The PEC-Linker RC+ generation reflects the latest advancements in catch-and-release methodologies (Figure 1). All three construction blocks are optimized and tailored to allow general applicability as well as reliable and highly efficient purification and modification experience for the user.
Figure 1. Molecular structure of the PEC-LInker RC+.
1. Remove the Boc protecting group during the acid treatment for cleavage from the SPPS resin. The activated amino-oxy function serves as the anchor to the activated filter material.
2. A Bromo-substituted para azido-benzyl carbamate acts a the cleavable unit and represents the heart of the PEC-Linker RC+. The construction enables a well-balanced stability behavior, depending on the pH of the medium: Reducing the azide to an amine sensitizes the linker to cleavage. However, the fracture does not occur at neutral pH enabling wash out of by-products formed during reduction. Finally, the treatment of the safety-release system with weak acids liberates the peptide through an acid-catalyzed 1,6-elimination.
3. The para-nitrophenol represents an ideal leaving group with precisely tuned reactivity and storage stability.
The general scheme of PEC purification by catch-and-release consists of six steps shown in Figure 2.
Figure 2. Detailed scheme of the PEC process using the PEC-Linker RC+.
1. Couple the PEC-Linker to the target peptide at the end of the solid-phase peptide synthesis (SPPS). Capping after each amino acid coupling cycle to ensures the selective coupling on the target full-length sequence.
2. Cleave the peptide from the SPPS resin using respective TFA-cocktails.
3. Precipitate and dissolve the peptide.
4. Immobilize through covalent capture ("Catch ") on the activated filter material in an oxime ligation.
5. The covalent capture allows the washing out of unbound substances such as truncated sequences and additionally enables you to modify the bound, unprotected peptide selectively.
6a. The subsequent reduction of the PEC-Linker sensitizes the system for-safety release of the peptide.
6b. Liberate the purified peptide via weak acidic induced 1,6-elimination and elution ("Release").
Aldehyde-modified agarose reflects the state-of-the-art solid-phase equipment for catch-and-release methodologies. We offer an optimized agarose material (Agarose100) with high stability, and a high loading capacity of 100 µmol per mL settled resin in our current kit products.

We point out that the use of Belyntic's kit products with different peptides can lead to very different results due to the peptides' physicochemical diversity. The purification or modification efficiency is also strongly dependent on the synthesis of the peptide itself as well as on the process factors during the use of Belyntic's PEC technology.
Accordingly, it is the responsibility of the user to evaluate the quality of the final product for the intended application. Please conduct suitable analysis and take appropriate measures for further processing and utilization, e.g., by additional purification using chromatographic methods.
Major synthesis requirements are:
- Synthesize peptides by Fmoc-chemistry on the solid phase
- Apply capping after each amino acid coupling step
- Suppress re-attachment of protecting groups using decent scavengers
- Avoid aldehyde/ketone contaminations in solvents during precipitation and analysis of crude material
The most important limitations for accessible peptide sequences and design using the PEC-Linker RC+ are:
- N-terminally modified peptides
- disulfides or azides
Please see the FAQ section for more examples of known weaknesses and sources of contamination according to the current knowledge of Belyntic.
“For the first time, the Belyntic PEC Kit enabled us to provide peptides that we couldn't purify before.”
Dr. Adrian Glas
Peptide Specialty Laboratories GmbH (PSL)
“[…] our collaboration has highlighted the potential of PEC in either single-step purification or as a pre-LC clean-up step for very complex crude peptide mixtures, making it a valuable addition to our toolbox. The flexible nature of the PEC purification method also provides an additional platform for more unusual peptide chemistry […]”
Dr. Gavin Noble
“With Belyntic's PEC technology, a set of 48 short peptides were rapidly provided, that we were able to use immediately for the development and validation of LC-MS/MS quantification methods. Their team was extremely helpful and responsive. They helped us move a novel project forward very quickly.”
Dr. Alex Kentsis

“The PEC linker is a significant new invention in peptide synthesis technology, and every peptide chemist can benefit from it. PEC enables all peptide-based biopharmaceutical businesses to considerably increase efficiency in terms of speed and cost of goods, and we expect it to become a standard method of art in peptide production technologies.”
Dr. Thomas Bruckdorfer (CSO & VP Business Development)
“Belyntic’s High-Throughput Kit allowed me to quickly and conveniently clean up 96 peptides from an array synthesis. This greatly improved the purity of my peptides, facilitating the generation of high-quality data from subsequent screening experiments.”
