Carbotrace 540

Carbotrace 540 is our yellow optotracer for labeling repetitive motifs in proteins and carbohydrates. Generally, Carbotrace labeling is strongest with protein aggregates. Homoglucans like cellulose are labeled reliably, albeit with lower quantum yield. Heteroglucans with low degree of branching like starches are labeled and can be distingiushed by their spectral fingerpint. Generally labelling of hemicelluloses is weak or absent.

Specifically, Carbotrace 540 has been used to determine the purity of cellulose extracted from macroalgae by allowing analysis of extracted carbohydrates in their polymeric state. In addition, Carbotrace 540 has shown to bind to the hemicellulose xyloglucan. Contact us to learn more about applications for Carbotrace 540.

Carbotrace 540 is available in three different formulations (See volumes and prices in the drop-down list below): 

• Aqueous: 1 mg/ml solution in ultrapure water. The product should be diluted 1:1000 before use. To prevent evaporation of the aqueous solvent, close the container carefully after use, spin down liquid and use up small volumes quickly.
• DMSO: 1 mg/ml solution in DMSO to prevent solvent evaporation. The product should be diluted 1:1000 before use. For use in live-cells, sometimes 1:500 is necessary due to uptake limitations.
• Drop&Shine: 5 ml ready-to-use product in mounting medium. Ideal for use in tissue sections. Add a some Drop&Shine and mount your slide to detect biofilms within minutes.
