应用

所有缓冲液的pH值都与温度和浓度有关。对于Tris缓冲液，降温每℃其pH值约增加0.03单位，每10倍稀释其pH降低0.03-0.05单位。
对于精确的应用，请使用带有玻璃/甘汞组合电极并仔细校准过的pH计。

The content of biogenic compounds and the biological activities of barley (Hordeum vulgare L.)-grain extracts was evaluated. The sufficiently large and heterogeneous set of barley genotypes (100 accessions) enabled the selection of special genotypes interesting for potential industrial, pharmaceutical, and

A new gold particles modified heated copper disk electrode (Au-HCuDE) with direct current was fabricated. The hemin/G-quadruplex horseradish peroxidase-mimicking DNAzyme (HRP-DNAzyme) was self-assembled on the heated electrode and resulted in a new biosensor denoted as HRP-DNAzyme/Au-HCuDE.
