Effects of ethylenic bond position upon acyltransferase activity with isomeric cis-octadecenoyl coenzyme a thiol esters
(Elsevier, 1969-04-29)
The specificity of the acyl-CoA:phospholipid acyltransferases has been studied using the 16 positional isomers of cis-octadecenoic acid. The results showed that the acyl-transferases acting at both the 1- and 2-positions ...
Evaluation of lipoprotein size–density distributions from sedimentation coefficient distributions obtained at several solvent densities. I. Theory
(Wiley Subscription Services, Inc., A Wiley Company, 1969-01)
A method is presented for the treatment of distribution functions obtained by ultra-centrifugal sedimentation velocity experiments on the plasma lipoproteins, so that adequate corrections can he made for the effects of ...
Autoradiography with acrylamide gel slab electrophoresis
(Elsevier, 1969-04)
A method for electrophoresis and autoradiography with a multisample gel slab system has been described. The method obviates slicing of the gel, retains the high degree of resolution of bands in the autoradiogram, and enables ...
Photosynthetic membrane development in Rhodopseudomonas spheroides: Incorporation of bacteriochlorophyll and development of energy transfer and photochemical activity
(Elsevier, 1969-10-21)
1. 1. Bleached cells of Rhodopseudomonas spheroides, obtained by aerobic growth in the light, rapidly synthesize bacteriochlororphyll and carotenoids when transferred to 4% oxygen in the dark. Fluorescence excitation spectra ...
Semipermeable ion-exchange membranes as a preconcentration matrix for trace analysis by electrochemical and neutron-activation techniques
(Elsevier, 1969-01)
Ion-exchange membranes were used in conjunction with neutron-activation analysis and anodic stripping voltammetry for the determination of certain trace metal ions. The various parameters which govern the applicability, ...
