Human Lipocalin-1 \/ VEGP was originally  described as a major protein of human tear fluid, which was thought to be tear  specific. Lipocalin-1 \/ VEGP is identical with lingual von Ebner's gland  protein, and is also produced in prostate, nasal mucosa and tracheal mucosa.  Homologous proteins have been found in rat, pig and probably dog and horse.  Lipocalin-1 \/ VEGP is an unusual lipocalin member, because of its high  promiscuity for relative insoluble lipids and binding characteristics that  differ from other members. Lipocalin-1 \/ VEGP acts as the principal lipid  binding protein in tear fluid, a more general physiological function has to be  proposed due to its wide distribution and properties. Lipocalin-1 \/ VEGP would  be ideally suited for scavenging of lipophilic, potentially harmful substances  and thus might act as a general protection factor of epithelia. Lipocalin-1 \/  LCN1 could play a role in taste reception. It could be necessary for the  concentration and delivery of sapid molecules in the gustatory system.  Lipocalin-1 \/ LCN1 can bind various ligands, with chemical structures ranging  from lipids and retinoids to the macrocyclic antibiotic rifampicin and even to  microbial siderophores. It exhibits an extremely wide ligand pocket.\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-Asp176\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: 19.0 kDa\u003c\/p\u003e\u003cp\u003e\u003cb\u003eObservedMW\u003c\/b\u003e: 20 kDa\u003c\/p\u003e","brand":"GeneBio Systems","offers":[{"title":"Default Title","offer_id":47972995137636,"sku":"PKSH031078","price":155300.0,"currency_code":"JPY","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0558\/8588\/9636\/files\/no_image_default_image-jpeg_eee8e410-0279-4ed2-b493-83daac0ffa95.jpg?v=1772201721","url":"https:\/\/www.genebiosystems.com\/en-jp\/products\/recombinant-human-lcn1-vegp-lipocalin-1-protein-his-tag","provider":"GeneBio ","version":"1.0","type":"link"}
