.png?v=1709294289","url":"https:\/\/afsbio.com\/products\/recombinant-human-b7-dc-pd-l2-cd273-protein-his-tagactive-pksh031704","provider":"AFSBio Inc.","version":"1.0","type":"link"}
