Application

D-Val-Leu-Lys p-nitroanilide dihydrochloride has been used:
  • as substrate to measure the activity of plasminogen activator by a chromogenic assay
  • as a p-nitroanilide (pNA) substrate to measure the specific activities of serine protease isoforms in Gloydius intermedius venom
  • as a substrate in total plasmin assay using milk/cream samples

Despite membrane-based separations offering superior alternative to packed bed chromatographic processes, there has been a substantial lacuna in their actual application to separation processes. One of the major reasons behind this is the lack of availability of appropriately modified or

Nine distinct venom serine proteases (vSPs) of Gloydius intermedius were studied by transcriptomic, sub-proteomic and phylogenetic analyses. Their complete amino acid sequences were deduced after Expression Sequence Tag (EST) analyses followed by cDNA cloning and sequencing. These vSPs appear to

The shelf life of pasteurized milk is limited by heat-stable proteases, which cause gelation and bitter taste upon extended storage of milk. Ultra-high temperature processing inactivates proteases but detrimentally affects milk's sensory quality. An adjunct to pasteurization is desired to
