Pet fluorophore

The probes employed in PET–fluorescence imaging incorporate both a fluorophore and radioisotope which enable complementary information to be obtained from both imaging techniques via the administration of a single agent. In this study, the zwitterionic NIR fluorophore ATTO655, which has good fluorescence quantum yield and excellent photostability, was used to synthesize Q‐annexin V as the dye showed high fluorescence quenching efficacy by amino acid quenchers (tryptophan and tyrosine) and is considered an excellent PET‐based fluorescence sensor for assessing small conformational changes in proteins. A variety of fluorophores from the rhodamine family are offered that range from green (Rhodamine Green, Em 531 nm) through red (ROX, Em 608 nm) emission. Compared to the fluorescein family of dyes, rhodamine dyes are relatively resistant to photobleaching and can be used over a wider pH range.

Fluorophore Selection Overview R-phycoerythrin (R-PE) is an intensely bright phycobiliprotein isolated from red algae that exhibits extremely bright red-orange fluorescence with high quantum yields. It is excited by laser lines from 488 to 561 nm, with absorbance maxima at 496, 546, and 565 nm and a fluorescence emission peak at 578 nm.

Photoinduced electron transfer (PET) between organic fluorophores and suitable electron donating moieties, for example, the amino acid tryptophan or the nucleobase guanine, can quench fluorescence upon van der Waals contact and thus report on molecular contact.

Based on molecular complexity and synthetic methods, fluorophore molecules could be generally classified into four categories: proteins and peptides, small organic compounds, synthetic oligomers and polymers, and multi-component systems. Fluorescence probes are superior to PET probes in terms of temporal stability.

Case in point: flow cytometry. Once a tool only used by “real” immunologists, flow cytometry is fast becoming a method by which numerous questions can be answered, from the length of a cell’s telomeres, to the state of metabolism of a cell.

PET is a deactivation process involving an internal red-ox reaction between the excited state of the fluorophore and another species able to donate or to accept an electron. A fundamental point explaining this process is to consider that in the excited state the properties of the species are quite different compared with those of the ground-state.

Polytetrafluoroethylene (PTFE) membrane filters, with their broad chemical compatibility, are versatile filters for general clarification. Choose Fluoropore™ Hydrophobic PTFE Membrane Filters for filtering organic-based liquids or gases, and choose and Omnipore™ Hydrophilic PTFE Membrane Filters for filtering aqueous solutions.

We have focused our research mainly on developing fluorescent photoinduced electron transfer (PET) sensors based on the fluorophore-spacer-anion receptor principle using several anthracene (emitting in the blue) and 1,8-naphthalimide (emitting in the green) fluorophores, with the aim of targeting biologically and industrially relevant anions such as acetates, phosphate and amino acids, as well as halides such as fluoride. PET is a deactivation process involving an internal red-ox reaction between the excited state of the fluorophore and another species able to donate or to accept an electron.
