eBioscience™ Streptavidin eFluor™ 660 Conjugate Invitrogen™

The streptavidin fluorochrome conjugates are commonly used in indirect staining protocols to detect biotinylated primary antibodies in flow cytometry, immunohistochemistry, and immunocytochemistry applications. Streptavidin binds to biotin with high affinity.

eBioscience™ Streptavidin Super Bright 436 Conjugate Invitrogen™

eBioscience Streptavidin Super Bright 436 is a streptavidin-fluorochrome conjugate for indirect staining protocols to detect biotinylated primary antibodies in flow cytometry. Super Bright dyes are polymer-based fluorophores that are excited by the violet laser (405 nm) and emit fluorescence at the...

Alexa Fluor™ 488 Streptavidin, 10 nm colloidal gold conjugate Invitrogen™

Alexa Fluor® 488 streptavidin comprises a biotin-binding protein (streptavidin) covalently attached to a fluorescent label (Alexa Fluor® dye). Streptavidin has a very high binding affinity for biotin, and a conjugate of streptavidin is commonly used together with a conjugate of biotin for specific...

D-Biotin Invitrogen™

D-biotin binds with high affinity to streptavidin, avidin and NeutrAvidin® biotin-binding proteins.

R-Phycoerythrin, Biotin-XX Conjugate Invitrogen™

R-phycoerythrin biotin-XX conjugate consists of the exceptionally bright phycobiliprotein, R-PE conjugated with biotin-XX, where the biotin is well separated from the point of attachment by a fourteen-atom spacer.

MagniSort™ Streptavidin Negative Selection Beads Invitrogen™

MagniSort™ Streptavidin Negative Selection Beads are designed for the magnetic separation of cells by negative selection. Undesired cells are bound by a cocktail of biotinylated antibodies and then streptavidin coated magnetic beads.

Ultra Streptavidin-HRP Thermo Scientific™

Streptavidin-HRP consists of streptavidin protein that is covalently conjugated to horseradish peroxidase (HRP) enzyme. Streptavidin binds to biotin and the conjugated HRP provides a high level of activity for detection using an appropriate substrate system.

CaptAvidin™ Biotin-Binding Protein Invitrogen™

CaptAvidin™ biotin-binding protein contains a nitrated tyrosine in its biotin-binding site. This chemical modification permits dissociation of the avidin-biotin complex under milder conditions than the traditional avidin-biotin complex. At pH 4.

HRP-Conjugated Streptavidin Thermo Scientific™

HRP-Conjugated Streptavidin consists of streptavidin protein that is covalently conjugated to horseradish peroxidase (HRP) enzyme (RZ > 3.0). Streptavidin binds to biotin and the conjugated HRP provides enzyme activity for detection using an appropriate substrate system.

Qdot™ 605 ITK™ Streptavidin Conjugate Kit Invitrogen™

The Qdot® 605 ITK™ Streptavidin Conjugate Kit provides the Qdot® streptavidin conjugate as 250 µL of a 2 µM solution. Unlike the Qdot® streptavidin conjugates, the Qdot® ITK™ streptavidin conjugates have the streptavidin covalently attached to the inner amphiphilic coating without a PEG linker.
