Donkey Anti-Goat IgG (H+L) ATTO565
Antibody produced in donkey, affinity purified
Cat. #: 2908-1MG
Applications
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) ATTO565 | DXG ATTO565 |
| 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) ATTO565 specifically detects goat primary antibodies and is suitable for widefield, confocal and TIRF microscopy, flow cytometry, single-molecule detection and super-resolution imaging, including PALM, dSTORM and STED. ATTO565 has an absorption maximum at 563 nm and a fluorescence maximum at 592 nm. The conjugate is excited efficiently within the 545–575 nm spectral range and is well matched to the widely available 561 nm laser line. Its strong absorption, high fluorescence output and pronounced photostability support sensitive detection, repeated scanning and prolonged image acquisition. ATTO565 is particularly suitable for demanding high-resolution and single-molecule fluorescence applications. Donkey Anti-Goat IgG (H+L) ATTO565 is antigen-specific; affinity purification removes essentially all donkey serum proteins, including immunoglobulins not specifically binding to goat IgG. Following conjugation to ATTO565, 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. |
| Specification | Immunofluorescence: 1:500–1:1500, Degree of Labeling (DOL): 2–5, Unbound dye ≤5% of total fluorescence. |
| Optical properties | λabs: 563 nm, λfl: 592 nm |
Properties
| Form | Lyophilized |
| Nominal concentration | 2 mg/ml (after reconstitution with buffer) The antibody is supplied as 1.0 mg lyophilized powder and shipped at ambient temperature. A glycerol buffer is included for reconstitution to 2 mg/ml. After reconstitution, the glycerol stock may be stored at -20°C without freezing. Avoid repeated freeze/thaw cycles. |
| Content | 1.0 mg Donkey Anti-Goat IgG (H+L) ATTO565 1.0 ml Glycerol buffer (add 0.5 ml to reconstitute the lyophilized antibody) Buffer: 50% glycerol, 0.01 M sodium phosphate, 0.1 M sodium chloride, pH 7.4 |
| Clonality | Polyclonal |
| Isotype | IgG |
| Purification notes | Affinity purification removed donkey serum proteins and immunoglobulins not specifically binding to goat IgG. Following conjugation to ATTO565, 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. |
| Remarks | For research use only. Not for diagnostic, therapeutic, clinical or in vivo use. |
Buffers and antibodies from Hypermol® are made of the purest reagents in Milli-Q™ water, as described in our publications.
