Fig 3. Alu 115bp (ALU115) and 247bp (ALU247) PCR primer designs.

Fig 3

Forward and reverse primers of ALU115 are indicated by green text, ALU247 primers by orange text. Brackets indicate the size of fragments (140–200 bp) generated by enzymatic apoptotic cleavage as compared to the total length of the Alu element. ALU115 primers amplify apoptotic and longer DNA fragments, while ALU247 primers only amplify sequences longer than apoptotic DNA.
