Nano Flow’s Procalcitonin (PCT) gold conjugate is built on a highly specific monoclonal antibody targeting procalcitonin, a key biomarker for bacterial infection and sepsis. Validated as a detection antibody in lateral flow assays, this conjugate offers high sensitivity and reproducibility for rapid diagnostics. The corresponding capture antibody is also available, giving developers access to a complete antibody pair for assay development.
Procalcitonin (PCT) Gold Conjugate – 40 nm (Ref NF-PCT-AU)

Produced on Nano Flow’s highly spherical 40 nm gold nanoparticles (OD20), this conjugate ensures robust stability, batch-to-batch reproducibility, and strong visual signal intensity. It is suitable for both prototyping and large-scale manufacturing of rapid diagnostic assays.
Applications: Lateral flow assays (LF) and other immunoassay formats.
Certificate of Analysis: Supplied for each batch, including TEM, DLS, and UV-Vis characterization.
