"The loop-mediated isothermal amplification (LAMP) method was developed to distinguish between the varicella-zoster virus (VZV) vaccine (vOka) strain and wild-type strains. Two single nucleotide polymorphisms (SNPs) (nucleotide [nt] 105705 for VR-1 VZV LAMP and nt 106262 for VR-2 VZV LAMP) located in the open reading frame 62 gene were selected as LAMP targets," scientists in Japan report. "Amplified vOka DNA demonstrated a typical ladder pattern; however, no LAMP product was detected in reactions performed with DNAs from other human herpesviruses by either VR-1 VZV LAMP or VR-2 VZV LAMP. This result was confirmed by a turbidity assay. The sensitivities of both VR-1 and...
