Alexa Fluor ® Conjugates

Alexa Fluor® fluorescent conjugates give you outstanding results in flow cytometry and immunofluorescence / confocal microscopy. Alexa Fluor® conjugates are:

• Brighter and more fluorescent than comparable spectral conjugates
• More photostable than other fluorochromes
• Insensitive to changes in pH over a broad range
• Ideal for multicolor applications due to minimal spectral overlap
• Compatible with all common fluorescence detection channels

Key Alexa Fluor® Conjugates

Four of the most useful Alexa Fluor® conjugates: 405, 488, 647 and 700 are widely available across our human, mouse, and rat product catalog ranges.

Technical Features of Alexa Fluor® Conjugates

Alexa Fluor® 405

• The best blue fluorochrome available
• Potentially more intense in fluorescence than other UV light-excitable blue conjugates
• Excited by Blue Diode, Violet, or Krypton lasers
• Usually detected in the same fluorescence channel as Cascade Blue
• Minimal overlap with green fluorophores

Alexa Fluor® 488

• The finest green fluorophore available
• Excited by an Argon-Ion laser
• Usually detected in the same fluorescence channel as FITC
• Alternative for fluorescein conjugates (FITC, FAM) and Cy2
• Brighter and more photostable than fluorescein

Alexa Fluor® 647

• A very high quality red/purple dye
• Replaces APC (allophycocyanin) or Cy5
• Excited by Helium-Neon or Krypton-Neon lasers
• Usually detected in the same fluorescence channel as APC
• Total fluorescence significantly higher than Cy5 dyes
• More photostable than DPXL-3, Cy5, and APC conjugates

Alexa Fluor® 700

• A near infrared dye
• Excited by xenon-arc lamp, far red diode lasers or dye-pumped lasers (675-700 nm)
• Usually detected in the same fluorescence channel as APC
• Brighter than Cy5, Cy5.5, Cy7, and similar dyes
• More photostable than Cy5 and APC conjugates
