DeCyder Has Been Discontinued. Here Is What to Use Instead.
If your lab still runs GE Healthcare’s DeCyder for 2D-DIGE analysis, you are working with software that has been discontinued for years and is no longer developed, patched, or supported. This page explains exactly what happened to DeCyder, why continuing to rely on it is a growing risk, and which actively supported software your lab should move to depending on the work you do.
What happened to DeCyder?
DeCyder 2-D Differential Analysis Software was developed and sold by GE Healthcare (the former Amersham Biosciences proteomics line, now part of Cytiva) as the dedicated analysis package for the Ettan DIGE system and its Cy2, Cy3, and Cy5 CyDye workflow.
GE Healthcare set the final order date for DeCyder as 30 September 2015. The product was withdrawn and no commitment was made to ongoing technical support beyond that point. In short, DeCyder reached end of life almost a decade ago.
Why staying on DeCyder is a risk
Unsupported analysis software is not just an inconvenience. For labs that depend on DeCyder for live work, the problems compound over time:
- No updates or bug fixes. Any unresolved analysis issue stays unresolved, permanently.
- No security patches. The software receives nothing, which is a flag for any IT or quality function.
- Operating system compatibility. As Windows moves on, older unmaintained software becomes harder to install and keep running, and there is no vendor to call when it breaks.
- Data integrity and compliance exposure. In a 21 CFR Part 11, EU Annex 11, or GMP environment, running discontinued software with no vendor support is difficult to defend during an audit. Validation status, audit trails, and supportability all come under scrutiny.
- Knowledge loss. When the last person who knew the DeCyder workflow leaves, there is no training, no documentation pipeline, and no support line to fall back on.
If your DeCyder data underpins regulated decisions or published results, the question is not whether to migrate, but when.
A word on Delta2D and other “alternatives”
When DeCyder was discontinued, the alternative most commonly pointed to was DECODON’s Delta2D. Before you migrate in that direction, check the current support status carefully. Publicly visible development and release activity for Delta2D appears to have stalled some years ago, so moving from one discontinued or dormant package to another simply repeats the problem you are trying to solve. The goal is to land on software that is actively developed, supported, and will still be here in five years.
Which software should replace DeCyder for your lab?
DeCyder was used for two quite different jobs. The right replacement depends on which one you do. Pick your path below.
Path 1: Differential protein expression and biomarker work (2D-DIGE, 2D-PAGE proteomics)
If you use DeCyder to find proteins that change in abundance between conditions, treated versus untreated, healthy versus diseased, time course studies, the direct replacement is SameSpots.
SameSpots is built specifically for differential expression analysis of 2D gels, 2D-DIGE, 2D Western blots, and 2D-DIBE, all in a single license with no add-on modules. It addresses the exact weaknesses DeCyder users know well:
- 100% spot matching with no missing values. SameSpots aligns all images into a shared coordinate space first, then detects one spot pattern and propagates it to every image. That means a complete, unbroken dataset for valid statistics, rather than the gaps and manual spot matching that slow DeCyder analysis down.
- Built-in statistics. One-way, two-way, and repeated measures ANOVA, PCA, q-values, and fold change are included, so you go from images to answers in the same package.
- Speed. Typical analysis runs at around five minutes per gel, and most users are fully trained within a couple of hours.
- Independently validated against DeCyder. A peer-reviewed head-to-head comparison, What’s the Difference? 2D-DIGE Image Analysis by DeCyder versus SameSpots, found SameSpots delivered faster, more reproducible abundance results by aligning before detecting, avoiding DeCyder’s time-consuming spot matching.
- Compliance ready. Paired with TotalLab’s AuditSafe module, SameSpots meets full 21 CFR Part 11 and EU Annex 11 requirements.
SameSpots is trusted for differential expression and DIGE work by leading pharmaceutical, biotech, and academic labs including AstraZeneca, Roche, and the NIH. There is precedent for this kind of migration too: when Bio-Rad discontinued its PDQuest software, it reviewed the options and pointed its users to SameSpots. You can read about that in our PDQuest discontinued guide.

Path 2: Host cell protein (HCP) antibody coverage analysis
If you use, or used, DeCyder and 2D-DIGE to assess anti-HCP antibody coverage for ELISA validation and bioprocess work, the purpose-built replacement is SpotMap 2D.
SpotMap 2D was designed from the ground up to calculate HCP antibody coverage rather than being repurposed proteomics software. It is the better fit when coverage percentage, not differential expression, is the question:
- Automated coverage scoring in around 10 minutes, by spot number or spot volume.
- Full support for 2D-PAGE, 2D Western blot, 2D-DIGE, 2D-DIBE, and immunoaffinity chromatography workflows.
- Automatic quadrant analysis to show antibody performance across molecular weight and isoelectric point ranges.
- Vendor neutral, supporting effectively any scanner or imager and all common image formats.
- Officially recommended by Merck for use with their Auto2D devices, and 21 CFR Part 11 ready via AuditSafe.
Moving off DeCyder is easier than staying on it
You do not need to commit before you have seen it work on your own data. Download a free trial of SameSpots or SpotMap 2D and run it against the same images you analyze in DeCyder today, so you can compare results and timings directly. Our scientific support team will walk you through the workflow using a dataset representative of your experiments.
If you would rather talk it through first, book a free demo and we will show you the migration path for your specific setup.
Frequently asked questions
Is DeCyder still supported? No. GE Healthcare discontinued DeCyder, with a final order date of 30 September 2015, and did not commit to ongoing technical support beyond that point. It receives no updates, bug fixes, or security patches.
When was DeCyder discontinued? DeCyder’s last order date was 30 September 2015. It was withdrawn and never replaced with an equivalent product by the original vendor.
What can I use instead of DeCyder? For differential protein expression and 2D-DIGE proteomics, use SameSpots, the actively developed, peer-reviewed alternative that delivers 100% spot matching with no missing values. For anti-HCP antibody coverage analysis, use SpotMap 2D, which is purpose-built for coverage scoring. Both offer free trials.
Can I still run DeCyder on Windows 10 or Windows 11? Some labs continue to run older DeCyder installations, but because the software is unmaintained there is no vendor support if it fails on a newer operating system, and no guarantee of future compatibility. This is a key reason labs migrate to actively supported software.
Is it safe to keep using DeCyder in a GMP or 21 CFR Part 11 lab? Running discontinued, unsupported software in a regulated environment is difficult to justify during an audit, because there are no updates, no patches, and no vendor support behind your validated system. SameSpots and SpotMap 2D both reach full 21 CFR Part 11 and EU Annex 11 compliance when used with TotalLab’s AuditSafe module.
What is the best DeCyder alternative for 2D-DIGE? SameSpots is the most direct replacement for DeCyder’s 2D-DIGE workflow. It supports DIGE with Cy2, Cy3, and Cy5 dyes and a pooled internal standard, includes DIGE support in the standard license with no extra module, and has been independently compared against DeCyder in a peer-reviewed study.
Can I analyze my existing DIGE images in SameSpots? Yes. SameSpots is vendor neutral and reads all common image formats, so you can load the same images you currently analyze in DeCyder. The best way to confirm the fit is to run a free trial on your own data.
