FITC conjugated anti-cat primary antibodies are fluorescent antibodies designed to detect feline antigens directly in biological samples. They combine target specificity for cat proteins with the green fluorescence of fluorescein isothiocyanate, making them useful for microscopy, immunofluorescence, and flow cytometry. This direct labeling format simplifies workflows by removing the need for a secondary antibody.

FITC Fluorescence Properties

FITC is one of the most widely used fluorophores in immunology because it is easy to excite and detect on standard fluorescence instruments. It emits green light and is compatible with common filter sets, which makes it practical for routine laboratory use. However, its fluorescence can be sensitive to photobleaching, so protected handling and proper imaging conditions are important.

Antibody Specificity and Labeling

These antibodies are produced to recognize cat-specific antigens, which may include surface markers, structural proteins, or disease-related targets depending on the application. The FITC molecule is covalently linked to the antibody in a way that preserves antigen-binding activity as much as possible. Because the antibody is directly labeled, it provides a straightforward method for visualizing feline targets without a secondary detection step.

Applications in Feline Research

FITC conjugated anti-cat primary antibodies are commonly used in immunofluorescence, flow cytometry, and tissue staining studies. They are especially useful in investigating feline immune cells, inflammation, infection, and biomarker expression. In some experimental designs, they are also used to localize specific proteins in cells or tissue sections with moderate to strong fluorescence signal.
