Radiometric assay for direct quantitation of rat liver cytochrome P-450b using monoclonal antibodies
(Elsevier, 1985-08-15)
A simple and sensitive assay has been developed that is capable of detecting as little as 0.2 ng of the major isozyme of cytochrome P-450 (P-450b) isolated from the livers of phenobarbital-induced rats. This assay employs ...
Carbohydrate-binding specificity of the daffodil (Narcissus pseudonarcissus) and amaryllis (Hippeastrum hybr.) bulb lectins
(Elsevier, 1990-06)
The carbohydrate binding specificity of the daffodil (Narcissus pseudonarcissus; NPA) and amaryllis (Hippeastrum hybr.; HHA) lectins, isolated from extracts of their bulbs by affinity chromatography on immobilized mannose, ...
Protein-carbohydrate interaction : V. Further inhibition studies directed toward defining the stereochemical requirements of the reactive sites of concanavalin A
(Elsevier, 1967-07)
Inhibition studies on the concanavalin A-dextran interaction have been extended using as inhibitors the members of the maltose-, isomaltose-, and methyl [alpha]-isomaltoside series, amino and N-acetyl amino sugars, and a ...
Cumene hydroperoxide-supported denitrification of 2-nitropropane in uninduced mouse liver microsomes
(Elsevier, 1986)
1. 1. Cumene hydroperoxide supported oxidative denitrification of 2-nitropropane was investigated in uninduced mouse liver microsomes.2. 2. The cytochrome P-450 peroxygenase catalyzed reaction resulted in the production ...
Somatostatin in human pancreatic and gastric juice
(Elsevier, 1981)
Considerable amounts of IRS are secreted after secretin injection in human pancreatic juice collected during endoscopic retrograde cholangiopancreatography. The mean IRS levels in the pancreatic juice of non-diabetic ...
Synthesis and properties of 35S, 14C and 3H labeled S-alkyl glycerol ethers and derivatives
(Elsevier, 1976-07)
Radioactive S-alkyl glycerol ethers have been synthesized with 35S, 14C and 3H labels as well as 3H/35S double labels.The synthesized compounds were converted to various derivatives which can serve to characterize the ...
A chemical approach to solving bridging phenomena in steroid radioimmunoassays
(Elsevier, 1981-08)
Steroid radioimmunoassays (RIA) employ antibodies raised against a carrier protein-steroid conjugate. Individual antibodies may recognize the steroid, the protein or the chemical bridge used to Join them together. Use of ...
Rat liver membrane preparations
(Elsevier, 1972-09)
The quality of rat liver plasma membranes was examined using three different methods of preparation. Hypotonic Ca++-free preparation media were compared with hypotonic Ca++ media and with isotonic Ca++ media. The plasma ...
