Current mainstream immunodiagnostic methods include chemiluminescence immunoassay, latex immunoturbidimetry, and immunochromatography. We can provide a diverse range of key raw materials, such as magnetic microspheres, latex microspheres, and time-resolved microspheres, capable of meeting application needs.

1. Chemiluminescence Immunoassay

Self-developed Anti-CA153-093 mAb (Cat. No.: BP0011) was conjugated toCarboxyl-Activated MagPoly Beads (Cat. No.: MP1201) using a two-step method. Key performance evaluations, including reaction kinetics, precision, and clinical correlation, were conducted in an acridinium ester direct chemiluminescence system (Instrument: Yingkai 12910).

2. Latex Immunoturbidimetry

Various antibodies were modified onto different latex microsphere products (developed independently by BioG) via activation, conjugation, and blocking steps. Reactivity was assessed on a fully automated biochemical analyzer (Instrument: Hitachi 7180).

3. Immunochromatographic Assay

Depending on your application direction and specific needs, carriers such as colloidal gold, time-resolved microspheres, or fluorescent microspheres can be selected for protein/antibody conjugation and modification to qualitatively or semi-quantitatively evaluate raw material performance.
