Latex Microspheres

The latex microspheres feature a polymer matrix with a controlled number of surface carboxyl groups, introduced through a proprietary surface modification process. These carboxyl groups enable stable covalent bonding with amino groups on biomolecules including antibodies, antigens, peptides, and
oligonucleotides, ensuring strong and reliable conjugation. With excellent particle uniformity, this microsphere platform is ideally suited for product development in advanced diagnostic applications such as particleenhanced immunoturbidimetry (PET), agglutination assays, and solid-phase immunoassays.
