Anaspec has introduced a collection of Tetramethylrhodamine C2 maleimides that represent a cost-effective replacement for Tetramethylrhodamine maleimides.
While their spectral characteristics are very similar to those of Tetramethylrhodamine maleimides, Tetramethylrhodamine C2 maleimides are notably less expensive.
They can be used for thiol modification of proteins, antibodies and peptides.
