80 nm spherical gold nanoparticles for covalent conjugation. The carboxyl surface can be conjugated to free amines in antibodies and proteins, allowing for greater stability, sensitivity, and control over particle-antibody loading. BioReady materials are engineered for reliable conjugation to antibodies, proteins, peptides, and other biomolecules. Ideal for lateral flow assays and other diagnostics. Each batch is extensively characterized to meet highest quality standards, ensuring reliable & reproducible results. All products supplied with batch-specific COA's with TEM, DLS, Zeta, & UV-Vis.
