PE conjugated anti-cat primary antibodies are fluorescent antibodies designed to detect feline antigens directly in biological samples. They combine cat-specific antigen recognition with phycoerythrin, a bright fluorophore that is especially useful in flow cytometry and fluorescence-based assays. This direct labeling format simplifies experimental workflows by eliminating the need for a secondary antibody.
Phycoerythrin Fluorescence Properties
Phycoerythrin is one of the brightest commonly used fluorophores, with strong excitation and intense emission that make it highly effective for detecting low-abundance targets. It is especially useful in multicolor experiments where a strong signal is needed in a well-defined fluorescence channel. Because of its brightness, PE is often chosen when sensitivity is a priority.
Antibody Specificity and Labeling
These antibodies are produced to recognize cat-specific proteins, which may include immune cell markers, tissue antigens, or disease-related proteins. The phycoerythrin molecule is covalently linked to the antibody in a way that preserves antigen-binding activity as much as possible. Since the antibody is directly conjugated, it allows rapid and straightforward detection of feline targets.
Applications in Feline Research
PE conjugated anti-cat primary antibodies are commonly used in flow cytometry, immunophenotyping, and fluorescence microscopy. They are valuable in studies of feline immune responses, infectious disease, inflammation, and cellular biomarker expression. Their strong fluorescence makes them particularly useful for detecting markers that are present at low levels.
