Long interspersed repetitive elements LINEs

Additional analysis of DNA sequences in the human genome has revealed that large blocks of human genes are filled with repeated elements, including long interspersed repetitive elements (LINEs) and short interspersed repetitive elements (SINEs). Short interspersed repetitive elements such as Alu sequences are often used as target sequences for DNA fingerprinting. 

This method is useful for the isolation of interspersed repetitive DNA elements whose copy number is on the order of tens of thousands, but it will not be practical for the isolation of less abundant elements. As long as the copy number is high enough, SINEs, LINEs, and the retroviral-like elements can all be isolated using this approach.
