Alexa Fluor 647 Conjugated Antibodies

Alexa Fluor® 647 dyes, part of our Alexa Fluor fluorescent conjugates range, give you a superior far-red fluorophore that is commonly used in flow cytometry and immunofluorescence / confocal microscopy applications.

Mouse peritoneal macrophages dual stained with F4/80 antibody FITC

Fig. 1. Dot Blot showing FSC/SSC gated mouse peritoneal macrophages dual stained with F4/80 antibody, FITC (MCA497F) at a 1/5 dilution and CD11b antibody (MCA74A647) at a 1/5 dilution. Isotype control pair in red. Fc receptors were blocked by mouse Seroblock (BUF041B).

Sometimes referred to as AF647, Alexa Fluor 647 dyes are:

  • Bright and stable
  • Excited by a helium-neon laser or a red diode laser
  • Usually detected in the same fluorescence channel as Cy5
  • Alternative for Cy5 conjugates
  • Brighter and more photostable than Cy5

Antibodies Conjugated to Alexa Fluor 647

Bio-Rad offers primary antibodies conjugated to Alexa Fluor 647 across human, hamster, mouse, and rat catalog ranges.

Alexa Fluor 647 dye molecules have the ability to bind to proteins in high molar ratios without considerable self-quenching. This results in the formation of more radiant conjugates and improved detection sensitivity. Due to these properties, it is an outstanding option for the highly sensitive detection of biological structures that are present in low quantities.
