Oncofetal Antigen 5T4, ID (TPBG, Trophoblast Glycoprotein, 5T4 Oncofetal antigen, 5T4 Oncofetal Trophoblast Glycoprotein, M6P1) (Biotin)

Human 5T4 (oncofetal antigen 5T4; also TPBG and trophoblast glycoprotein) is a 72kD glycoprotein member of the LRR family of proteins. It is expressed on trophoblasts, tumor cells, ovarian cuboidal epithelium and embryonic stem cells, and impacts cell adhesion and motility. The human 5T4 cDNA encodes a type I transmembrane protein precursor that is 420aa in \nlength. It contains a 324aa extracellular region (aa32-355) that shows one Ser-rich region followed by seven Leu-rich repeats (aa90-355). Over aa31-355, human 5T4 shares 81% and 85% aa identity with mouse and canine 5T4, respectively. \n\nApplications: \nSuitable for use in Western Blot. Other applications not tested.\n\nRecommended Dilutions:\nWestern Blot: 0.1-0.2ug/ml. The detection limit is ~5ng/lane under non-reducing and reducing conditions. ~20% crossreactivity with recombinant mouse 5T4.\nOptimal dilutions to be determined by the researcher.\n\nStorage and Stability:\nLyophilized powder may be stored at -20 degrees C. Stable for 12 months at -20 degrees C. Reconstitute with sterile TBS, pH 7.3, 0.1% BSA. Aliquot to avoid repeated freezing and thawing. Store at -20 degrees C. Reconstituted product is stable for 12 months at -20 degrees C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.
