Suited for fluorescence microscopy, flow cytometry and other fluorescence-based applications. The preservative-free formulation minimizes interference in sensitive assay conditions.
Description
Product name
Donkey Anti-Goat IgG (H+L) ATTO514 | DXG ATTO514
Target species
Goat
Description
ATTO-labeled secondary antibodies combine high fluorescence intensity with strong photostability and reliable performance in fluorescence-based immunodetection. Donkey Anti-Goat IgG (H+L) ATTO514 specifically detects goat primary antibodies and is suitable for widefield, confocal and total internal reflection fluorescence microscopy (TIRF), flow cytometry and related fluorescence-based applications.
ATTO514 has an absorption maximum at 511 nm and a fluorescence maximum at 532 nm, producing green fluorescence. The conjugate is efficiently excited in the 510–535 nm spectral range and is particularly well matched to the 514 nm argon-ion laser line. Its high fluorescence output and photostability support sensitive detection, repeated scanning and prolonged image acquisition.
ATTO514 is also suitable for single-molecule detection and advanced fluorescence imaging, including PALM, dSTORM and STED. Performance in these applications depends on labeling density, sample preparation, imaging buffer and instrument configuration.
Donkey Anti-Goat IgG (H+L) ATTO514 is antigen-specific; affinity purification removes essentially all donkey serum proteins, including immunoglobulins not specifically binding to goat IgG. Following conjugation to ATTO514, the antibody is further purified by gel filtration to remove unbound dye and support low-background, reproducible fluorescence staining. The product is supplied without preservatives.

Purification notes
Affinity purification removed donkey serum proteins and immunoglobulins not specifically binding to goat IgG. Following conjugation to ATTO514, the antibody was further purified by gel filtration to remove unconjugated dye and low-molecular-weight reaction components.
Hypermol® secondary antibodies are highly specific and purified to remove unbound dye, minimizing background signal.
Storage instructions
Store as glycerol stock at -20°C. Avoid repeated freeze/thaw cycles.
Shipping conditions
Shipped at ambient temperature.
