Suited for 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) ATTO740 | GXR ATTO740
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) ATTO740 is designed for the detection of rabbit primary antibodies and is suitable for fluorescence microscopy, flow cytometry and related fluorescence-based applications.
ATTO740 has an absorption maximum at 743 nm and a fluorescence maximum at 763 nm. Its spectral properties place it in the near-infrared range and support fluorescence detection with excitation near 740 nm.
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
λabs: 743 nm, λfl: 763 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) ATTO740
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 ATTO740, 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.
