                Application 10/260,733                                                                         
                 [34] Further according to Kuukasjärvi, "CGH analysis showed that 50 pg                        
                      of DNA (corresponding roughly to two hypertetrapoloid MCF-7 cells)                       
                      was sufficient to produce copy number profiles, which were identical                     
                      to those obtained from a standard CGH protocol" (Kuukasjärvi at 97).                     
                 [35] PCR-based incorporation of fluorescent markers (labeled nucleotides)                     
                      was said "to be very effective and resulted in a high signal intensity in                
                      CGH" (Kuukasjärvi at 100).                                                               
                 [36] Kuukasjärvi "concludes that CGH can now be efficiently used to                           
                      analyze DNA sequence gains and losses in small subpopulations of                         
                      cells from, e.g., premalignant and early lesions" (Kuukasjärvi at 100).
