Summary: Metal ions can inhibit PCR in forensic DNA analysis, especially in samples from crime scenes. Zinc, tin, iron(II), and copper show strong inhibitory effects on DNA amplification, while KOD polymerase exhibits the highest resistance to metal inhibition. Ethylene glycol-bis(2-aminoethylether)-N,N,N ',N '-tetraacetic acid (EGTA) can effectively reverse calcium-induced PCR inhibition.

Summary: Synthetic cannabinoid receptor agonists (SCRAs) primarily act through human type-1 cannabinoid (CB1) receptors. The study analyzed enantiomer pairs of SCRA samples seized in Scottish prisons and found that (S)-enantiomers are more potent and efficacious than (R)-enantiomers. The importance of SCRA-CB1 receptor interactions and the impact of the chiral tert-leucinate group on potency were highlighted.
