GPA33 contains oneIg-like C2-type  (immunoglobulin-like) domain and oneIg-like V-type (immunoglobulin-like)  domain. The open reading frame encodes a 319-amino acid polypeptide having a  putative secretory signal sequence and 3 potential glycosylation sites. The  predicted mature protein has a 213-amino acid extracellular region, a single  transmembrane domain, and a 62-amino acid intracellular tail. Intracellular  traffic and recycling to the cell surface appear to play a major role in GPA33  function and to have an influence on its surface density superseding translational  regulation. GPA33 has become a promising target of immunologic therapy  strategies, but its biologic function and potential role in tumorigenesis are  unknown. EpCAM protein and GPA33 mRNA expressions are specific and sensitive  markers of Barrett's metaplasia (BM). GPA33 may also play a role in cell-cell  recognition and signaling.\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: Met 1-Ile 235\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 sterile PBS, pH 7.4\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: 25.4 kDa\u003c\/p\u003e\u003cp\u003e\u003cb\u003eObservedMW\u003c\/b\u003e: 35-40 kDa\u003c\/p\u003e","brand":"GeneBio Systems","offers":[{"title":"Default Title","offer_id":47986038046820,"sku":"PKSM040615","price":596.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0558\/8588\/9636\/files\/no_image_default_image-jpeg_47406bf9-8991-4eb1-beb4-b4cffa607654.jpg?v=1772480664","url":"https:\/\/www.genebiosystems.com\/en-us\/products\/recombinant-mouse-gpa33-glycoprotein-a33-protein-his-tag","provider":"GeneBio ","version":"1.0","type":"link"}
