human ... ABCB1(5243)
Specificity
Reacts with a conserved cytoplasmic epitope of the plasma membrane-associated 170 kDa P-gp, member of the superfamily of transmembrane transporters. JSB-1 detects P-gp overexpression in human tumor cells of all different histogenetic derivations.
JSB-1 does not cross-react with MDR3 P-glycoprotein. JSB-1 has been shown to cross-react with Pyruvate Carboxylase (PC), an abundant Mr 130,000 mitochondrial enzyme, on both immunoblots and immunohistochemical tissue sections [Rao et al. (1995). J Histo. Cytochem. 43(12):1187-1192.] Unequivocal plasma membrane patterns of immunostaining represent true P-glycoprotein ex-presssion. Weak homogeneous, cytoplasmic, or granular patterns of reactivity may represent staining of the PC cross-reactive epitope rather than positive staining for P-glycoprotein.
