Cat. #: 2109-1MG
Applications
Ideal for multiplexing approaches and live cell techniques, containing no preservatives for compatibility with sensitive applications.
Description
| Product name | Goat Anti-Mouse IgG (H+L) ATTO490LS | GXM ATTO490LS |
| Target species | Mouse |
| Description |
ATTO-labeled secondary antibodies represent a new generation of fluorescent reagents, defined by their exceptional fluorescence intensity and outstanding photostability. Goat Anti-Rabbit 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 exhibits a distinct excitation/emission spectrum (λex: 496 nm, λem: 6661 nm), providing outstanding compatibility with fluorescence microscopy and flow cytometry platforms. Its strong fluorescence signal, low background, and enhanced photostability support robust and reproducible data collection in complex biological samples. This antibody is preservative-free, making it compatible with a broad range of applications, including live-cell imaging and other sensitive techniques. Its minimal non-specific binding and strong fluorescence properties ensure high performance under challenging experimental conditions. |
| Specification | Immunofluorescence: 1:500–1:1500, Degree of Labeling (DOL): 2-9, Unconjugated dye ≤5% of total fluorescence. |
| Optical Properties | λex: 496 nm, λem: 661 nm |
Properties
| Form | Lyophilized |
| Nominal concentration | 2 mg/ml (after reconstitution) 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°C. |
| Content | 1.0 mg Goat Anti-Mouse 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 mouse IgG. Following conjugation to ATTO490LS 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.
