The development of the marine aquaculture industry has led to the generation of significant amounts of fish wastes. Marine farm wastes exert adverse effects on the surrounding area of the cages. On the other hand, wastes of fish and other aquatic animals are regarded as major sources of valuable natural bioactive compounds, including enzymes, proteins, bioactive peptides, oil, amino acids, coll...

Trypsin (E.C.3.4.21.4) is a serine protease commonly used in proteomics for digestion of proteins. In the present study, the effect of nano-TiO2 on the conformation and catalytic activity of trypsin were studied. The thermal denaturation of trypsin has been investigated in the presence and absence of nano-TiO2 over the temperature range (293-373 K) at pH 3.0 and 7.25, using temperature scanning...

background:   astrocytes are cells within the central nervous system which are activated  in a wide spectrum of infections,  and  autoimmune and  neurodegenerative diseases.in pathologic states, they produce  inflammatory cytokines, chemokines,  and  nitric oxide (no), and sometimes  they induce apoptosis.their protease-activated receptors (pars) can be activated by proteases, e.g.thrombin and ...

Antimicrobial therapy remains to be the most important method of wound infection treatment. Systemically administered antimicrobials may not achieve therapeutic level in wound. On the other hand, in the absence of surgical debridement (due to any reason), most topically applied antimicrobials cannot penetrate the wound in therapeutic amount due to the presence of eschar. Burn eschar is a protei...

the date palm fruit stalk borer is one of the most important pests of date palm in the world. biochemical properties of digestive proteases in oryctes elegans prell larvae were investigated in this research and optimal total proteolytic and trypsin activities were obtained at ph 9.0 and 11.0, respectively. activity staining of protease on sds-page showed one isoform. also, zymogram pattern of t...

trypsin is a serine protease found in the digestive system of many vertebrates, where it hydrolyses proteins. trypsin has been used widely in various biotechnological processes. in this study trypsin was purified using two precipitation cut, 35% and 75% as saturation percent of ammonium sulfate solutions, tca precipitation (2.5% w/v), ph precipitation and finally affinity chromatography. this m...

Peptide mapping is routinely used in the characterization of monoclonal antibodies (mAbs) for confirmation primary sequence and detection post-translational modifications (PTMs). Trypsin one most commonly proteases peptide protocols due to its high level specificity. However, it has been observed that trypsin alone not always sufficient full coverage because presence long sequences hydrophobic ...
