متن کاملSome Biochemical and Electrophoretic Studies on Purified Prothrombin , Factor VII (
S TUDIES of the chemical nature of prothrombin have indicated a glycoprotein structure.2 Data obtained on purified bovine prothrombin have shown the reducing sugar content to be approximately 5 per cent, based on a reference standard of galactose and mannose.35 Laki et al.5 reported a value of 6.5 per cent in terms of glucose, and 1.6 to 1.7 per cent hexosamine. Alexander6 and colleagues observ...

متن کاملStudies on Aspergillus Section Flavi from Peanut in Iran
During 2010 and 2011, Aspergillus species from section Flavi were isolated from rhizosphere in main peanut-growing region of Iran, Astaneh-e Ashrafiyeh, Guilan Province (northern Iran). The soil samples were taken from fruiting zone of peanuts in 3 districts and 10 locations, during the pod-filling period. The populations of Aspergillus section Flavi showed significant differences in cfu g-1 am...
متن کاملextraction 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 ...
