Cyanine5 DBCO (DBCO-Cy5) is a low-toxicity azide reactive probe (NIR fluorescent dye), for imaging azide-labeled biomolecules via a copper-free "click-through" reaction. Cyanine5 DBCO has no apparent cytotoxicity or animal toxicity and shows no damage to the physiological functions of cells other than the target cells (azide-labeled cells). Cyanine5 DBCO can be used to label and track cells in vitro and in vivo (Ex=635 nm, Em=650-700 nm).

Cys-shift probe-1 (compound 13) is a potent Cys-shift probe. Cys-shift probe-1 can improve the ion mobility of labeled peptides and be used in protein analysis.

CBG-549-QSY7 is a Dylight 549-labeled SNAP tag fluorescent probe (Ex/Em: 546 nm/580 nm), specially designed for non-washable fluorescence imaging applications. CBG-549-QSY7 employs an intramolecular FRET quenching mechanism: intramolecular fluorescence quenching occurs before binding to the SNAP tag, and upon binding, the quenching group is cleaved, releasing fluorescence. The background fluorescence of CBG-549-QSY7 is extremely low, and clear cell membrane images can be obtained after 5 minutes of incubation.

dTCOBG (dTCO-SNAP) is a SNAP-tag reactive benzylguanine (BG) analogue specifically designed for the specific labeling of immune cells. dTCOBG forms a stable thioether bond through the cysteine at the active site of SNAP-tag and O6-benzylguanine, resulting in a covalent linkage. dTCOBG demonstrates unique advantages in the labeling of macrophages derived from ER-HoxB8: it only labels SNAP-tag + macrophages, with no background signal in the control group. dTCOBG can be used for click chemistry labeling.

BG-Tetrazine (BG-Tz; SNAP-Tetrazine) is a SNAP tag substrate that contains a methyl tetrazine group. BG-Tetrazine can specifically covalently label the target protein of the intracellular SNAP-tag fusion. The tetrazine group it carries can rapidly and efficiently undergo a bioorthogonal reaction with functional groups such as trans cyclooctene (TCO), thereby enabling multiple labeling, functionalization or enrichment of proteins. BG-Tetrazine can be applied in click chemistry.

BG-PhN3 is a SNAP-tagged substrate containing an azide group. BG-PhN3 can be used in click chemistry.

BG-JF549 is a Xanthene-based fluorophore. BG-JF549 has a similar affinity for SNAP^C145A to BG-TMR.

BG-SS-SulfoCy5 (SNAP-SS-SulfoCy5) is a SulfoCy5-labeled SNAP tag fluorescent probe, linked by a disulfide bond. BG-SS-SulfoCy5 combines the specific recognition of SNAP-tag, the cleavability of disulfide bond, and the excellent optical properties of SulfoCy5. BG-SS-SulfoCy5 can be used for tracking the internalization of cell surface proteins and multiple labeling experiments.

SNAP-FAM is a FAM-labeled SNAP tag fluorescent probe, specifically designed for live-cell protein labeling and real-time imaging applications.
