Alexa Fluor® Dye equivalents
Same as Alexa Fluor dyes, with multiple conjugation chemistry options, broad spectral selection, high photo-stability and signal intensity. These can be used for fluorescent labeling of antibodies, peptides, proteins, tracers, and amplification substrates for various applications

AQuora® Dyes

Bright, hydrophilic, water-soluble dyes
Conjugated with PEG spacers to increase solubility, decrease non specific binding and enable a very high degree of labeling (DOL) for complex applications such as super resolution microscopy or fluorescent labeling of low abundance targets.

Cyanine Dyes

- Photostable, bright hydrophilic dyes with various reactive groups ideal for labelling protien, peptides and oligonucleotides
- Available in sulfonated & non-sulfonated cyanines

Tamra Dyes

'- Fluorescent dye commonly used to modify / label oligos for FRET and Real Time PCR applications
- Available in formats that enable Cu-catalyzed or Cu-free click chemistry

MB Dyes

'-Bright hydrophillic dyes less susceptiple to self quenching
- Versatile dye used in various reasearch and medical application

IR Dyes

'-Photostable dyes widely used in real time imaging and tracing applications
- Available with various reactive groups that allows tagging of a variety of biomoclues

Cal Fluor dyes

'- Fluorogenic azide probes that are activated by Cu-catalyzed or metal-free click chemistry
- Enable sensitive biomolecule detection under no-wash conditions for applications that require sensitive visualizations of matabolically labelled molecules

Other Florescent Dyes & Quenchers (Replacing Classic Fluorescent dyes)

'-Fluorescent dyes & Quenchers with well documented properties in many methodologies
- MB 800z - A novel class of sterically shielded NIR dyes that are used in diagnostic and imaging applications that require high sensitivity and photostability
