Tex Red-X dye is an innovative alternative to Tex Red. A key difference lies in its chemical structure - it features an additional seven - atom aminocaproyl spacer ("X") between the fluorophore and the carboxyl group. This spacer plays a crucial role in separating the fluorophore from its attachment point. By doing so, it effectively minimizes the interaction between the fluorophore and the conjugated biomolecule. One of the standout features of Tex Red - X is that it exists as a single 5 - isomer. This characteristic significantly enhances the reproducibility of results, which is a highly desirable trait in scientific research and biological applications. In terms of optical properties, Tex Red - X shares the same spectral characteristics as Texas Red. It can be utilized to create bright red fluorescent bioconjugates with excitation and emission maxima at approximately 595/615 nm. These bioconjugates are valuable tools in various biological and biochemical studies, enabling researchers to visualize and analyze biological processes with high precision.

Providing storage is as stated on the product vial and the vial is kept tightly sealed, the product can be stored for up to 24 months.
Wherever possible, you should prepare and use solutions on the same day. However, if you need to make up stock solutions in advance, we recommend that you store the solution as aliquots in tightly sealed vials at -20°C. Generally, these will be useable for up to one month. Before use, and prior to opening the vial we recommend that you allow your product to equilibrate to room temperature for at least 1 hour.
