COT I Human DNA is prepared from human placental DNA by shearing, denaturing, and reannealing under conditions that enrich these repetitive elements. The
product is similar to Invitrogen #15279.
The product is prepared from male human placental DNA, exclusively.
The Cot-I DNA fraction of human genomic DNA consists largely of rapidly annealing repetitive elements. These interspersed repetitive sequences (IRS), such as SINEs (small interspersed repetitive
elements, e.g., Alu elements) and LINEs (large interspersed repetitive elements, e.g., L1 elements),are distributed ubiquitously throughout the genome.
