Applications for antibody microarrays

Antibody microarrays are a versatile tool.

Antibody microarrays are an efficient and cost-effective tool for the analysis of multiple proteins in parallel. Some advantages of an analysis based on antibody microarray are:

  • Lower antibody consumption as compared to standard assays such as ELISA
  • The highly parallel approach increases the probability to identify a protein biomarker candidate in a biomarker screening or verification study.
  • The parallel analysis of multiple target proteins facilitates a direct comparison of protein abundance in the very same experiment and set of samples.
  • Only minimal amount of sample such as 20 µL of plasma is needed to analyse hundreds of proteins. Therefore, multiplex analysis is feasible for low abundant samples.
  • A variety of sample types such as plasma, serum, tissue or samples from cell culture experiments can be analysed with the very same platform
  • A sample fractionation or a depletion of high abundant proteins such as albumin is not necessary. Thereby, the sample preparation is simplified and a potential bias can be prevented.
  • Where necessary, alternative immunological assays can be built comparably easy based on the very same antibodies.

Most of time antibody microarrays are used in biomedical studies. However, there are multiple other possibilities such as analysis and surveillance of food or the analysis of environmental samples.

New article | Anti-cancer activity and mechanism of action of metformin in endometrial cancer cells

| March 2021 | Scientists at Heidelberg University Hospital characterized the protein profile response of an endometrial cell line to Metformin treatment and hyperinsulinemia  with our scioDiscover platform:

"The presented data helps identify potential targets affected by metformin treatment in EC and allows for a better understanding of the mechanism of action of the biguanide drug’s anti-cancer activity.

With the presented data, we contribute to a better understanding of the anti-cancer activity of metformin as well as its underlying mechanism of action in EC cells."

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."

| 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.

Testimonials

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."
