Donkey Anti-Goat IgG (H+L) ATTO390
Antibody produced in donkey, affinity purified
Cat. #: 2901-1MG
Applications
Suited for fluorescence microscopy and other sensitive fluorescence-based applications. The preservative-free formulation minimizes interference in demanding assay conditions.
Description
| Product name | Donkey Anti-Goat IgG (H+L) ATTO390 | DXG ATTO390 |
| Target species | Goat |
| Description |
ATTO-labeled secondary antibodies combine high fluorescence intensity with strong photostability and reliable performance in fluorescence-based detection. Donkey Anti-Goat IgG (H+L) ATTO390 is designed for the detection of goat primary antibodies and is suitable for fluorescence microscopy and related applications. The antibody is supplied without preservatives. After conjugation, free dye is removed by gel filtration to minimize background fluorescence and support reproducible staining performance. |
| Specification | Immunofluorescence: 1:500–1:1500, Degree of Labeling (DOL): 2–5, Unbound dye ≤5% of total fluorescence. |
| Optical properties | λabs: 390 nm, λfl: 476 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) ATTO390 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 ATTO390, 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.
