Which sample types can be analysed ?

With the scioDiscover service a variety of samples can be analysed:

  • plasma / serum
  • fresh frozen tissue samples
  • cellular content
  • cell culture supernatant
  • cerebrospinal fluid
  • additional sample types on request
  • studies possible in samples from human, mouse or rat*

* Antibody array is designed to target human proteins. Due to a high sequence homology of vast majority of proteins it was often successfully applied to study murine, rat and ovine models as well  [Thorenz A. et al. (2018), Peiro J. et al. (2018), Reichman H. et al. (2019), Raquel F. et al. (2020)].

Sample-to-result serviceAntibody microarray workflow

Within our analysis service, we will not only carry out the microarray experiments but also support you with a suggestion for an appropriate microarray study design as well as with the sample selection process in order to address your scientific question in the optimal way. Within 3-4 weeks after receipt of your samples you will receive a customised study report including a statistical analysis.

Our analysis service includes:

  • definition of an appropriate study design

New article | Biomarker identification and verification in endometriosis

| 22th Oct 2021 | Scientists at University Medical Centre Ljubljana used our scioDiscover platform for a biomarker identification in endometriosis:

"Discovery proteomics using antibody microarrays that covered 1360 proteins identified 16 proteins with different levels in cases versus the control patients. The validation using an ELISA approach confirmed significant differences in the levels of cartilage oligomeric matrix protein (COMP) and transforming growth factor-β-induced protein ig-h3 (TGFBI) and nonsignificant differences in angiotensinogen (AGT). "

New article | Selective elimination of immunosuppressive T cells in patients with multiple myeloma

| Feb 2021 | Scientists at Heidelberg University Hospital used our scioCD  platform to profile CD8+SLAMF7+ cell cultures:

"High throughput screening of 351 different cytokines and immune proteins in the supernatants of the T cells cultures revealed strong upregulation of IL-6, IL-8, both vital survival factors for myeloma cells, and CXCL5, a chemokine that could enhance the frequency of CD4 Treg, in the cultures containing CD8+SLAMF7+ cells. IL-2 and IL-5 were upregulated in the control cultures without CD8+SLAMF7+ T cells, highlighting a more activated state in the control group and suggestion IL-6 and IL-8 as potential effector cytokines for the suppressive CD8+SLAMF7+ T cells."

New article | Analysis of the Differential Gene and Protein Expression Profiles of Corneal Epithelial Cells Stimulated with Alternating Current Electric Fields

| Feb 2021 | Scientists at Rostock University Medical Center used our scioCD  platform to Corneal Epithelial Cells stimulated with Alternating Current Electric Fields:

"Analysis of the protein array data revealed that the treatment of cells with AC EFs altered the expression of various protein products ... revealed activation of various diverse cellular signaling pathways in which TNF, MAPK, IL17, and PI3K-Akt signaling pathways were significantly impacted ..."

New article | BET-Inhibitor I-BET762 and PARP-Inhibitor Talazoparib Synergy in Small Cell Lung Cancer Cells

| Dec 2020 | Scientists at University of Sassari used our scioPhospho  platform to to analyse the synergy of BET and PARP inhibition in Small Cell Lung Cancer Cells:

"Among the I-BET762-associated and combination-associated differentially expressed proteins, 150 were common to both treatment conditions. ... Ranking I-BET762-associated and combination-associated DEPs by their differential expression revealed CHEK2 and PTEN to be among the top-downregulated proteins, whose deficiencies have been associated with HR defects and increased PARPi sensitivity. "

Dr. Joachim Lupberger 

Institute for Viral and Liver Disease, Inserm U1110, University of Strasbourg, LabEx HepSYS, Strasbourg, France

"Our lab is focusing on the identification of minimal-invasive biomarkers for liver disease progression. A challenge of our humanized animal models for liver disease is the low volume of blood samples available, which did not pose any problem for the analysis. I was pleased by the prompt, friendly, and uncomplicated contact and was impressed by the results and the thorough report we received. The overall quality was excellent, which made us to continue using the service of Sciomics for follow-up projects analyzing patient material."

 Prof. Dr. Andreas Weigert 

Goethe-University Frankfurt, Faculty of Medicine, Institute of Biochemistry I, Frankfurt, Germany

"We were under considerable time pressure to gain comprehensive information about cytokine/chemokine levels in a mouse model of self-resolving inflammation. To add to our misery, we had only a small number of biological replicates to run the analyses. Thankfully, the team at Sciomics were able to come to our rescue by providing a very prompt analysis, without neglecting to properly communicate the procedure, potential caveats and other details. The whole process was a very satisfying experience, rather like working with committed colleagues than with a company, and we got great data out of the project. I do happily recommend working with Sciomics for targeted proteomics analyses."
