The binding of one protein to another provokes a variety of biophysical changes that can then be used as a measure of the binding reaction. Optical spectroscopy, particularly fluorescence, is the most flexible technique, but surface plasmon resonance biosensors, microcalorimetry and mass spectroscopy have recently shown significant development.

by-product of fisheries processing plants applicable protein. in this study effect of papain (plant origin), trypsin, pepsin (animal), alkalaz, prvtamks, flavrzaym (microbial), and temperatures of 30, 60, 90, 120, 150, and 180 minutes on the hydrolysis of rainbow trout waste were examined. the recovered peptone in the media as a source of bacteria lactobacillus plantarum and aeromonas hydrophil...

Aquaporins are tetrameric membrane-bound channels that facilitate transport of water and other small solutes across cell membranes. In eukaryotes, they are frequently regulated by gating or trafficking, allowing for the cell to control membrane permeability in a specific manner. Protein-protein interactions play crucial roles in both regulatory processes and also mediate alternative functions s...

we present the first reported case of antiphospholipid syndrome with stroke in an iranian boy (7-month-old) who had two ischemic strokes within a period of 2 months. serum anticardiolipid antibody was positive and the patient had low levels of protein s and c. this case emphasizes the importance of antiphospholipid antibody in children with unexplained ischemic stroke.
