Figure 4From: Loss of aquaporin-4 expression and putative function in non-small cell lung cancer Western blot analyses of AQP4 in normal lung and adenocarcinomas. This western blot clearly demonstrates the expression of both the M1 (34 kDa) and the array-forming M23 variant (31 kDa) of AQP4 in normal lung (N) and adenocarcinomas (AC).Back to article page
