Affinity purified for best signal to noise ratios and highest sensitivity
Most of the secondary antibodies offered by BioCat are affinity purified to provide the best signal to noise and detection sensitivity. Affinity purification not only selects for the most specific binding antibodies, but it also removes unwanted pre-immune immunoglobins and serum proteins that tend to result in high background noise or non-specific assay results.
A series of different labels are offered for each antibody type so that primary antibodies can be detected in wide variety of assays.
Whether you simply need a clean peroxidase-labeled antibody for western blotting or you need a fluorescent marker such as FITC or TRITC, the right antibody is available.
