Cat. #: 3501-1MG
Applications
Suitable as a secondary antibody for immunofluorescence microscopy, flow cytometry, western blotting, and ELISA, depending on assay optimization and detection system.
Description
| Product name | Sheep Anti-Mouse IgG ATTO390 (H+L) - SXM ATTO390 |
| Target species | Mouse |
| 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. Sheep Anti-Mouse IgG ATTO390 (H+L) is 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: 476 nm), providing excellent compatibility with UV-excitable systems and minimizing spectral overlap in multiplex imaging setups. Its strong fluorescence signal and low autofluorescence background support detection of low-abundance targets and 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 support accurate target detection, while the robust fluorescence properties allow consistent results in advanced techniques such as super-resolution microscopy, flow cytometry, and fluorescence resonance energy transfer (FRET) assays. |
| Specification | Immunofluorescence: 1:500–1:1500, Degree of Labeling (DOL): 2-9, Unconjugated dye ≤5% of total fluorescence. |
| Optical Properties | λex: 390 nm, λem: 476 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°C. |
| Content | 1.0 mg Sheep Anti-Mouse IgG ATTO390 (H+L) 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 sheep serum proteins, including immunoglobulins not specifically binding to mouse 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. |
Buffers and antibodies from Hypermol® are made of the ultrapure reagents in Milli-Q™ water, as described in our publications.
