Based on years of experience in the conjugation of particles and antibodies, Creative Biolabs is capable of providing high-quality, efficient and cost-saving particle conjugation services that are highly customizable for global customers. Our particle conjugation services include colloidal gold, colored or uncolored latex, fluorescent latex, nanoparticles, and magnetic particles. These services can be part of an antibody production project or as a stand-alone service.

What Is Particle Conjugation?

Conjugation of proteins or antibodies of interest with various molecular labels is very common in biological research. In particular, these conjugations have greatly facilitated the detection of labeled protein, its binding partners, or antigens, in the case of labeled antibodies. More recently, multifunctional particles, including colloidal gold, nanoparticles, and magnetic particles, have been developed for various biological applications, such as biomolecule separation, cellular and molecular detection, as well as drug delivery. What’s more, particles, in particular, nanoparticles, are extensively used in multiplexing biomolecule assays, which including but not limited to agglutination tests and assays, particle capture ELISA methods, polymerase chain reaction (PCR) tests, superparamagnetic-based assays, and as fluorescent labels or stains for detecting biological molecules.
