Target proteins

Our scioDiscover and scioPhospho services are based on complex Antibody Microarrays, also called analytical Protein Arrays or Protein Capture Arrays. Within a single experiment 1030 proteins can be profiled in parallel requiring only minimal amounts of sample. The targets proteins were carefully selected over a period of more than 15 years to cover a broad set of different protein classes as well as pathways important in biomedical studies.

Thereby, the protein profiling covers key pathways in various diseases such as cancer, neurological disorders as well as organ failure. Given the wide spectrum of applications and indications the service is ideal for high-content protein expression level analysis from various biological samples. The broad coverage of many important pathways, extracellular and membrane proteins as well as transcription factors, renders scioDiscover a versatile and efficient tool for discovery projects.

Please find below the distribution of the proteins targeted by scioDiscover according their biological processes (Fig.1), their protein classes (Fig.2), their molecular function (Fig.3) as well as their cellular compartment (Fig.4). In addition, pathways covered by scioDiscover are listed in Table 1.

For the pathways TNF signaling, Cell cycle regulation and pathways important in Cancer, Tuberculosis and Huntington's Disease covered targets are depicted in green.

Please contact us for more information regarding targets and pathways covered or to discuss how we can support your study with a highly-parallel protein analysis.
