Immunological Assays

Roche Raw Materials – Proven Diagnostics Quality

As a manufacturer of diagnostic kits, and the leading provider of raw materials for diagnostic immunoassays, we completely understand the needs of diagnostic companies. The depth of our portfolio allows you to work with a single strategic partner to bring your kit to market, without the complexity of managing multiple suppliers.


Heterogeneous and Homogeneous Immunoassays

Diagnostics manufacturers demand antibodies and antibody mixes of proven quality specifically produced for use in diagnostic kits. CustomBiotech offers a dedicated product line of high-quality antibodies and antigens for use in heterogeneous and homogeneous immunoassays.


Labeling & Detection

Most immunoassays today depend on the use of an analytical reagent that is associated with a detectable label. Complete the detection step of your immunoassay by applying our hapten and fluorescent labels, antibody conjugates, streptavidin/biotin, gold, and excellent marker enzymes (e.g., rec. alkaline phosphatase, HRP, and ß-Galactosidase).


Assay Interference

In diagnostic immunoassay development and kit manufacturing, consistent high performance and quality is key to market success and a manufacturer’s reputation.

Immunoassay interference poses a significant threat to assay quality, and its impact is far-reaching. False and unreliable assay outcomes due to interference can lead to misinterpretation of patient results and incorrect treatment. As a result, complaints lead to mistrust of all products within a brand, and trigger costly and time-consuming troubleshooting and assay rework. Optimal blocking technology can be the critical element that eliminates potential interferences and positions your product above the competition.

The Roche CustomBiotech Immunoassay Interference Blocker portfolio consists of a broad selection of powerful blockers designed to eliminate the most common types of immunoassay interference:  

  • antibody interferences (e.g. HAMA antibody interactions)
  • surface interferences
  • detection interferences.
