Anti-Rabbit IgG-ATTO 488 antibody produced in goat

Goat anti-Rabbit IgG-ATTO 488 is a fluorescently labeled secondary antibody designed for immunofluorescence workflows where rabbit primary antibodies are used. The ATTO 488 fluorophore provides green fluorescence for visualizing antigen localization in fixed samples, and the goat IgG format supports robust binding to rabbit IgG targets. This reagent is commonly employed in microscopy and fluorescence-based assays to generate bright, spatially resolved signal from antibody-based recognition.

1. Immunofluorescence Microscopy

Goat anti-Rabbit IgG-ATTO 488 is frequently used as a secondary antibody in fluorescence microscopy to visualize rabbit IgG-bound antigens in fixed cells, tissues, and immunostained samples. Researchers in cell biology, biomaterials research, and microscopy core facilities use this conjugate to build multicolor staining panels by pairing the ATTO 488 emission with other fluorophores while keeping the rabbit primary antibody as the specificity anchor. The antibody format supports consistent labeling over standard immunostaining workflows, enabling clear imaging of target distribution across cellular compartments or extracellular matrices.

2. Flow Cytometry Antibody Staining

Goat anti-Rabbit IgG-ATTO 488 is used in flow cytometry workflows for fluorescence readout of rabbit primary antibody binding on cells or beads. In assay development and analytical immunophenotyping, laboratories employ this secondary conjugate to amplify fluorescence signal from rabbit-targeted primary antibodies, facilitating quantification of staining intensity and gating-based analysis. The dye conjugation enables integration into standard fluorescence channels for green detection, supporting routine comparative studies across experimental conditions.

3. Western Blot Fluorescent Detection

Goat anti-Rabbit IgG-ATTO 488 supports fluorescence-based immunodetection in protein analysis workflows, including fluorescent Western blot imaging where rabbit primary antibodies are followed by a labeled secondary. In protein biochemistry and chemical biology laboratories, this conjugate is used to visualize bands corresponding to target proteins with antibody-based specificity, using ATTO 488 fluorescence for instrument readout. The secondary antibody format helps standardize detection across different rabbit primary antibodies while maintaining consistent fluorescent labeling chemistry.

4. Immunoassay Signal Generation

Goat anti-Rabbit IgG-ATTO 488 is applied in fluorescence immunoassays where rabbit primary antibodies are used to capture or recognize analytes, and a fluorescent secondary antibody provides the measurable signal. Researchers developing research-grade biosensing platforms, binding assays, and antibody-based detection reagents use this conjugate to generate a robust fluorescent readout compatible with plate-based fluorescence instrumentation. The goat IgG secondary design supports streamlined assay construction by separating target recognition (rabbit primary) from signal generation (ATTO 488-labeled secondary).
