{"product_id":"nsj-cd133-antibody-primary-antibody","title":"CD133 Antibody","description":"\u003cp\u003eThe CD133 gene codes for a pentaspan transmembrane glycoprotein. The CD133 antigen appears to belong to a new molecular family of 5-TM proteins, as the characterization of the CD133 antigen and prominin in the mouse were the first descriptions of a 5-TM glycoprotein structure. This 'family' includes members from several different species (which may be homologs) including human, mouse, rat, fly, and worm. The 5-TM structure includes an extracellular N-terminus, two short intracellular loops, two large extracellular loops and an intracellular C-terminus CD133 was initially shown to be expressed on primitive hematopoietic stem and progenitor cells and retinoblastoma. CD133 has since been shown to be expressed on hemangioblasts, and neural stem cells as well as on developing epithelium. Expression patterns for CD133 generally mimic those of the murine prominin molecule, although CD133 antigen has not yet been demonstrated on adult epithelial tissue. The CD133 positive fraction of human bone marrow, cord blood and peripheral blood have been shown to efficiently engraft in xenotransplantation models, and have been shown to contain the majority of the granulocyte\/macrophage precursors, NOD\/SCID repopulating cells and CD34 + dendritic cell precursors. Phenotypically, CD133 positive cells in blood and marrow are CD34 bright, with CD34 dim CD71 bright cells being negative for CD133 expression. Many leukemias express CD133 as well as CD34 , but some investigators have noted leukemic blasts which are CD133+ and CD34 negative. No natural ligand has yet been demonstrated for the CD133 molecule, and its function in hematopoietic tissue is unknown.\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;\"\u003eIn 1X PBS, pH 7.4, with 0.09% sodium azide\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;\"\u003ePurified\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 Ig\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\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, IF, IHC-P, FACS\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: 1:500-1:2000,Immunofluorescence: 1:25,Immunohistochemistry (FFPE): 1:25,Flow cytometry: 1:25 (1x10e6 cells)\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;\"\u003eThe stated application concentrations are suggested starting points.
