• Optimizers for immunoassays enable better reliability and reproducibility by reducing coefficients of variations and by avoiding interference effects like HAMAs and cross-reactivities. 
  • Blockers enable saturation of free binding capacities on protein binding surfaces for reliable assays. Check out BIOAXXESS' Selection Guide for CANDOR's Blocker product range (with new PlateBlock).
  • Stabilizers Stabilizers for immunoassays allow long-term storage of antibodies, conjugates (like HRP-labeled) and antigens in solutions as well as coated onto surfaces like ELISA plates or others. During storage the good quality of the assay components can be conserved.
  • Buffer Solutions enable easy and fast working with immunoassays. All of these ready-to-use or 10x solutions are manufactured in our own facility according to DIN EN ISO 9001:2008. Therefore all products can be used directly in regulated areas like GLP laboratories (good laboratory practice) or for diagnostics kit production.
  • Buffers for ELISA, EIA, RIA, protein arrays, Western blotting and immuno-PCR (or immuno-histochemistry). CANDOR's state-of-the-art assay buffer and surface blocker minimize high background, assay-interferences and cross-reactivities are available in packages.
  • The Professional Developer Packages are suitable for all your ELISA buffer requirements, including the state-of-the-art assay buffers, surface blockers, standard and antibody-conjugate stabilizers in solution or when coated to a surface.
  • ReadyTector® is the All-in-One Solution for Western blotting. All-in-One means the entire process takes place in a single work step in a single solution.
  • These special offers apply to products with short shelf-lives and are valid as long as stocks last.
