2-Substituted methyl [alpha]--galactopyranosides: Synthesis and binding affinity for the A and B subunits of the Griffonia simplicifolia I isolectins
(Elsevier, 1985-07-01)
The binding affinities of the N-acetyl, N-trifluoroacetyl, N-propionyl, N-formyl, N-benzoyl, N-p-nitrobenzoyl, N-p-aminobenzoyl, and N-methyl derivatives of methyl 2-amino-2-deoxy-[alpha]--galactopyranoside and the 2-O-acetyl, ...
Immunochemical studies on the binding specificity of the blood group Leb specific lectin Griffonia simplicifolia IV
(Elsevier, 1983-05)
The specificity of the Griffonia simplicifolia IV (GS-IV) lectin was studied by quantitative precipitin and quantitative precipitin inhibition assays. The lectin precipitated most strongly with a human H,Leb blood group ...
A structural comparison of the A and B subunits of Griffonia simplicifolia I isolectins
(Elsevier, 1984-02-15)
A structural comparison between the A and B subunits of the five tetrameric Griffonia simplicifolia I isolectins (A4, A3B, A2B2, AB3, B4) was undertaken to determine the extent of homology between the subunits. The first ...
Binding of Griffonia simplicifolia I lectin to rat pulmonary alveolar macrophages and its use in purifying type II alveolar epithelial cells
(Elsevier, 1986-01-23)
We report that the isolectin Griffonia simplicifolia I-B4 isolated from G. simplicifolia seeds binds to rat alveolar macrophages present in frozen sections of lung tissue or bronchoalveolar lavage fluid. G. simplicifolia ...
Properties of diacylglycerol kinase in adult and fetal rat lung
(Elsevier, 1982-12-13)
Diacylglycerol kinase activity is found in both adult and fetal lung. Approximately 27 and 52% of the total activity is found in microsomes and cytosol, respectively. The activity is maximal at pH 7.4. The apparent Km for ...
Structure of a water-insoluble -glucan isolated from a streptococcal organism
(Elsevier, 1983-08-16)
The structure of the extracellular polysaccharide (water-insoluble -glucan) from an anaerobic, Gram-positive coccus organism (Streptococcus) has been investigated. Acid hydrolysis of the methylated glucan yielded 2,3,4,6-tetra-, ...
Evidence for a regulatory role of CTP : Choline phosphate cytidylyltransferase in the synthesis of phosphatidylcholine in fetal lung following premature birth
(Elsevier, 1981-07-24)
The sequence of reactions which function to incorporate choline into phosphatidylcholine was investigated in lung from fetuses following premature delivery. The rate of [methyl-14C]choline incorporation by rat lung slices ...
The content of diacylglycerol, triacylglycerol and monoacylglycerol and a comparison of the structural and metabolic heterogeneity of diacylglycerols and phosphatidylcholine during rat lung development
(Elsevier, 1981-04-23)
The content of diacylglycerol in fetal rat lung is approx. 36% of the adult and rapidly increases to adult levels by 1 day after birth. Triacylglycerol content is also low (23%) and increases to adult levels between 1 and ...
Increased synthesis of phosphatidylcholine by rat lung following premature birth
(Elsevier, 1980-01-18)
Pregnant rats were delivered prematurely at 20 days and 21 days gestation (2 and 1 day premature). The survival was 52 +/- 3% at 20 days gestation and 100% at 21 days gestation. [Me-14C]Choline incorporation into ...
Simple, rapid, and highly efficient separation of amino acid phenylthiohydantoins by reversed-phase high-performance liquid chromatography
(Elsevier, 1982-04)
A rapid and efficient separation of amino acid phenylthiohydantoins by high-performance liquid chromatography has been accomplished by step-gradient elution with use of a mobile phase of acetate-buffered aqueous acetonitrile ...
