Chitosan nanoparticles conjugate with trypsin and trypsin inhibitor
Carbohydrate Polymers, 2016Chitosan-protein conjugates are widely used in therapeutic drug delivery. We report the bindings of chitosan nanoparticles with trypsin (try) and trypsin inhibitor (tryi), using thermodynamic analysis and multiple spectroscopic methods. Thermodynamic parameters ΔS, ΔH and ΔG showed chitosan-protein bindings occur mainly via H-bonding and van der Waals ...

Trypsin Uptake and Trypsin-Inhibitor Complexes
Neonatology, 1989Previous studies have suggested that both newborn animals and humans absorb intact proteases from the intestine in greater amounts than do adults. Absorbed proteases are rapidly complexed in plasma by several inhibitors which inactivate free proteases. In order to confirm increased intestinal uptake in newborns, we evaluated the plasma trypsin activity

CELLS ISOLATED FROM TRYPSIN‐TREATED BRAIN CONTAIN TRYPSIN
Journal of Neurochemistry, 1976Abstract—Neuronal and oligodendroglial cell fractions isolated from trypsinized brain contain trypsin. Neuronal cell bodies contained approximately 5 μg of trypsin/mg of cell protein; oligodendroglial cells had approx 1 μg of enzyme activity. Studies with fluorescein‐conjugated trypsin suggested that least a portion of the fluorescent enzyme was ...

Tumour-associated trypsin inhibitor and tumour-associated trypsin
Scandinavian Journal of Clinical and Laboratory Investigation, 1990Tumour-associated trypsin inhibitor (TATI) is a 6 kDa peptide, which is synthesized at low concentrations by several tumours and cell lines. Very high concentrations of TATI occur in mucinous ovarian tumours. Elevated levels of TATI occur in serum and urine in connection with most types of cancer at advanced stages. In mucinous ovarian cancer up to 85%
