Alpha-cyano-4-hydroxycinnamic acid (alpha-CHCA) as a matrix facilitates the ionization of proteins and peptides in a matrix-assisted laser desorption/ionization (MALDI) time-of-flight (TOF) mass spectrometer. The matrix itself also ionizes and so do its sodium and potassium adducts. Matrix clusters and metal

We hypothesized that BBB is impaired in rat model of streptozotocin-induced diabetes and can be sealed by poly(amido)amine dendrimers G4.0 (PAMAM G4), which reveal anti-glycation activity. The BBB permeabilization was monitored in rats with the 60-day streptozotocin-diabetes and non-diabetic animals

One of the most important aspects of our ultra-pure MALDI matrix substances is their ability to dissolve rapidly and completely; a brief vortex mixing is typically sufficient.
