GENEWIZ FAQ:
What proteomics services does GENEWIZ offer?
We offer high-throughput protein biomarker discovery using Olink®'s Proximity Extension Assay (PEA) technology. This includes pre-designed Reveal, Target, and Explore panels, as well as custom Focus and Flex panels to meet research or clinical needs.
What is PEA (Proximity Extension Assay) technology?
Olink®’s PEA technology uses paired antibodies linked to DNA oligonucleotides which generate a signal only when bound to their target protein, providing exceptional specificity with minimal sample input (as little as 1 µL).
Which Olink® panels are available through GENEWIZ?
As a Certified Service Provider, we support a wide variety of Olink® panels including:
- Explore HT: High-plex targeting >5,400 proteins
- Reveal: High-plex targeting >1,000 proteins
- Target 96: Mid-plex targeting 92 proteins
- Disease areas: cardiovascular disease II, cardiovascular disease III, oncology, oncology III, neurology, inflammation, immuno-oncology
- Biological processes: cardiometabolic, cell regulation, neuro-exploratory, immune response, development, metabolism, organ damage
- Target 48: Mid-plex targeting up to 45 proteins
- Cytokine, immune surveillance, mouse cytokine
- Custom Focus/Flex Panels: Flexible assay development combining 5-30 biomarkers in a single panel
A full list of biomarkers included in each panel is available on our Proteomics webpage.
What is the price for proteomics?
Please submit a quote request to receive accurate pricing information, as the cost depends on the details of the project.
You can also contact the GENEWIZ NGS team by submitting an inquiry.
What sample types can be used with Olink®?
Olink® panels are compatible with cell-free fluids. The most common are plasma and serum. We also accept other sample types such as cell and tissue lysates, CSF, saliva, urine, cell culture media, fine needle biopsies, exosomes, microdialysis fluid, bronchoalveolar lavage fluid, dried blood spots, synovial fluid, plaque extract and more.
For detailed sample submission requirements, please visit our Sample Submission Guidelines.
How much volume do I need to provide?
While the minimum input amount varies from 1-6 µL depending on the Olink® panel, we recommend submitting 40 µL per sample for best results. For cell and tissue lysates, 0.5–1.0 µg/µL protein concentration is ideal.
What if my samples contain viruses or infectious materials?
We can accept BSL1 and some BSL2 samples. Please indicate any viral or infectious materials present in the sample in the Special Comments section of your quote, and the NGS team will advise.
Are FFPE samples supported for Olink®?
Not currently; FFPE preservation degrades proteins and is not compatible with PEA technology.
How many samples are required?
To optimize throughput and cost:
- Explore HT: 86 samples
- Reveal: 86 samples
- Target 96: 88 samples
- Target 48: 40 samples
- Flex/Focus: 40 samples
Can I create a custom panel with GENEWIZ?
Yes, we support custom Focus and Flex panel development, which allows you to choose from validated or novel proteins.
Is it possible to incorporate proteins that are not part of Olink® panels?
Yes, please submit an inquiry to discuss adding custom or novel targets using available technologies.
Why is randomization important?
Randomizing your samples minimizes bias and ensures technical variation does not confound biological results. Refer to GENEWIZ's Plate Randomization Guidelines to effectively randomize your samples for optimal results.
GENEWIZ offers sample transfer and randomization (additional costs incurred). Please submit an inquiry to discuss your project needs.
Is GENEWIZ CLIA and CAP certified?
Yes, GENEWIZ offers clinical services through CLIA-certified and CAP-accredited laboratories that adhere to GLP standards and GCP standards where applicable. This includes regulated Olink® proteomics services, which are conducted in compliance with applicable regulatory requirements for use in clinical research and biomarker discovery. Our regulated Olink® workflow supports high-quality, reproducible data generation for projects that require strict quality oversight.
