Factor VIII (human) AlphaLISA Biotin-Free Detection Kit, 100 Assay Points

The AlphaLISA® Human BDNF Biotin-Free Detection Kit is designed for the quantitative detection of human Brain Derived Neurotrophic Factor (BDNF) in serum, cell culture medium, and other samples types using a homogeneous (no wash steps, no separation steps) assay. The biotin-free kit is compatible with high-biotin culture media and other sample types that contain high levels biotin.

The biotin-free kit uses anti-DIG (anti-Digoxin) Donor beads instead of streptavidin Donor beads, which makes the kit compatible with high-biotin culture media and other sample types that contain high levels biotin (including brain/liver tissue extracts, milk and eggs).


  • No-wash steps, no separation steps

  • Compatible with high biotin samples, including RPMI and high-biotin tissue extracts

  • ELISA alternative technology

  • Sensitive detection

  • Broad sample compatibility

  • Results in less than 3 hours


  • Our HV (100 assay point) kits allow you to run 100 wells in 96-well format, using a 100 µL reaction volume (10 µL of sample).
  • Our 500 assay point kit allows you to run 500 wells in 96-well or 384-well format, using a 50 µL reaction volume (5 µL of sample).
  • Our 5,000 assay point kit allows you to run 5,000 wells in 96-well or 384-well format, using a 50 µL reaction volume (5 µL of sample).

Brain Derived Neurotrophic Factor (BDNF) is a neurotrophin that acts within the central and peripheral nervous systems. BDNF is expressed in a pro-form as pro-BDNF then later cleaved by plasmin, furin, or pro-convertase enzymes to become the mature form of BDNF. Released BDNF has been observed to bind to both TrkB and LNGFR (p75) receptors. Acting on these receptors, BDNF helps to support the differentiation of new neurons and synapses, promote neuron growth, and generally promote the survival of existing neurons. BDNF has been observed to potentially play a role in several major diseases such as Alzheimer’s, Parkinson’s and Huntington’s disease. This kit has been designed for the detection and quantification of BDNF in serum, and cell culture supernatants.

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.
