The autoactivation of trypsinogen.
The ability of trypsinogen to catalyze its own activation was studied at pH 8.1 in the presence of Ca++ ions. The lag phase portion of the classical S-shaped curve of activation was shortened by increasing the trypsinogen concentration but was extended by pretreatment of the zymogen with diisopropyl fluorophosphate or soybean trypsin inhibitor. Despite these pretreatments, however, full activat...
متن کاملSynthesis of high molecular weight polyethylene using FI catalyst
A FI Zr-based catalyst of bis[N-(3,5-dicumylsalicylidene)-2′,6′diisopropylanilinato]zirconium(IV) dichloride was prepared and used for polymerization of ethylene. The effects of reaction conditions on the polymerization were examined in detail. The increase in ethylene pressure and rise in polymerization temperature up to 35 oC were favorable for catalyst/MAO to raise the catalytic activity as...
متن کاملThe Molecular Weight of Antibodies
1. Highly purified preparations of homogeneous antibody can be made by the salt dissociation methods (6, 7) without any change in sedimentation due to the method of purification. 2. Antibodies prepared from sera of various animal species fall into two groups as regards molecular weight; in one group cow, horse, and pig, a heavy molecule of molecular weight 990,000 is formed; in human being, rab...
متن کاملThe Molecular Weight of Antibodies
1. Highly purified rabbit Type III pneumococcus anticarbohydrate proved to be homogeneous in the ultracentrifuge and its sedimentation constant, 7.0.10(-13), did not differ from that of the principal component of normal rabbit globulin or of immune rabbit globulin containing up to 50 per cent of anti-egg albumin. The molecular weight of antibody in the rabbit is therefore probably very close to...
متن کاملthe effect of taftan pozzolan on the compressive strength of concrete in the environmental conditions of oman sea (chabahar port)
cement is an essential ingredient in the concrete buildings. for production of cement considerable amount of fossil fuel and electrical energy is consumed. on the other hand for generating one tone of portland cement, nearly one ton of carbon dioxide is released. it shows that 7 percent of the total released carbon dioxide in the world relates to the cement industry. considering ecological issu...
