Assay notes:	Represents isoform B.

Structure	Level	Pattern	Image	Note
TS28: renal cortex	Strong		3D	Most highly expressed.
TS28: outer renal medulla	Present		3D	Minor hybridization signal, probably reflected cross-hybridization with the much more abundant F isoform.

Structure	Level	Pattern	Image	Note
TS28: cortical renal tubule	Present	Regionally restricted	4A	Expressed in a subpopulation of tubules that were in direct contact with the vascular poles of glomeruli, as well as tubules that extended from the outer medulla toward glomeruli.
TS28: glomerular tuft	Absent		4A
TS28: renal proximal convoluted tubule	Absent		4A
