Optimized for fluorescence microscopy, flow cytometry, and other fluorescence-based applications, containing no preservatives for compatibility with sensitive assays.
ATTO-labeled secondary antibodies represent a new standard in fluorescence labeling, combining exceptional brightness, superior photostability, and reliable performance. Goat Anti-Guinea Pig IgG ATTO565 is specifically engineered for applications demanding high sensitivity and resolution.
The ATTO565 dye features an excitation/emission spectrum (λex: 564 nm, λem: 590 nm) that ensures optimal compatibility with red fluorescence channels and reduces spectral overlap. Its bright fluorescence signal and low background autofluorescence make it highly effective for detecting low-abundance targets, even in complex samples.
This antibody is preservative-free, making it suitable for sensitive applications such as live-cell imaging, fluorescence resonance energy transfer (FRET), and advanced microscopy. Its high fluorescence quantum yield and minimal non-specific binding provide consistent results across a wide range of experimental conditions.
Specification
Immunofluorescence: 1:500–1:1500, Degree of Labeling (DOL): 2-9, Unconjugated dye ≤5% of total fluorescence.
Optical Properties
λex: 564 nm, λem: 590 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) ATTO565
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.
