Dextran, Cy5 Labeled

Product Overview

Description

Dextrans are hydrophilic polysaccharides characterized by their moderate-to-high molecular weight (3-200 kD). These molecules can exist in either charged or uncharged forms depending on the conjugated fluorophore. Due to their low immunogenic properties, dextrans are often used as effective tracers in various applications.
Cy5-labeled dextran is a near IR fluorescent dextran conjugate.

Q&As

What types of imaging techniques are compatible with this product?

Dextran, Cy5 Labeled is compatible with various imaging techniques, including fluorescence microscopy, confocal microscopy, and multi-photon microscopy. The Cy5 dye provides strong fluorescence in the far-red spectrum, which is well-suited for high-resolution imaging and deep tissue penetration, making it versatile for different microscopy applications.

Can Dextran, Cy5 Labeled be used to trace neuronal activity in addition to neural pathways?

It is primarily designed for tracing neural pathways rather than directly measuring neuronal activity. For tracing neural pathways, it allows visualization of the connectivity between neurons. However, it does not provide real-time information about neuronal activity. For activity measurements, other fluorescent indicators or biosensors would be more appropriate.

Are there any safety considerations when handling and using Dextran, Cy5 Labeled?

When handling Dextran, Cy5 Labeled, standard laboratory safety protocols should be followed. Wear appropriate personal protective equipment (PPE), such as gloves and lab coats, to avoid direct contact with the reagent. Ensure proper disposal of any waste materials according to your institution’s guidelines. Additionally, avoid prolonged exposure to light to prevent degradation of the Cy5 dye.
