An alternative electrophoretic method that improves the separation, identification and relative quantification of bovine milk casein fractions and casein hydrolysates was developed. The method is based in the Tricine-SDS-PAGE technique while the relative quantification of milk proteins has been achieved by digital densitometry. The advantages of this procedure for milk proteins and milk protein...
We describe buffer for both immunoelectrophoresis and zone electrophoresis procedures in agarose gels, Tricine [N-tris(hydroxymethyl)methylglycine] and Tris [2-amino-2-(hydroxymethyl)-1,3-propanediol] being the main components. This buffer eliminates the procurement cost and inventory control associated with formulation of barbital buffers. We compare it with other common buffer formulations.
Dunaliella tertiolecta required carbon dioxide in substrate concentrations (1.75 %, v/v) to assimilate either nitrate or nitrite at maximum rates in light. The addition of glucose, glycerol, acetate, pyruvate or a-ketoglutarate did not remove the requirement for carbon dioxide. The rates of nitrate and nitrite assimilation in light depended upon the buffer system used. The lowest rates of nitra...
We describe a microfluidic Western blot assay (μWestern) using a Tris tricine discontinuous buffer system suitable for analyses of a wide molecular mass range (6.5-116 kDa). The Tris tricine μWestern is completed in an enclosed, straight glass microfluidic channel housing a photopatterned polyacrylamide gel that incorporates a photoactive benzophenone methacrylamide monomer. Upon brief ultravio...
Background: UBI 29-41 (a derivative of antimicrobial peptide ubiquicidin) labelled with 99mTc is reported to discriminate between bacterial infections and sterile inflammatory processes. In this study, three lyophilized kit were performed, one of them based on the direct labelling with only SnCl2 as reducing agent , and other two based on 6- hydrazinopyridine-3-carboxylic acid (HYNIC) and trici...
The scorpion Iurus dufoureius asiaticus (Birula 1903) which is the largest scorpion in Europe and Turkey belongs to the family Iuridae and is endemic in Turkey. No data has been found about the venom components of I. d. asiaticus. In this study, the venom extract ob-tained from I. d. asiaticus specimens collected from Aydin were analyzed using the Tris tricine SDS-PAGE method. A total of 28 pro...
The use of a nonvolatile buffer system is advantageous for pH control in animal cell cultures because it not only eliminates the necessity for a constant carbon dioxide environment but also facilitates the manipulations of cell populations during growth, maintenance, and experimentation without the concomitant fluctuations in pH of the medium . In 1966, Good et al . (1) described the preparatio...
Hydrazinonicotinamide (HYNIC) is an established bifunctional complexing agent for technetium-99m ((99m)Tc) but the structure of the technetium coordination sphere remains uncertain. To gain further insight into this, we have prepared conjugates of HYNIC and hydrazinobenzoic acid (HYBA) with a model peptide, and radiolabelled them with (99m)Tc using three well-established co-ligand systems: EDDA...
Many excitatory synapses contain high levels of mobile zinc within glutamatergic vesicles. Although synaptic zinc and glutamate are coreleased, it is controversial whether zinc diffuses away from the release site or whether it remains bound to presynaptic membranes or proteins after its release. To study zinc transmission and quantify zinc levels, we required a high-affinity rapid zinc chelator...
