Rabbit Anti-Guinea Pig IgG ATTO550 (H+L)
Antibody produced in Rabbit, affinity purified
Cat. #: 3707-1MG
Applications
Optimized for fluorescence microscopy, flow cytometry, and other fluorescence-based applications, containing no preservatives for compatibility with sensitive assays.
Description
| Product name | Rabbit Anti-Guinea Pig IgG (H+L) ATTO550 | RXGP ATTO550 |
| Target species | Guinea Pig |
| Description |
ATTO-labeled secondary antibodies represent a new standard in fluorescence labeling, combining exceptional brightness, superior photostability, and reliable performance. Rabbit Anti-Guinea Pig IgG ATTO550 is specifically engineered for applications demanding high sensitivity and resolution. The ATTO550 dye features an excitation/emission spectrum (λex: 554 nm, λem: 576 nm) that ensures optimal compatibility with red fluorescence channels and reduces spectral overlap. Its bright fluorescence signal and low background autofluorescence make it highly effective for detecting low-abundance targets, even in complex samples. This antibody is preservative-free, making it suitable for sensitive applications such as live-cell imaging, fluorescence resonance energy transfer (FRET), and advanced microscopy. Its high fluorescence quantum yield and minimal non-specific binding provide consistent results across a wide range of experimental conditions. |
| Specification | Immunofluorescence: 1:500–1:1500, Degree of Labeling (DOL): 2-9, Unconjugated dye ≤5% of total fluorescence. |
| Optical Properties | λex: 554 nm, λem: 576 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 Rabbit Anti-Guinea Pig IgG (H+L) ATTO550 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 rabbit 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. |
| 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 ultrapure reagents in Milli-Q™ water, as described in our publications.
