Partial physico-chemical and immunological characterization of bovine semen isoantigens.
Antisera prepared by immunizing 10 virgin heifers with semen pooled from eight bulls of four dairy breeds reacted in immunodiffusion tests to indicate that bovine semen contains at least four isoantigens. No visible precipitin reaction was observed when such sera were diffused against vesicular gland fluid, but all four antigens were present in the testicular fluid, cauda epididymal plasma, cau...

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 اولPurification and partial characterization of human lymphoblast interferon.
One component of human lymphoblastoid interferon obtained from Namalwa cultures induced by Newcastle disease virus has been purified to a specific activity of 2.5 x 10(8) interferon units per mg of protein (protein content based on amino acid analysis). A single polypeptide species with an apparent molecular weight of 18,500 comigrating with the antiviral activity was observed by sodium dodecyl...
متن کاملPartial Purification and Characterization
An enzyme fraction containing phosphatase activity for phosphorylated eukaryotic peptide initiation factor 2 (eIF-2) has been isolated from rabbit reticulocytes and partially characterized, The enzyme efficiently catalyzes release of phosphate from the small subunit of eIF-2 (eIF-2a) that has been phosphorylated by the hemin-controlled repressor. It is shown to restore activity of this phosphor...
متن کاملCharacterization and Partial Purification
A bstract. Platelets have been shown to affect the growth of vascular endothelial cells. This report describes the characterization and partial purification from human platelets of a novel growth factor which can stimulate human endothelial cells to synthesize DNA and grow. Platelets were lysed by sonication and the particulate fraction removed by ultracentrifugation at 100,000 g. The supernata...
