Dextran, NHS Activated

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.

Q&As

What methods are recommended for conjugating Dextran, NHS Activated with fluorescent dyes or proteins?

To conjugate Dextran, NHS Activated with fluorescent dyes or proteins, follow a standard NHS-ester coupling protocol. Mix the Dextran with the dye or protein in a suitable buffer, typically under mild conditions to avoid degradation. It's important to optimize the reaction conditions, such as pH and temperature, to ensure efficient conjugation and minimal byproducts.

How stable is Dextran, NHS Activated once it is conjugated with a fluorescent dye?

Once conjugated, Dextran, NHS Activated generally exhibits good stability, provided that it is stored and handled correctly. The conjugated product should be stored at recommended temperatures, protected from light, and used within the suggested time frame to ensure optimal performance. Stability can also be affected by the specific dye or protein used, so it's important to consult specific protocols for each conjugation.

Are there any specific storage requirements for Dextran, NHS Activated to maintain its efficacy?

Dextran, NHS Activated should be stored according to the recommendations, typically in a cool, dry place, and protected from light. It is often advisable to store it at -20°C or lower to maintain its stability. Avoid repeated freeze-thaw cycles, as they can affect the integrity of the tracer. Always consult the product's datasheet for detailed storage instructions.
