{"product_id":"nsj-claudin-18-antibody-cldn18-primary-antibody","title":"Claudin 18 Antibody \/ CLDN18","description":"\u003cp\u003eClaudin-18 is a protein that in humans is encoded by the CLDN18 gene. This gene encodes a member of the claudin family. Claudins are integral membrane proteins and components of tight junction strands. Tight junction strands serve as a physical barrier to prevent solutes and water from passing freely through the paracellular space between epithelial or endothelial cell sheets, and also play critical roles in maintaining cell polarity and signal transductions. This gene is upregulated in patients with ulcerative colitis and highly overexpressed in infiltrating ductal adenocarcinomas. PKC\/MAPK\/AP-1 (protein kinase C\/mitogen-activated protein kinase\/activator protein-1) dependent pathway regulates the expression of this gene in gastric cells. Alternatively spliced transcript variants encoding different isoforms have been identified.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003ctable style=\"width:100%; border-collapse:collapse;\"\u003e\n\u003ctr\u003e\n\u003cth style=\"text-align:left; vertical-align:top; padding:6px; border-bottom:1px solid #eee;\"\u003eFamily\u003c\/th\u003e\n\u003ctd style=\"padding:6px; border-bottom:1px solid #eee;\"\u003ePrimary antibody\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"text-align:left; vertical-align:top; padding:6px; border-bottom:1px solid #eee;\"\u003eFormulation\u003c\/th\u003e\n\u003ctd style=\"padding:6px; border-bottom:1px solid #eee;\"\u003e0.5mg\/ml if reconstituted with 0.2ml sterile DI water\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"text-align:left; vertical-align:top; padding:6px; border-bottom:1px solid #eee;\"\u003eFormat\u003c\/th\u003e\n\u003ctd style=\"padding:6px; border-bottom:1px solid #eee;\"\u003eAntigen affinity purified\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"text-align:left; vertical-align:top; padding:6px; border-bottom:1px solid #eee;\"\u003eHost Animal\u003c\/th\u003e\n\u003ctd style=\"padding:6px; border-bottom:1px solid #eee;\"\u003eRabbit\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"text-align:left; vertical-align:top; padding:6px; border-bottom:1px solid #eee;\"\u003eClonality\u003c\/th\u003e\n\u003ctd style=\"padding:6px; border-bottom:1px solid #eee;\"\u003ePolyclonal (rabbit origin)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"text-align:left; vertical-align:top; padding:6px; border-bottom:1px solid #eee;\"\u003eIsotype\u003c\/th\u003e\n\u003ctd style=\"padding:6px; border-bottom:1px solid #eee;\"\u003eRabbit IgG\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"text-align:left; vertical-align:top; padding:6px; border-bottom:1px solid #eee;\"\u003eSpecies Reactivity\u003c\/th\u003e\n\u003ctd style=\"padding:6px; border-bottom:1px solid #eee;\"\u003eHuman, Rat\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"text-align:left; vertical-align:top; padding:6px; border-bottom:1px solid #eee;\"\u003eApplication\u003c\/th\u003e\n\u003ctd style=\"padding:6px; border-bottom:1px solid #eee;\"\u003eWB, IHC-P, IF, FACS, Direct ELISA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"text-align:left; vertical-align:top; padding:6px; border-bottom:1px solid #eee;\"\u003eApplication Details\u003c\/th\u003e\n\u003ctd style=\"padding:6px; border-bottom:1px solid #eee;\"\u003eWestern blot: 1-2ug\/ml,Immunohistochemistry (FFPE): 2-5ug\/ml,Immunofluorescence (FFPE): 5ug\/ml,Flow cytometry: 1-3ug\/million cells,Direct ELISA: 0.1-0.5ug\/ml\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"text-align:left; vertical-align:top; padding:6px; border-bottom:1px solid #eee;\"\u003eApplication Note\u003c\/th\u003e\n\u003ctd style=\"padding:6px; border-bottom:1px solid #eee;\"\u003eOptimal dilution of the Claudin 18 antibody should be determined by the researcher.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"text-align:left; vertical-align:top; padding:6px; border-bottom:1px solid #eee;\"\u003eLocalization\u003c\/th\u003e\n\u003ctd style=\"padding:6px; border-bottom:1px solid #eee;\"\u003eCell membrane, cell junction\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"text-align:left; vertical-align:top; padding:6px; border-bottom:1px solid #eee;\"\u003eImmunogen\u003c\/th\u003e\n\u003ctd style=\"padding:6px; border-bottom:1px solid #eee;\"\u003eRecombinant human protein (amino acids S31-V261) was used as the immunogen for the Claudin 18 antibody.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"text-align:left; vertical-align:top; padding:6px; border-bottom:1px solid #eee;\"\u003eBuffer\u003c\/th\u003e\n\u003ctd style=\"padding:6px; border-bottom:1px solid #eee;\"\u003eLyophilized from 1X PBS with 2% Trehalose\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"text-align:left; vertical-align:top; padding:6px; border-bottom:1px solid #eee;\"\u003ePurity\u003c\/th\u003e\n\u003ctd style=\"padding:6px; border-bottom:1px solid #eee;\"\u003eAntigen affinity purified\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"text-align:left; vertical-align:top; padding:6px; border-bottom:1px solid #eee;\"\u003eStorage\u003c\/th\u003e\n\u003ctd style=\"padding:6px; border-bottom:1px solid #eee;\"\u003eAfter reconstitution, the Claudin 18 antibody can be stored for up to one month at 4oC.
