Texas Red alkyne deuterium-labeled-carboxylic ester 393 SMILES OCCCCCCOC1=C2C(=O)N(C3CCC(=O)NC3=O)C(=O)C2=CC=C1 Purity (HPLC)Sulforhodamine 101 alkyne (Texes Red alkyne) is an excellent azide reactive fluorescent reagent for labeling azide containing biological molecules through click chemistry. The conjugate has better solubility than the parent dye carboxyrhodamine and its long PEG spacer should reduce any steric effect of the dye on the molecule to be labelled. Sulforhodamine 101 emits at a longer wavelength than does either Tetramethylrhodamine or Sulforhodamine B. With
