Enhanced Hybridization Selectivity Using Structured GammaPNA Probes
High affinity nucleic acid analogues such as gammaPNA (γPNA) are capable of invading stable secondary and tertiary structures in DNA and RNA targets but are susceptible to off-target binding to mismatch-containing sequences.

COMPARATIVE STUDY OF THE HOP BITTER ACIDS ANALYSIS METHODS
A single laboratory validation study (SLV) was conducted for an conductometric method for the determination of total hop acids in pellets from different variety. Extraction variants were developed in accordance with Analytica EBC 7.4 which is identical with Romanian Standard SR 13842:2003, where the extraction solvent is toluene (Extraction System A)
