BOC Sciences offers biotin, thiol, and other functional group-bound rhodamine PEG derivatives, providing a powerful tool for researchers and clinicians to study and manipulate biological systems.

Examples of Rhodamine PEG

Rhodamine-PEG-Thiol

The thiol functional group of Rhodamine-PEG-Thiol can react with other molecules through disulfide bond formation, making it an ideal tool for developing drug delivery systems. Rhodamine-PEG-Thiol is used to couple a wide range of therapeutic agents, including proteins, peptides and small molecules, thereby improving drug stability, solubility and bioavailability.

Rhodamine-PEG-Biotin

Rhodamine-PEG-Biotin is a small molecule compound consisting of several functional groups. The rhodamine moiety is a fluorescent dye commonly used in biomedical research and diagnostics to label and visualize specific molecules and cells. The biotin moiety is a small molecule typically used as a tag or label to bind to streptavidin or affinity proteins, which can then be used for various purposes, such as purification, detection or quantification.

Pyrene-PEG-Rhodamine

Pyrene-PEG-Rhodamine has pyrene and rhodamine at each end of the molecular chain and can be used to label proteins, antibodies, peptides, nucleic acids or particles. Pyrene-PEG-Rhodamine acts as a heterobifunctional PEG that can be attached to different molecules or materials to extend the richness of different molecular combinations.

Characteristics of Rhodamine PEG

Fluorescence

Rhodamine-PEG can absorb and emit light in the visible range. And the fluorescence property of rhodamine-PEG can be modulated by adjusting the structure of rhodamine dye and the length of PEG chain.

Targeting

Specific ligands or antibodies can be introduced into the PEG chain to enable rhodamine-PEG to bind to specific cells or tissues for targeted delivery and imaging. This targeting can improve the accuracy and specificity of imaging.

Stability

The presence of PEG improves the stability of rhodamine-PEG and enhances its resistance to light, enzymes and oxidation, prolonging its circulation time and duration of action in the organism.

Applications of Rhodamine PEG

Fluorescent labeling

Rhodamine-PEG has fluorescent properties and can be used as a fluorescent marker for cells and biomolecules. By binding rhodamine-PEG to a target molecule, it is possible to track and visualize it in the organism.

Bioimaging

Due to its strong fluorescent signal and long fluorescence lifetime, rhodamine-PEG can be used in bioimaging applications such as fluorescence microscopy to observe changes in internal cell structure and function.

Biosensing

Rhodamine-PEG can be used to construct biosensors for detecting the presence and concentration changes of biomolecules. By combining specific biorecognition molecules with rhodamine-PEG, highly sensitive and selective detection of target molecules can be realized.
