Rox Passive Reference dye, 10 ml bottle

Dde TAMRA Biotin Azide is a trifunctional, cleavable probe that allows for efficient recovery of avidin-bound protein complexes in affinity-based assays. This reagent contains a fluorescent dye (TAMRA) and biotin moiety linked to azide group through a spacer arm containing a hydrazine-cleavable Dde moiety. Under mild conditions (2% aqueous hydrazine), the Dde liner is cleaved, releasing the biotin tag and any avidin conjugate bound to it. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

BP Fluor 488 NHS ester is a powerful labeling dye. It will react with the amine group in antibody, proteins, peptides, amino-modified oligos, and other target molecules. The dye has an excitation peak at 499 nm and an emission peak at 520 nm. The conjugates are widely used in microscopy, flow cytometry, and other applications. BP Fluor 488 is a pure 5- sulfonated rhodamine molecule and it eliminates the lot-to-lot variation caused by two isomers ratio differences.
