The present study evaluated the enzymes AmpliTaq Gold, HotStarTaq Plus, KAPA3G Plant, and KAPA2G Robust, with regard to their ability to overcome inhibitory effects.  However, the largest impact was observed when alternative enzymes were utilized, instead of the commonly used AmpliTaq Gold. 
AmpliTaq Gold
The present study evaluated the enzymes AmpliTaq Gold, HotStarTaq Plus, KAPA3G Plant, and KAPA2G Robust, with regard to their ability to overcome inhibitory effects. 
HotStarTaq Plus
The present study evaluated the enzymes AmpliTaq Gold, HotStarTaq Plus, KAPA3G Plant, and KAPA2G Robust, with regard to their ability to overcome inhibitory effects.  Moreover, the KAPA3G Plant enzyme had the highest efficiency in amplifying degraded DNA from old buried bone material.  KAPA3G Plant and KAPA2G Robust may thus be useful for counteracting inhibitors and improving the analysis of challenging samples.
KAPA3G Plant
The present study evaluated the enzymes AmpliTaq Gold, HotStarTaq Plus, KAPA3G Plant, and KAPA2G Robust, with regard to their ability to overcome inhibitory effects.  KAPA2G Robust presented the highest amplification efficiency in the presence of the inhibitor ammonium nitrate.  KAPA3G Plant and KAPA2G Robust may thus be useful for counteracting inhibitors and improving the analysis of challenging samples.
