40Multiplex ligation-dependent probe amplification — (MLPA)[1] is a variation of the polymerase chain reaction that permits multiple targets to be amplified with only a single primer pair[1]. Each probe consists of a two oligonucleotides which recognise adjacent target sites on the DNA. One probe… …
