產品說明：
Although sulforhodamine 101 acid chloride （also called Texas Red?） is the most popular labeling reagent of sulfonyl chloride, it is quite unstable in water, especially at the higher pH required for reaction with aliphatic amines. Texas Red （TR） reacts with both aliphatic amines and aromatic amines indiscriminatingly. In addition, the labeling efficiency of Texas Red is extremely low compared to dye succinimidyl esters. California Red? SE is a succinimidyl ester. It is an excellent replacement for Texas Red. California Red （CR） reacts with amine compounds 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 conjugate is more fluorescent than the corresponding Texas Red conjugate. The conjugates of California Red have the identical excitation and emission wavelengths to those of Texas Red. Our in-house studies indicated that California Red is more stable than Texas Red under the same labeling conditions.
