Serine phosphoric acid from diisopropylphosphoryl derivative of eel cholinesterase.
Diisopropyl fluorophosphate (DFP) is a highly specific inactivator of e&erases, such as cholinesterase and chymotrypsin (2), and combines irreversibly with these enzymes (3,4). In a previous report from this laboratory (5) we have shown that, when the reaction product of DFP and chymotrypsin, namely, diisopropylphosphoryl chymotrypsin, is partially hydrolyzed, serine phosphoric acid may be obta...
متن کاملRate of production of P32-labeled lymphocytes.
E BULK OF DATA initially accumulated regarding the lymphocyte tended to indicate that its life span was relatively short. Thus, Minot and Isaacs,’ in 1925, transfused blood from a patient with chronic lymphocytic leukemia into a patient with lymphosarcoma. The recipient’s blood showed an elevated lymphocyte count for 35 minutes before returning to normal. Yoffey,2 in 1935, showed that in the do...

متن کاملPhysicochemical Properties of β-Glucan from Acid Hydrolyzed Barley
This study was performed to investigate changes in the content and purity, as well as physical characteristics of β-glucan extracted from acid hydrolyzed whole grain barleys. Waxy and non-waxy barleys (Hordeum vulgare) were hydrolyzed with different concentrations of HCl (0.1~0.5 N) for 1 h. As the HCl concentration increased, the contents of total and soluble β-glucan from acid hydrolyzed barl...
متن کاملPulmonary transcapillary exchange of Na24 and P32-labeled phosphate in pulmonary emphysema.
In previous studies it was observed that 5 to 20 per cent of intravenously administered Na24 and P32-labeled phosphate and other electrolytes escaped from the circulation during a single transit through the cardiopulmonary pool (1). The relatively small transcapillary exchange of electrolytes in the lungs as compared with skeletal muscle and certain other viscera was attributed to a lesser perm...
