In this research, a PVC membrane electrode for Manganese (II) ions based on N-(2-Picolinamidoethyl)Picolinamide as neutral carrier was prepared. The electrode exhibits a Nemstian responseover Mn(II) concentration range of (1.0 x10-5 t01.0 X 10-1M) with a slope of 29.3±0.5 mV perdecade of concentration with a working pH range of 4.0-9.0. It has a fast response time (
Here, a simple, quick, Low cost and sensitive Potentiometric method is described for tramadol hydrochloride measurement using .PVC membrane electrode based on neutral ligand (E)-N'-(1-(2-hydroxyphenyl)ethylidene)benzohydrazid. Besides, effect of various parameters like ionic additives, membrane solvent and pH on the Potentiometric response of the electrode are investigated. The best electrode p...
Although signals for vacuolar sorting of soluble proteins are well described, we have yet to learn how the plant vacuolar sorting receptor BP80 reaches its correct destination and recycles. To shed light on receptor targeting, we used an in vivo competition assay in which a truncated receptor (green fluorescent protein-BP80) specifically competes with sorting machinery and causes hypersecretion...
Membrane traffic in eukaryotic cells relies on recognition between v-SNAREs on transport vesicles and t-SNAREs on target membranes. Here we report the identification of AtVTI1a and AtVTI1b, two Arabidopsis homologues of the yeast v-SNARE Vti1p, which is required for multiple transport steps in yeast. AtVTI1a and AtVTI1b share 60% amino acid identity with one another and are 32 and 30% identical...

This study addressed whether phosphorylation regulates trafficking of yeast membrane proteins that cycle between the trans-Golgi network (TGN) and endosomal system. The TGN membrane proteins A-ALP, a model protein containing the Ste13p cytosolic domain fused to alkaline phosphatase (ALP), and Kex2p were found to be phosphorylated in vivo. Mutation of the S13 residue on the cytosolic domain of A...
In this paper, the synthesis of a novel ionophore, chloro[5,10,15,20-tetrakis[2-(2,3,4,6-tetraacetyl-beta-D-glucopyranosyl)-1-O-phenyl]porphinato]manganese (MnT(o-glu)PPCl), and its application as a neutral carrier for a PVC membrane electrode are described. The MnT(o-glu)PPCl-based PVC membrane electrode shows a potentiometric responses to SCN- over a concentration range of 3.4 x 10(-7) - 1.0 ...
The construction and electrochemical response characteristics of a poly(vinyl chloride) (PVC) membrane selective electrode for the determination of tiapride (TPD) are described. The sensing membrane comprised an ion-pair formed between the protonated drug and tetraphenylborate (TPB) in a plasticized PVC matrix. The influence of membrane composition on the electrode response was studied. The ele...
