I valori di pH di tutti i tamponi dipendono dalla temperatura e dalla concentrazione. Per i tamponi Tris, a ogni °C di diminuzione della temperatura corrisponde un aumento di circa 0,03 unità di pH, mentre a ogni diluizione di un fattore 10 corrisponde una diminuzione di 0,03-0,05 unità di pH. Per applicazioni che necessitano di estrema precisione, utilizzare un pH-metro accuratamente calibrato con un elettrodo combinato vetro/calomelano.

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

We developed a human skin equivalent (HSE) containing blood and lymph-like capillary networks using a cell coating technique, which is a rapid fabrication technology of three-dimensional cellular constructs by cell surface coating using layer-by-layer assembled nanofilms of extracellular matrices. The
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

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.
Redi-Dri™ prevents hygroscopic powders, such as inorganic salts, from absorbing moisture and forming clumps, leaving the salts free-flowing every time.
