The capacities of Procion Red HE-3B and Cibacron Blue F3G-A immobilized to Sepharose CL-4B and Matrex 201R for NAD+-, NADP+- and NAD(P)+-dependent dehydrogenases were measured. Procion Red HE-3B columns retarded NADP+-dependent dehydrogenases more effectively than NAD+-dependent dehydrogenases, whilst immobilized Cibacron Blue F3G-A retarded NAD+-dependent dehydrogenases more effectively than N...

Human platelets were tested for the presence of proteins immunologically cross-reactive with red cell spectrin and protein 4.1. As assessed by indirect immunofluorescence microscopy, platelets were specifically reactive with affinity-purified rabbit antisera against red cell spectrin and protein 4.1. The immunoreactive platelet constituents were further analyzed by sodium dodecyl sulfate-polyac...

Reactive Red 120 was utilized as an affinity dye-ligand to modify the surface of magnetic chitosan microspheres to improve the adsorption capacity for lysozyme. The impact of pH, ionic strength, adsorption time and initial lysozyme concentration on the adsorption of lysozyme from aqueous solutions was investigated. An increased adsorption amount of 116.9 mg/g lysozyme on Reactive Red 120 modifi...

The contribution of the metabolic state of human erythrocytes to maintenance of cellular deformability was studied during and after in vitro incubation in serum for periods up to 28 hr. An initial loss of membrane deformability became apparent between 4 and 6 hr when cellular adenosine triphosphate (ATP) levels were approximately 70% of initial values. Membrane deformability then remained stabl...

Abstract In the present work, we have synthesized GdVO 4 doped Eu 3+ using a facile sol-gel method and analysed effect of concentration variation annealing temperature on optical properties. Tetragonal (I4 1 /amd) zircon type crystal structure material was confirmed by x-ray diffraction (XRD) study. The photoluminescence (PL) spectra were recorded with an ultraviolet (UV) excitation wavelength ...

Red-light irradiation of etiolated wheat (Triticum aestivum L.) leaf protoplasts rapidly increases calcium-dependent phosphorylation in vivo of 70- and 60-kD peptides, and the phosphorylation is attenuated by simultaneous far-red light (K.M. Fallon, P.S. Shacklock, A.J. Trewavas [1993] Plant Physiology 101:1039-1045). When these protoplasts were solubilized in sodium dodecyl sulfate and protein...

We report here the formation of plasmid linear multimers promoted by the Red-system of phage lambda using a multicopy plasmid comprised of lambda red alpha and red beta genes, under the control of the lambda cI857 repressor. Our observations have revealed that the multimerization of plasmid DNA is dependent on the red beta and recA genes, suggesting a concerted role for these functions in the f...
