Description
Description: Although Texas Red® is the most popular labeling reagent of sulfonyl chloride, it is quite unstable in water. Even in anhydrous DMF, Texas Red® tends to give a very complicated reaction mixture. It reacts with thiols, alcohols, phenols, aliphatic amines and aromatic amines indiscriminatingly. California Red™ is a succinimidyl ester and has the spectral properties identical to those of Texas Red®. California Red™ is a superior replacement for Texas Red®. California Red™ only reacts with aliphatic amines such as amino acids, peptides and proteins to give bright red fluorescent conjugates that are extremely stable. Compared to Texas Red, California Red has much higher labeling efficiency, and more importantly the resulted conjugates are much easier to be purified due to its much cleaner reactions. We strongly recommend that you consider using California Red™ to replace Texas Red® for labeling peptides and oligonucleotides.
