DigiWest® Protein Profiling Services

  • DigiWest® immuno-assays enable comprehensive analyses of up to 800 total & phospho proteins using just ~20-60 µg of total protein, from 2D/3D cells, xenografts, tissues or even sections (e.g. LCM)

  • DigiWest® studies are fully customizable, based on a list of currently 1,215 antibodies, including 321 antibodies against phospho-epitopes and other post-translational modifications (PTMs), with 50+ pre-defined pathway panels for human, mouse, rat, dog, cyno & minipig samples

  • DigiWest® represents a versatile platform for pathway profiling, drug MoA studies, compound characterization (small molecules, PROTACs, antibodies, etc.), biomarker discovery, and safety/tox

  • DigiWest® combines the robustness of Western blotting with the power of Luminex® bead-based multiplexing, and has been invented, developed and validated by Dr. Markus Templin's group at NMI

  • DigiWest® is being offered on a fee-for-service basis

  • New! Our new "Pathway Activity Panels" are designed to profile activation/ phosphorylation of key cell signaling pathways (RTK/RAS/RAF/ERK, PI3K/AKT, mTOR). As these pathways are frequently targeted by anti-cancer drugs, our Pathway Activity Panels are valuable for both clinical and pre-clinical samples. Contact us to get the list! And we have also just established DigiWest® for FFPE (formalin-fixed paraffin-embedded) samples ...

Imagine to get data on 80, 300, or even 800 total & phospho proteins from just 10-60 micrograms of protein sample. With DigiWest® you can!

Case study 1: DigiWest® for biomarker discovery

Analysis of mechanisms and biomarkers of platinum resistance

  • A set of 24 fresh frozen tumor specimens from relapsed vs cured platinum-treated ovarian cancer patients was analysed by DigiWest®, using 466 antibodies (total and phospho proteins) covering various cell signalling pathways.

  • DigiWest® protein signatures distinguished platinum resistant vs sensitive patients, and revealed 8 promising biomarker candidates.

Case study 2: DigiWest® for lead characterization

Mode-of-action study of compounds in comparison to reference drugs

  • Calu1 cells were treated with 1 MEK inhibitor vs 1 PI3K inhibitor vs 2 experimental lead compounds (data not shown) vs DMSO. Cell samples were analysed by DigiWest®, using 156 selected antibodies (total and phospho proteins) covering different signal transduction pathways.

  • DigiWest® yielded distinct signatures for each compound, and allowed in-depth characterization of lead compounds as compared to reference drugs.

Case study 3: DigiWest® in PD3D® tumor models

Protein profiling for characterization of primary tumor samples

  • In collaboration with cpo Cellular Phenomics & Oncology GmbH, primary patient-derived 3D tumor cell cultures (PD3D®) were profiled by DigiWest®, focusing on 122 antibodies for total and phospho proteins involved in a range of signaling pathways.

  • DigiWest® revealed pathway activation patterns that explained phenotypic differences in PD3D® drug responses as measured by cpo.

Case study 4: DigiWest® in multiple species

Multiplex protein profiling for safety/toxicology and in vivo pharmacology

  • A DigiWest® panel of >700 antibodies previously validated in human and mouse materials was tested in protein lysates from liver and kidney samples of rat, dog, minipig and cynomolgus origin.

  • This comprehensive validation project has yielded hundreds of antibodies for DigiWest® and Western blot studies, thus enabling protein profiling in safety/toxicology and in vivo pharmacology.
