Description
| Product name | Goat Anti-Rat IgG ATTO390 (H+L) | GXRt ATTO390 |
| Target species | Rat |
| Description |
ATTO-labeled secondary antibodies represent a new generation of fluorescent reagents, characterized by their exceptional fluorescence intensity, superior photostability, and consistent performance across various applications. Goat Anti-Rat IgG ATTO390 (H+L) is specifically optimized for high-resolution microscopy, offering remarkable photostability and a high fluorescence quantum yield. These properties enable prolonged imaging sessions with minimal photobleaching, ensuring sharp and reliable signals. ATTO390 exhibits a distinct excitation/emission spectrum (λex: 390 nm, λem: 479 nm) with a long Stokes shift, providing excellent compatibility with UV-excitable systems and minimizing spectral overlap in multiplex imaging setups. Its strong fluorescence signal and low autofluorescence background make it highly effective in detecting low-abundance targets and achieving precise spatial resolution, even in dense or complex biological samples. This antibody is preservative-free, making it suitable for live-cell imaging and other sensitive applications requiring minimal interference. Its low non-specific binding and high affinity ensure accurate target detection, while its robust fluorescence properties allow consistent results in advanced techniques such as super-resolution microscopy, flow cytometry, and fluorescence resonance energy transfer (FRET) assays. |
