SEROMAX is a sample collection kit which only requires a pin-prick amount of blood for quantifying antibodies or autoantibodies. Conventional antibody sample collection methods require patients to visit a clinical site where a physician would commonly need to draw a minimum of 0.5 ml of blood. This is followed by costly cold chain processes before the sample reaches a test laboratory for assay and analysis. By using a proprietary matrix to stabilise antibodies, the SEROMAX kit simplifies this process, enabling shipping at room temperature. This is then combined with the ultra-high sensitivity of KREX protein arrays to produce results that are identical to conventionally collected samples.

Correlation between all proteins in peripheral blood and SEROMAX

Figure shows correlation plot matrix between peripheral blood, SEROMAX Day 5 and SEROMAX Day 10:

  • Peripheral blood and SEROMAX Day 5, R=0.92
  • Peripheral blood and SEROMAX Day 10, R=0.91
  • SEROMAX Day 5 and SEROMAX Day 10, R=0.98

Sengenics - Functional Proteomics | Krex Technology | Protein Array Supplier

Sengenics is a Functional Proteomics company that leverages its patented KREX technology to discover autoantibody biomarker signatures for prediction of drug response and severe immune-related adverse events (irAEs). KREX can also be used to identify autoantibody biomarkers to diagnose cancer, autoimmune, neurodegenerative or infectious diseases with higher sensitivity and specificity than conventional diagnostic tests. Some autoantibodies that are identified as diagnostic biomarkers may be protective and have potential in themselves as therapeutic biomolecules.
