Bio-Synthesis offers DyLight™ 755 fluorescent dye oligonucleotide labeling services.  DyLight™ 755  is a near infradred (IR) dye. It has spectral properties that are similar to other near-IR dyes such as Alexa 750.

DyLight™ 755 dye can be incorporated at any position within an Oligonucleotide. A primary amine modified oligonucleotide is used to covalently attach with dye via NHS conjugation chemistry; other cross-linking chemistries are also available depending on particular project specifications. Dual HPLC purification follow by additional step of ultrafiltration is used to remove failure sequences during first HPLC purification,  after labeling, the second HPLC is performed to remove unlabeled oligonucleotides and excessive dye in order to obtain a full length labeled oligonucleotide.
