The AlphaLISA® biotin-free immunoassay kit for chloramphenicol enables the quantitative determination of chloramphenicol in buffered solution, milk and cell culture supernatants using a homogeneous AlphaLISA assay (no wash steps). The kit utilizes a Digoxigenin (DIG) / Anti-DIG interaction as opposed to the traditional Streptavidin/Biotin interaction. This enables optimal performance when working with biotin-rich media (e.g. RPMI) or samples containing endogenous biotin.

Chloramphenicol is a broad spectrum antibiotic derived from the bacterium, Streptomyces venezuelae, that can be used to treat infections such as meningitis, plague, cholera, and typhoid fever. Due to its severe side effects, blood levels during treatment are monitored closely. The use of chloramphenicol to treat food-producing animals is banned in the United States, Canada, EU, and Australia due to the high potential risk of severe side effects. Food and water sources are strictly monitored for residues as any supply that is contaminated with chloramphenicol producing bacteria can result in exposure to humans.
AlphaLISA technology allows the detection of molecules of interest in a no-wash, highly sensitive, quantitative assay. In an AlphaLISA biotin-free assay, a DIG-labeled anti-analyte antibody binds to the anti-DIG-coated Donor beads while another anti-analyte antibody is conjugated to AlphaLISA Acceptor beads. In the presence of the analyte, the beads come into close proximity. The excitation of the Donor beads causes the release of singlet oxygen molecules that triggers a cascade of energy transfer in the Acceptor beads, resulting in a sharp peak of light emission at 615 nm.
