  • Because of the complexity and long time commitments involved in the development of such assays, particularly highly specific or efficient assays and immunoassays, many pharmaceutical companies, biotechs, and academic institutions have found that it becomes a bottleneck, holding up valuable research. (genscript.com)
  • GenScript's efficient and reliable antibody production and immunoassay development services provide a solution to this problem, delivering top-quality assays and freeing up necessary staff and facilities. (genscript.com)
  • Multi-step assays are often called separation immunoassays or heterogeneous immunoassays. (wikipedia.org)
  • Such assays are called homogenous immunoassays or less frequently non-separation immunoassays. (wikipedia.org)
  • Immunoassays which employ enzymes are referred to as enzyme-linked immunosorbent assays (ELISAs), or sometimes enzyme immunoassays (EIAs). (wikipedia.org)
  • CD/DVD based assays could potentially be used for any immunoassay already in use and many assays used in analytical chemistry, as long as analytes have a corresponding probe, are soluble, and are large enough to alter the angle of incident. (wikipedia.org)
  • The hook effect or the prozone effect is a type of interference which plagues certain immunoassays and nephelometric assays, resulting in false negatives or inaccurately low results. (wikipedia.org)
  • Magnetic
  • Magnetic immunoassay (MIA) is a novel type of diagnostic immunoassay using magnetic beads as labels in lieu of conventional enzymes (ELISA), radioisotopes (RIA) or fluorescent moieties (fluorescent immunoassays). (wikipedia.org)
  • Beyond this requirement, MIA that exploits the non-linear magnetic properties of magnetic labels can effectively use the intrinsic ability of a magnetic field to pass through plastic, water, nitrocellulose, and other materials, thus allowing for true volumetric measurements in various immunoassay formats. (wikipedia.org)
  • This technology,makes magnetic immunoassay possible in a variety of formats such as: conventional lateral flow test by replacing gold labels with magnetic labels, vertical flow tests allowing for the interrogation of rare analytes (such as bacteria) in large-volume samples microfluidic applications and biochip It was also described for in vivo applications and for multiparametric testing.
