Plasma membrane anion transporters play Transmembrane transport of anionic fluorescent dyes by suspension-cultured plant cells. book roles in plant cell biology, especially in stomatal closure and nutrition. Notwithstanding, a lot is still unknown about the specific function of these transporters, their specific localization, or molecular nature.
Here the fundamental roles of anionic transport in plant cells are by: A series of fluorescent anion transporters consisting of a urea or thiourea group linked to a naphthalimide fluorophore have been synthesised and their anion transport properties studied.

You are experimenting with a variety of lipids to determine their efficacy for use as drug delivery system liposomes. The marine plathyhelminth Macrostomum lignano was recently isolated from Adriatic shore sediments where it experiences a wide variety of environmental challenges, ranging from hypoxia and reoxygenation, feeding on toxic algae, to exposure to anthropogenic contaminants.

Carbocyanine dyes, such as DiI and its derivatives, label cell membranes without appreciably affecting cell viability and can be used for long-term studies.
The dyes uniformly label neurons via lateral. Polarity sensitive dyes are powerful tools to characterize such lipid membrane order.
These dyes change their emission spectrum depending on the polarity of the environment which can be used to quantify the molecular ordering and to visualize lateral heterogeneity in membrane order of cellular membranes.

The regulation of passage through the membrane is due to selective membrane permeability - a characteristic of biological.

Increased depolarization results in additional influx of the anionic dye and an increase in fluorescence. Cajal bodies are found in the nuclei of plant and animal cells, and the number and size of Cajal bodies per cell are subject to change, depending on cell type and cell cycle (Gall, ; Ogg and Lamond, ).
Cajal bodies are very often located at the nucleolar periphery and even within nucleoli. Because of their hollow interior, transmembrane channels are capable of opening up pathways for ions across lipid membranes of living cells.
Here, we demonstrate ion conduction induced by a single DNA duplex that lacks a hollow central channel. Decorated with six porpyrin-tags, our duplex is designed to span lipid membranes.
