The AlphaPlex™ 545 (Terbium) Human TNFα Detection Kit is designed for the quantitative determination of human TNFα together with another analyte (AlphaLISA) in serum, buffered solution or cell culture medium using a homogeneous (no wash steps, no separation steps) assay.
AlphaPlex technology allows the detection of molecules of interest in a no-wash, highly sensitive, quantitative assay. In an AlphaPlex assay, a biotinylated anti-analyte antibody binds to the Streptavidin-coated Donor beads while another anti-analyte antibody is conjugated to AlphaPlex 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 545 nm.
AlphaPlex reagents are intended for use in conjunction with AlphaLISA reagents in multiplexing assays.

The introduction of enzyme-linked immunosorbent assays (ELISAs) in the early 1970’s offered researchers a non-radiometric immunoassay platform without compromising sensitivity. Over the last 50 years scientists have made huge strides in disease research and drug discovery and a demand for greater ...
This application note describes how AlphaPlex reagents from PerkinElmer can be used to simultaneously detect IL-6 and IL-8 secretion by cell lines.
The balance of glucagon and insulin levels within the body is an important indicator of the function of metabolism. Healthy metabolic function is characterized by elevated levels of one of these hormones and lowered levels of the other. Simultaneous high levels generally indicate hyperglycemia or ...
