Alexa Fluor™ 647 streptavidin comprises a biotin-binding protein (streptavidin) covalently attached to a fluorescent label (Alexa Fluor™ dye).
Streptavidin Invitrogen™
A bacterially derived biotin-binding protein that reportedly exhibits less nonspecific binding than avidin.
HRP-Conjugated Streptavidin Thermo Scientific™
Streptavidin from Streptomyces avidinii conjugated to highly purified horseradish peroxidase (HRP)
Alexa Fluor™ 488 streptavidin comprises a biotin-binding protein (streptavidin) covalently attached to a fluorescent label (Alexa Fluor™ dye).
Streptavidin, Alexa Fluor™ 700 conjugate
Streptavidin - HRP Invitrogen™
Streptavidin - HRP
Commonly used in indirect staining protocols to detect biotinylated primary antibodies in flow cytometry. Streptavidin binds to biotin with high affinity.
Pierce™ Biotin Thermo Scientific™
Thermo Scientific™ Pierce Biotinylated Proteins include biotin-labeled horseradish peroxidase (B-HRP), alkaline phosphatase (B-AP) and fluorescein (B-FITC) for use as controls or signal amplification in IHC via avidin-biotin complex (ABC) techniques.

Streptavidin-based amplification techniques are widely used in flow cytometry, fluorescent imaging, western blotting, and microplate-based detection for increased signal output and greater sensitivity.
Invitrogen eFluor 660 dye is a red-fluorescent dye configured as an alternative to Alexa Fluor 647 or APC. The spectral properties make it an ideal fluorophore that can be used in any flow cytometry panel incorporating the red laser.
