Zusammenfassung:Reaction condition compositions for detecting a genomic variation from a small sample amount from 5 nano grams (ng) to 1 microgram (ug) includes DNA ligase, DNA polymerase, at least one COP, a DNA polymerase buffer, NAD+, at least two primers, and deoxynucleotide triphosphates (dNTPs). Detection of the genomic variation utilizes COPs with increased ligation efficiency and RCA with fluorescence detection due to simultaneous ligation of COPs to CPs and replication of the genomic variation. The reaction condition composition eliminates the need to perform background reduction of un-hybridized or un-ligated COPs.
