其他说明
所有缓冲液的pH值都与温度和浓度有关。对于 Tris 缓冲液，温度每降低 1°C，pH 就会增加约 0.03 单位，每稀释 10 倍，pH 会降低 0.03-0.05 单位。对于一些精准的应用，请使用经过仔细校准的pH计和玻璃/甘汞组合电极。

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

Our present work aimed at developing a pseudo triple-enzyme cascade electrocatalytic electrochemical aptasensor for determination of thrombin with the amplification of alcohol dehydrogenase (ADH)-Pt-Pd nanowires bionanocomposite and hemin/G-quadruplex structure that simultaneously acted as NADH oxidase and HRP-mimicking DNAzyme. With the

Tight junctions play a critical role in the maintenance of intestinal barrier function. Partitioning-defective protein 3 (Par-3) can regulate intestinal barrier function through the modulation of tight junction assembly and cell polarity. However, the mechanisms are still not fully understood.

NAP (NAPVSIPQ, davunetide) is a microtubule stabilizing peptide drug candidate. Here, we set out to identify NAP-like peptides that provide neuroprotection and reduce tau pathology. NAP-like peptides were derived using publically available search engines, which identified sequence homologies in the
