Cell Signaling Technology - custom conjugation

Custom Antibody Conjugation/Labeling Service

CST has 1,500+ ready-to-ship antibody conjugates for flow cytometry, immunofluorescence, high-content screening, and other immunoassays. Our direct conjugation experts can also build specific antibody-label combinations so you can sidestep the time sink and pitfalls that come with do-it-yourself kits.

Conjugated antibodies are analyzed using size exclusion chromatography to verify their physical integrity and ensure preparations are free of contaminants, such as antibody aggregates or fragments, that may interfere with your experiments. Testing in key applications using biologically relevant cell systems and controls is also available.

Stringent purification to remove free dye/label and antibody, optimization of bio-conjugation chemistries, and identification of optimal degree of labeling ensures the best signal-to-noise ratio and the highest quality product.

Order Guarantee
Antibody loss occurs during every conjugation and cleanup process. We account for varying labeling efficiencies, absorb the cost of any excess antibody required to manufacture your conjugate, and ensure you receive exactly the amount of antibody you requested.

Multiple tiered options are available to match your needs and budget – from basic antibody conjugation to full validation and stability testing.

Extensive technical support and consultation are provided by the same scientists who produce and validate our commercially available antibodies.

Basic conjugations typically ship within 10 days, complex conjugations may take 3-4 weeks.

Cell Signaling Technology - custom DIY kit vs. CST custom conjugation: Comparison of PE conjugation of Helios (D8W4X) XP® Rabbit mAb by flow cytometry using CST custom conjugation method (blue) or another company’s DIY conjugation kit (red), on both RL-7 (dashed lines), a low-expressing cell line, and Jurkat (solid lines), a high-expressing cell line. The calculated signal-to-noise ratio is also shown. Custom conjugation avoids DIY conjugation inefficiencies such as suboptimal labeling, interference with specificity, and/or destabilization/degradation that negatively affect antibody performance and decrease yields


Cell Signaling Technology - custom DOL service option for fluorophores: Conjugation to certain fluorescent dyes (Alexa Fluor® and Pacific Blue™) is optimized by DOL testing to identify the optimal antibody:dye molecular ratio, resulting in conjugates with maximum specific signal intensity. In the data shown, the DOL of 4.28 provides the most optimal signal-to-noise compared to higher DOLs.
Cell Signaling Technology - custom proteomics

Proteomics Analytical Services

Proteomics can help early discovery teams identify and validate drug targets, uncover the right biomarkers for pharmacology groups, and determine off-target effects and the mechanism of action during the development process. Not a proteomics expert? You don’t have to be. As an innovator in proteomics discovery for over 20 years and inventor of PTMScan® Technology, CST has the deep scientific expertise to take on your most complex proteomics projects.

Demystifying Proteomics
A limited number of genes can generate a tremendous level of complexity at the protein level due to processes such as alternative splicing and post-translational modification. PTMs are essential for many cellular functions like protein activity, subcellular localization, degradation, and protein-protein interactions. Proteomic methods that profile PTMs provide insight into both normal and disease-based biology otherwise not feasible at the genetic level.

Consultative Approach
To make sure results are meaningful and move your discovery forward, our scientists work with you to understand your goals and provide guidance on service options and experimental design.

On-Time Answers
Our fast, reliable timelines* for proteomics results give you the actionable information needed to make critical decisions quickly and keep projects on track.

Actionable Data and Analysis
Complex bioinformatic results are combined with expert analysis to deliver information-rich, easy to understand reports. So there’s no guesswork and you can confidently move on to next steps.

Comprehensive Coverage
CST provides services that cover the 20 most critical types of post-translational modifications (PTMs), with more in the pipeline.

* Specific project timelines will vary depending on the complexity and size of the service.

Even the smallest projects can generate big data in proteomics discovery. That’s why CST experts oversee your project from initial planning, determining sample requirements and experimental design, to interpretation of results. We’re invested in making sure you find that next big discovery.

PTMScan® Discovery Proteomics Services
PTMScan Discovery Proteomics Services can help identify and quantify thousands of even low abundance post- ranslational modification (PTM) sites in your sample, including:

• Phosphorylation
• Ubiquitination
• Acetylation
• Methylation
• SUMOylation
• Serine/Threonine phosphorylation
• Tyrosine phosphorylation


IMAC Service
Immobilized Metal Affinity Chromatography (IMAC) is another strategy for enriching phosphorylated peptides before liquid chromatography tandem mass spectrometry
(LC-MS/MS) analysis, and is a highly complementary technique to the antibody-based enrichment recommended for optimal coverage of the phosphoproteome. The service
quantitates Ser/Thr phosphorylation using IMAC enrichment and analysis, identifying thousands to tens of thousands of sites with minimal protein sample (<500 µg).

PTMScan Multi-Pathway Service
The PTMScan Multi-Pathway Service enables the identification and quantification of hundreds to thousands of critical signaling nodes across various pathways involved in cancer biology, immune cell signaling, metabolic disease, and more. CST scientists utilize multiplexed cocktails of site- and protein-specific antibodies with LC-MS/MS to cover all of these signaling nodes in a single run.

TMT Total Proteome Profiling Services
Total Proteome Profiling Services provide global profiling of protein abundance in cells and tissues using multiplexed sample labeling with Tandem Mass Tags (TMT) and LC-MS/MS*. Together these technologies deliver high-quality quantitative data on thousands of proteins, and enable greater depth of coverage in your proteomics-driven discovery, biomarker analysis, and mechanism-of action studies.

Cell Signaling Technology - custom proteomics

Membrane-Enriched Total Proteome Service
Much current research focuses on membrane/cell surface proteins, but traditional total proteome analysis identifies a relatively small number of these proteins due to competition from all other intracellular proteins in the samples. Proprietary methods developed by CST double the number of membrane proteins identified and quantified in a total proteome study, allowing for a more complete view of proteins on the cell surface.
We also offer access to an internally-generated, membrane-enriched total proteome dataset with over 350 tumor samples from a variety of indications, and over 80 normal tissue samples.

Cell Signaling Technology - custom proteomics

Membrane-Enriched Total Proteome Service broadly surveys tumor specimens, identifying and quantifying twice as many cell surface proteins.

* CST is an officially licensed provider of TMT services. Available for customers based in the US, UK and EU only.

Lot Reservations and Bulk Orders
