Abstract (en)

[origin: WO9612824A2] An improved method of amplifying target nucleic acids and particularly, to a method of alleviating the inhibitory effect of certain samples on ligase chain reaction amplifications. The relief of inhibition is accomplished by adding to the amplification mixture a polyamine reagent such as spermidine, in effective amounts, typically 1 to 4 nM. In other embodiments, the presence of spermidine allows for amplification to proceed in the presence of reduced concentrations of MgCl2 and ligase.
