General description

3,3′-Dipropylthiacarbocyanine iodide is a carbocyanine fluorescent dye sensitive to membrane potential. This cyanine dye plays a vital role as an optical probe of membrane potential. An increase in the fluorescence intensity of the dye indicates depolarization of the plasma membrane potential.

Application

3,3′-Dipropylthiacarbocyanine iodide has been used to determine bacterial membrane permeability by the effect of electrochemical scaffold treatment.

Biochem/physiol Actions

The embrane potential sensitive dye, 3,3′dipropylthiacarbocyanine iodide enters only depolarized cells, where it binds reversibly to lipid-rich intracellular components.

Conventional role of ribosomal proteins is ribosome assembly and protein translation, but some ribosomal proteins also show antimicrobial peptide (AMP) activity, though their mode of action remains ill-defined. Here we demonstrated for the first time that amphioxus RPS15, BjRPS15, was

The ever-growing concerns on multi-drug resistant (MDR) bacteria lead to urgent demands for novel antibiotics including antimicrobial peptides (AMPs). Pt5, a peptide consisting of the C-terminal 55 residues of zebrafish phosvitin, has been shown to function as an antibacterial agent.

Previous studies show that some ribosomal proteins possess antimicrobial peptide (AMP) activity. However, information as such remains rather fragmentary and rather limited. We showed here for the first time that amphioxus RPS23, BjRPS23, was a previously uncharacterized AMP. It not

Mitochondrial permeability transition pore (PTP) is supposed to at least in part participate in molecular mechanisms underlying the neurotoxicity seen after overactivation of N-methyl-D-aspartate (NMDA) receptor (NMDAR) in neurons. In this study, we have evaluated whether activation of GABA
