Labeling Kit

The essence of biochemical conjugation labeling lies in utilizing the specific affinity between biomolecules along with chemical conjugation reactions to covalently or non-covalently combine effector molecules with recognition capabilities with labels possessing detection, modification, and regulatory functions. Antibodies, functional proteins, peptides, nucleic acids, and small bioactive molecules serve as core effector carriers, playing a crucial role in target recognition and specific binding; various fluorescent agents, enzymes, and biofunctional modification materials serve as labels, responsible for signal output, performance optimization, and functional enhancement.

In life science research, antibody labeling is a very common and important technique. By conjugating antibodies with fluorescent dyes, enzymes, luminescent groups, or other functional molecules, antibodies can be endowed with new detection capabilities, making them widely used in experiments such as immunofluorescence (IF), flow cytometry (FCM), immunohistochemistry (IHC), Western blot, ELISA, and protein localization analysis.

In the world of biomedical research, clinical diagnostics, and drug development, antibodies are the "exclusive detectors" that precisely identify specific antigens. However, antibodies themselves cannot be directly captured by the naked eye or instruments. To make their recognition process "visualizable, quantifiable, and traceable," antibodies must be bound with special "signal tags" — this is the core principle of antibody labeling technology.

Currently, phycobiliproteins have become irreplaceable fluorescent labeling systems in flow cytometry, multiplex immunofluorescence, immunohistochemistry, and immunoassay platforms, with phycoerythrin (PE) and allophycocyanin (APC) being the most widely used.

Fluorescent labeling technology is one of the most important visualization tools in modern life science research. From intracellular protein localization and gene expression monitoring to immune cell typing, multi-parameter flow analysis, and spatial biology research, fluorescent signals are almost ubiquitous throughout the life science experimental workflow.
