Fig. 4From: Selective measurement of α smooth muscle actin: why β-actin can not be used as a housekeeping gene when tissue fibrosis occursSanger sequencing chromatograms of PCR products amplified by mα-SMASD and mß-actinSD primer pairs. cDNA samples derived from kidneys of mice underwent unilateral ureteral obstruction were amplified using mα-SMASD or mß-actinSD primer pair and products were sequenced (a). Nucleotide homology between the sequence of our PCR products and the known CDSs of mouse α-SMA or ß-actin was complete (b)Back to article page
