Description
| Product name | Goat Anti-Human IgG ATTO647N | GXHu ATTO647N |
| Target species | Human |
| 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-Human IgG ATTO647N 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. ATTO647N exhibits a distinct excitation/emission spectrum (644/669 nm), making it a highly preferred fluorophore for advanced fluorescence applications in the far-red spectrum. Its outstanding photostability and exceptionally high fluorescence quantum yield allow for prolonged imaging sessions with minimal photobleaching, a crucial feature in techniques such as super-resolution microscopy (STED, PALM, STORM) and live-cell imaging. ATTO647N is particularly favored due to its low background autofluorescence, which ensures high signal-to-noise ratios even in complex biological samples. Additionally, its optimal compatibility with commonly used red lasers (e.g., 633 nm or 647 nm excitation sources) and minimal spectral overlap make it ideal for multiplexing alongside other fluorophores. These attributes have established ATTO647N as a gold standard in applications demanding precise and reliable detection, such as fluorescence lifetime imaging microscopy (FLIM), Förster resonance energy transfer (FRET), and flow cytometry. 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. |
| Specification | Immunofluorescence: 1:500–1:1500, Degree of Labeling (DOL): 2-9, Unconjugated dye ≤5% of total fluorescence. |

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 Goat Anti-Human IgG ATTO647N 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 human 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 purest reagents in Milli-Q™ water, as described in our publications.
