Description
Product name
Goat Anti-Rabbit IgG (H+L) ATTO390 | GXR ATTO390
Target species
Rabbit
Description
ATTO-labeled secondary antibodies combine high fluorescence intensity with strong photostability and reliable performance in fluorescence-based detection. Goat Anti-Rabbit IgG (H+L) ATTO390 is designed for the detection of rabbit primary antibodies and is suitable for fluorescence microscopy and related applications.
ATTO390 has an excitation maximum at 390 nm and an emission maximum at 476 nm. Its large Stokes shift of 86 nm provides clear separation between excitation and emission, which can facilitate spectral discrimination in multicolor experiments.
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): 2-9, Unbound dye ≤5% of total fluorescence.
Optical properties
λex: 390 nm, λem: 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 Goat Anti-Rabbit 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 goat serum proteins and immunoglobulins not specifically binding to rabbit 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.
