objective(s): snake venoms contain complex mixture of proteins with biological activities. some of these proteins affect blood coagulation and platelet function in different ways. snake venom toxin may serve as a starting material for drug design to combat several pathophysiological problems such as cardiovascular disorders. in the present study, purification of anticoagulation factor from veno...
For the preparation of greatly detoxified but highly immunogenic toxoids, two enzymatically active, low-toxicity derivatives of Pseudomonas aeruginosa exotoxin-A were further inactivated by photoaffinity labeling. These derivatives were formed during toxin purification, when a relatively crude toxin preparation was concentrated by ammonium sulfate precipitation and subsequently dialyzed. These ...
3-Hydroxypropyl flufenamide (Flu-HPA) is one of a series of flufenamic acid derivatives that enhances blood clot lysis in vitro. Studies of possible mechanisms of action of FIu-HPA were undertaken. The profibrinolytic activity of FIu-HPA in clot lysis assays was found to be dependent on plasminogen. The influence of FIu-HPA on the ability of purified a2-antiplasmin to inhibit purified plasmin w...
1. Pure rabbit bone metalloproteinase inhibitor (TIMP) bound tightly to pure rabbit bone collagenase with an apparent Kd of 1.4 X 10(-10) M. 2. The molecular weight of the enzyme-inhibitor complex was found to be 54 000, but no enzyme activity could be recovered from the complex after treatment with either mercurials or proteinases. The complex thus differed from latent collagenase in terms of ...
Production of purified DME by reactive distillation was demonstrated experimentally and the first validated process simulation model in literature for this derived.
Cloning and expression of the L-phenylalanine dehydrogenase gene, from B. sphaericus in E. coli were done. The gene was cloned in the vector pET16b and transformed into E. coli BL21 (DE3). The functional form of the L-phenylalanine dehydrogenase enzyme was purified by affinity purification techniques, taking advantage of the ability of this enzyme to bind to the nucleotide site affinity dye, Re...
Avian influenza (AI) H9N2 is a low pathogenic virus subtype belonging to Orthomyxoviridae family. Given the prevalence of this subtype as an infectious agent in poultry industry, special attention has been always directed toward the development of vaccine production against this infection. The vaccine of this infection is produced by killing the virus and using a mixture of inactivated antigen ...
