Optimized for super-resolution microscopy, confocal imaging, and flow cytometry, containing no preservatives for compatibility with sensitive applications.
ATTO-labeled secondary antibodies represent a gold standard in fluorescence labeling, renowned for their exceptional brightness, superior photostability, and consistent performance across diverse applications. Goat Anti-Guinea Pig IgG ATTO647N is specifically optimized for high-resolution imaging and advanced fluorescence techniques.
The ATTO647N dye features a distinct excitation/emission spectrum (λex: 645 nm, λem: 669 nm), placing it in the far-red range. Its exceptional photostability, minimal bleaching, and low background fluorescence make it ideal for super-resolution microscopy, including STED, PALM, and STORM imaging. Researchers widely favor ATTO647N for its robust signal and compatibility with demanding experimental conditions, making it a gold standard for single-molecule localization studies.
This antibody is preservative-free, ensuring compatibility with sensitive live-cell imaging and other advanced applications. Its high fluorescence quantum yield and minimal non-specific binding support precise target detection, even in complex biological environments. With its proven reliability and performance, ATTO647N remains a trusted choice for critical fluorescence assays.
Specification
Immunofluorescence: 1:500–1:1500, Degree of Labeling (DOL): 2-9, Unconjugated dye ≤5% of total fluorescence.
Optical Properties
λex: 645 nm, λem: 669 nm
Properties
Form
Lyophilized
Nominal concentration
2 mg/ml (after reconstitution with buffer)
The antibody is shipped in unit sizes of 1.0 mg as a lyophilized powder, shipped at room temperature. To reconstitute the antibody before use, a glycerol buffer is included for convenience. This allows to re-freeze the antibody after use at -20°C, to keep the quality and/or to prepare aliquots, which can be stored at -20.
Content
1.0 mg Goat Anti-Guinea Pig IgG (H+L) ATTO647N
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 effectively removed all goat serum proteins, including immunoglobulins not specifically binding to guinea pig IgG. After conjugation to the dye, the antibody was further purified by gel filtration, resulting in a highly pure and specific antibody.
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.
