Suited for high-sensitivity fluorescence microscopy, flow cytometry and other fluorescence-based applications. The preservative-free formulation minimizes interference in sensitive assay conditions.
Description
Product name
Goat Anti-Rabbit IgG (H+L) ATTO488 | GXR ATTO488
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) ATTO488 is designed for the detection of rabbit primary antibodies and is suitable for fluorescence microscopy, flow cytometry and related fluorescence-based applications.
ATTO488 has an excitation maximum at 501 nm and an emission maximum at 523 nm, producing bright green fluorescence. Its spectral properties are well suited to commonly available 488 nm excitation sources and standard green fluorescence detection channels.
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: 501 nm, λem: 523 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) ATTO488
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 ATTO488, 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.
