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 اولCharacterization of membrane fractions and isolation of purified plasma membranes from rat myometrium.
Plasma membranes from rat myometrium preincubated in Krebs-Ringer solution and homogenized in a Polytron were isolated by differential and sucrose density gradient centrifugation. The enzyme activities of isolated plasma membranes were analyzed to determine the contamination by mitochondrial inner and outer membranes, endoplasmic reticulum, and lysosomes. The activities of succinate-cytochrome ...
متن کاملIsolation of plasma membranes from purified mouse spermatogenic cells.
Plasma membranes have been prepared from purified pachytene spermatocytes, round spermatids and residual bodies of the adult mouse testis using procedures modified from other authors'. Isolated membranes have been examined using electron microscopy, lectin binding and enzymic assays. Ultrastructural observation reveals smooth unit-membrane vesicles from 0.4-1.7 micrometer diameter. No contamina...
متن کاملCryopreservation of rooster sperm using methyl cellulose.
Experiments were designed to determine when, during the cryopreservation process, sperm lose fertilizing capacity and whether the cryoprotectant, methyl cellulose (MC), could be used in combination with glycerol to cryopreserve sperm and remain in the inseminate without reducing fertility. Semen diluted in Minnesota Avian extender (MNA) and inseminated immediately had greater fertility (75%) th...
متن کاملLipid composition and thermotropic phase behavior of boar, bull, stallion, and rooster sperm membranes.
Composition and thermotropic phase behavior of sperm membrane lipids from species ranging in sensitivity to cold shock were determined. Lipids from whole sperm and sperm plasma membrane were fractionated into neutral lipid, glycolipid, and phospholipid fractions. Compositional analyses were completed for free sterols, phospholipids and phospholipid-bound fatty acids. Phase transition temperatur...
