Immunoassay Optimization Buffers

CANDOR Immunoassay Optimization Buffers and Diluents are designed to reduce assay interference and improve the reliability, sensitivity, and reproducibility of immunoassays.

LowCross-Buffer®, our premium optimizer, acts as both an assay diluent and optimizer by minimizing nonspecific binding, cross-reactivities and matrix effects in immunoassays while preserving high-affinity antibody-antigen interactions. For more challenging interference, LowCross-Buffer® STRONG provides stronger suppression of unwanted low- and medium-affinity interactions.

Assay Defender®, provides additional protection against HAMA, human anti-animal antibodies, rheumatoid factors, and other high-affinity antibody interference that can contribute to false-positive or false-negative results. This is a great choice for auto-immune research.

Other popular buffers include Coating Buffer for adsorptive immobilization in ELISA, the dilution buffer Sample Buffer for less demanding applications, and Washing Buffer for removing interfering unbound and excessive components. 

CANDOR optimization buffers support ELISA, lateral flow assays, Western blotting, IHC, protein arrays, multiplex assays, Immuno-PCR, and other immunoassay applications.

With our range of optimizing buffers, you can find the perfect solution for your application.
