Proteomics Frequently Asked Questions

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.

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.

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.

Not currently; FFPE preservation degrades proteins and is not compatible with PEA technology.

Our team prioritizes fast turnaround times and provides a timeline based on first-pass processing. The turnaround time listed within the quote is inclusive of all steps quoted, unless otherwise noted. If repeat processing is required, the turnaround may be subject to change and will be proactively communicated to the client.

If the scope of a project changes after project initiation or if sample or project clarification is required after sample receipt, GENEWIZ may reassess the turnaround time based on the subsequent communications and modifications (if applicable).

All extraction kits and reagents are routinely updated to remain best-in-class. If you are seeking access to previous versions of our method, please submit an inquiry (availability is assessed on a case-by-case basis).

Extractions are performed to the best of our ability, and we are unable to guarantee yield due to multiple variables that may affect sample yield and quality. Costs to cover the work performed will be applied, regardless of the outcome.

All preparation kits and reagents are routinely updated to remain best-in-class. If you are seeking access to previous versions of our method, please submit an inquiry (availability is assessed on a case-by-case basis).

For most of the services, an initial sample QC is included within the fee of the project for all samples that will proceed to the next processing stage (e.g. library preparation or sequencing) unless otherwise noted within the quotation. Resubmissions or additional, optional samples may incur a nominal fee for QC.

Initial sample QC can include:

• Assessing RNA concentration and integrity
• Assessing DNA concentration and DNA size (for select projects)
• Assessing premade library size and concentration
• Assessing cryopreserved cells by cell count and viability

The sequencing platform will be listed within the Service Description of the quotation.

Unless specifically noted in the quotation, GENEWIZ reserves the right to choose between equivalent instruments depending on the target read depth and configuration requested. If a specific instrument is required, please add special comments in your quote/order and notify the GENEWIZ NGS team prior to project initiation.

Illumina-based projects

Only applicable for samples that pass QC and libraries prepared at GENEWIZ:

Data Quality

• NovaSeq 2x150bp: ≥85% of bases ≥Q30
• NovaSeq 2x250bp: ≥80% of bases ≥Q30
• MiSeq 2x150bp: ≥80% of bases ≥Q30
• MiSeq 2x250bp: ≥75% of bases ≥Q30

Data Yield

• Within 10% of total data target yield per lane or flowcell, unless otherwise noted
• Within 20% of per sample target yield, unless otherwise noted

Quality and yield for samples that do not pass QC and are processed at best effort are not guaranteed. Premade libraries/library pools submitted for sequencing only quality and yield are evaluated on a case-by-case basis.

Multiplexing is performed to the best of our ability to ensure relatively even data distribution amongst samples.

Due to the possible wide range of performance being influenced by sequence complexity and sample quality, GENEWIZ does not guarantee average coverage or on-target specificity for each sample. We can instead recommend target data output that would increase the chances of obtaining the desired coverage based on the sample and library type utilized.

Data analysis is performed to the best of our ability and results are not guaranteed for samples or libraries not passing QC or do not fit the analysis pipeline’s criteria.

Yes, we can recommend the best data delivery option based on the platform and project details. Options include:

• Secure File Transfer Protocol (sFTP) - additional charges may apply
• Customer Cloud Account - AWS, Microsoft Azure, Google Cloud
• Hard Drive - additional charges may apply

Delivery to most customer cloud solutions is free of charge. If you have any questions, please submit an inquiry.

By default, results are sent via a secure File Transfer Protocol (sFTP). Please refer to our sFTP Data Download Guide for instructions on how to download your data and troubleshooting tips. Additional charges may be applicable for large data transfers.

Please refer to the delivery email sent from GENEWIZ for detailed information on the transfer and consult with your IT department to ensure compliance with your institution’s policies.

We take data security very seriously and we make every attempt to keep your data private and protected. The data transfer we offer is secure; however, should you desire an alternative delivery method, we are happy to work with you.

We hold any remaining samples for up to 3 months after project completion. Clinical samples processed in our Regulatory-Environment or CLIA-licensed laboratory may have longer sample storage timelines. Please contact us if you would like samples retained for a longer period or shipped back to you.

GENEWIZ offers raw data storage (i.e. FASTQ for Illumina, BAM for PacBio, POD5 for Oxford Nanopore) for up to 6 months after project completion. Data generated for samples processed in the Regulatory-Environment or CLIA-licensed laboratory may have longer data retention timelines. Please contact us if you would like the data to be retained for a longer period.

View our Sample Submission Guidelines for instructions on preparing and sending samples. Organize your samples in tubes or plates following the order indicated on the sample submission form.

• Tubes: Prepare samples in clearly labeled and well-organized 1.5 mL flip-cap microcentrifuge tubes. Please avoid using Parafilm to seal the tubes.

Unless otherwise instructed, GENEWIZ reserves the right to combine multiple vials of the same sample for extraction and/or library preparation.

• Plates: For projects with 16 or more samples, prepare samples in clearly labeled, securely sealed 96-well full-skirted PCR v-bottom plates. Arrange the samples vertically by column (i.e. A1, B1, C1, etc.)
