extraction and acetylation of purified trypsin from bovin pancreas and study of some its physico-chemical properties
آنزیم تریپسین در شرایط قلیایی ناپایدار می باشد .و فعالیت پروتئولیتیکی تریپسین منجربه خود هضمی آن در جایگاههای خاصی می گردد. بنابر این آنزیمی با ناپایداری بالا محسوب میگردد. در سالهای اخیر موفق شدند که با ایجاد تغیرات شیمیایی با اضافه کردن فلزات خاص ، کلسیم و یا عمل استیلاسیون منجر به افزایش پایداری آنزیم تریپسین گردند. مطالعات در حال حاضر نشان می دهد که تریپسین استیله شده فعالیت آنزیمی خود را ...
15 صفحه اولPreparation of antibody conjugates
Enzymes, fluorochromes and other marker molecules are commonly used in a variety of applications to provide specific detection signals. To this aim, they may be conjugated to antibodies, avidin, protein A or G and other proteins in many ways. Fundamental work on chemical modification of proteins and antibody labelings has already been done long before AH COONS and co-workers employed those tech...
متن کاملReaction of Allicin-related Compounds with Protein.
protein in vitro and also with body constituents in vivo. They assumed that allicin was not chemically bound with the SH groups of protein, but it was additionally bound forming a complex. Allicin was not liberated from the "com plex" by washing with water or saturated ammonium sulfate solution, but could be easily separated by extracting with ethanol in which allicin is easily soluble. When pr...
متن کاملAllicin: chemistry and biological properties.
Allicin (diallylthiosulfinate) is a defence molecule from garlic (Allium sativum L.) with a broad range of biological activities. Allicin is produced upon tissue damage from the non-proteinogenic amino acid alliin (S-allylcysteine sulfoxide) in a reaction that is catalyzed by the enzyme alliinase. Current understanding of the allicin biosynthetic pathway will be presented in this review. Being ...
متن کاملPreparation and characterization of detoxified lipopolysaccharide-protein conjugates.
Alkaline treatment of Pseudomonas aeruginosa type 5 lipopolysaccharide (LPS) resulted in reduced toxicity as measured by both the Limulus amoebocyte assay and the rabbit pyrogenicity test. Chemical analysis of the deacylated LPS (D-LPS) revealed that ester-linked fatty acids were removed while the amide-linked fatty acids remained intact. The neutral and amino sugar compositions for native LPS ...
