CD34 protein is selectively expressed on hematopoietic progenitor cells and the small vessel endothelium of a variety of tissues. It has been widely used as a stem and progenitor cell marker, and clinical CD34+ stem cell transplantation (CD34+SCT) has been performed for tumor purging. CD34 monoclonal antibodies are widely used to identify and isolate hemopoietic progenitors and to classify acute and chronic leukemias.\n\nActivity: Measured by the ability of the immobilized protein to support the adhesion of the HUVEC human umbilical vein endothelial cell line. When 4 x 10\u003csup\u003e4\u003c\/sup\u003e cells\/well are added to mouse CD34 coated plates (0.8 μg\/ml, 100 μl\/well), approximately \u0026gt; 30 % will adhere after one hour at 37 ℃.\n\nSequence: Met 1-Thr 287\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: 28.6 kDa\n\nObserved MW: 50-60 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":43104263667891,"sku":"PKSM040592-50","price":1024.8,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0305\/9482\/6376\/products\/logo_new_6bc53ae9-36e5-44c9-b5e5-27477b0fcba0.png?v=1709293359","url":"https:\/\/afsbio.com\/products\/recombinant-mouse-cd34-protein-his-tagactive-pksm040592","provider":"AFSBio Inc.","version":"1.0","type":"link"}
