From: APOL1 genotyping via buccal mucosa cell samples to establish risk of kidney disease
Analysis of PCR products obtained from the amplification of an APOL1 gene segment by agarose gel electrophoresis
PCR was carried out using DNA extracted from blood and buccal mucosa cell samples from all 23 patients. PCR products (10µL) from blood (A) and buccal mucosa cell samples (B) were analyzed by agarose gel electrophoresis using 1% agarose gels containing 1 µg/mL ethidium bromide. Representative examples of the tested samples are shown. Black arrowheads indicate molecular weight markers, while red arrowheads correspond to amplified PCR products (DNA bands approximately 422 bp long), respectively
