Immunoassay Kits
Immunoassay kits are a sensitive means of detecting and quantifying proteins, antibodies, or antigens with specificity. By offering optimized reagents, standards, and detection systems in ready-to-use form, they simplify experimental procedures and achieve reproducible, consistent results across diagnostics, biomarker investigation, and basic research applications.
