46 Multiplex Tyrosine Capture ELISA Assay

Receptor tyrosine kinases (RTKs) play important roles in converting signals from extracellular to intracellular.  Tyrosine autophosphorylation generates recruitment sites for downstream signalling proteins containing Src homology-2 (SH2). Binding of different SH2 domain-containing signalling proteins represents the activation of different signalling pathways. The SH2 domain-based RTK profiling kit from Signosis is an ELISA-like assay, allowing the simultaneous measurement of 46 SH2 domain bindings using either cell lysate or peptides.  This allows the activation of signalling pathways to be assessed through quantitative examination of SH2 domain binding. 


  1. Multiplex - A single assay measures the interaction of RTK with 46 SH2 domains.
  2. Quantitative - The difference between individual proteins in the interaction of the SH2 domains can be quantitatively compared. 
  3. Simple - The assay is performed using the same procedure as an ELISA.

  1. Hi! This is a good read. You have such an interesting and informative page. I will be looking forward to visit your page again and for your other posts as well. Thank you for sharing your thoughts about multiplex assay in your area. I am glad to stop by your site and know more about multiplex assay. Keep it up!
    Multiplex PCR for applications requiring the amplification or sequencing of DNA or RNA.
    More recently new technologies have been introduced that allow the testing of multiple biomarkers in a single assay. Doing this with immunoassays is difficult and the level of cross-talk between individual assays within the multiplex are difficult to measure and often lead to significant variation in results between labs and over time.
