Antibody produced in goat, affinity purified
Cat. #: 2704-1MG
Applications
Optimized for advanced fluorescence imaging, live-cell microscopy, and multiplex assays, containing no preservatives for compatibility with sensitive applications.
Description
| Product name | Goat Anti-Guinea Pig IgG (H+L) ATTO490LS | GXGP ATTO490 |
| Target species | Guinea Pig |
| Description |
ATTO-labeled secondary antibodies are highly advanced fluorescent tools, known for their superior photostability, high quantum yield, and exceptional performance in various fluorescence-based applications. Goat Anti-Guinea Pig IgG ATTO490LS is distinguished by its exceptionally large Stokes shift of 165 nm, enabling excellent separation between excitation and emission wavelengths, making it particularly suitable for multiplexing applications. The ATTO490LS dye features a large Stokes shift and an excitation/emission spectrum (λex: 490 nm, λem: 515 nm), offering excellent spectral separation, minimizing spectral overlap and autofluorescence for clearer signal detection in multiplexing applications. This antibody is preservative-free, enabling compatibility with sensitive applications such as live-cell imaging, super-resolution microscopy, and flow cytometry. Its low non-specific binding and robust fluorescence signal ensure reliable target detection in complex biological samples. |
| Specification | Immunofluorescence: 1:500–1:1500, Degree of Labeling (DOL): 2-9, Unconjugated dye ≤5% of total fluorescence. |
| Optical Properties | λex: 490 nm, λem: 515 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) ATTO490LS 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. |
| Remarks | For Use in Research only. Not for Use in Human or Veterinary Diagnostical or Therapeutical Applications. |
| CAS no. |
Buffers and antibodies from Hypermol® are made of the purest reagents in Milli-Q™ water, as described in our publications.
