Used in research and diagnostic applications to detect polycaprolactone-based materials, particularly in biomedical engineering and drug delivery systems. Helps in evaluating the degradation and biocompatibility of PCLA-based polymers in vivo. Employed in immunoassays to monitor antibody responses against PCLA in preclinical studies. Supports development of biomaterials by providing a specific immunological tool for tracking PCLA distribution and immune interactions.
