PE/Atto 594 conjugated anti-cat primary antibodies are fluorescent immunoreagents designed to detect feline antigens with high sensitivity in fluorescence-based assays. They combine the specificity of an anti-cat primary antibody with a bright red-emitting fluorophore system, making them useful for imaging, flow cytometry, and multicolor analysis. This format is particularly valuable when strong signal intensity and good spectral separation are required.

Fluorescent Properties

PE and Atto 594 are both known for strong fluorescence output, which supports sensitive detection of low-abundance targets. Their emission in the red/orange-red range makes them useful in panels where green and far-red channels are already occupied. These properties help reduce overlap with commonly used dyes such as FITC and PE-Cy5-type conjugates.

Antibody Specificity and Labeling

The anti-cat primary antibody component is directed against feline-specific antigens, which may include cell surface markers, structural proteins, or disease-associated molecules. The fluorophore is covalently attached to the antibody to preserve antigen recognition while enabling direct visualization. Because the antibody is already labeled, no secondary antibody is required for detection.

Applications in Feline Research

These conjugated antibodies are commonly used in immunofluorescence, confocal microscopy, and flow cytometry. They are especially useful for studying feline immune cells, tissue localization of proteins, and biomarker expression in disease models. In multiplex experiments, they can support simultaneous detection of several targets with minimal assay complexity.
