Overview Post-translational Modification Backbone Alteration Custom Labeling and Conjugation Service Workflow Why Choose Us?

Veterinary therapeutic peptides often face limitations in clinical settings, and optimizing their structures can significantly enhance their properties before clinical trials commence. From post-translational modifications, and backbone alteration, to custom labeling, BioVenic employs state-of-the-art technologies and a variety of techniques to refine these peptides for animal use. Our methods are aimed at improving peptide structures to enhance their functionality, stability, activity, and other critical properties, thereby meeting specific biological requirements or enhancing pharmacological effects. We are committed to assisting our clients in developing innovative, peptide-based therapies that are specifically tailored to advance animal health.

Peptide Structure Optimization Overview

The veterinary therapeutic peptide structure optimization services at BioVenic offer a diverse range of methods designed to meet all preclinical research requirements. These techniques enhance peptide stability, modify structures for improved understanding of biological functions, and boost immunogenicity for both the discovery and production phases. Our services extend beyond basic modifications; we offer various terminus and internal alterations, as well as peptide labeling and backbone modifications, to support advanced imaging and detection needs.

Peptide Post-translational Modification

Peptide modification involves the artificial addition of molecules to peptides to enhance their functionality or specificity. BioVenic now offers an expanded range of expertise in veterinary therapeutic peptide modifications. Our team views these modifications as effective solutions for improving the function and stability of therapeutic peptides for animal use. We are equipped to assist our customers in achieving scientific excellence with a variety of modifications, including acylation, amidation, biotinylation, cyclization, alkylation, lipidation, PEGylation, phosphorylation, and the coupling of bifunctional chelating agents and prosthetic groups for imaging.

Peptide Backbone Alteration

BioVenic's peptide backbone alteration services offer innovative approaches to peptide modification that go beyond traditional N- and C-terminal modifications. Unlike terminal modifications that typically involve adding functional groups to the ends of peptide chains, backbone alterations involve changes to the peptide's central structure itself. This includes the alteration of amino acids and peptide bonds within the chain, providing enhanced biological properties and stability. These innovative modifications not only improve the therapeutic properties of peptides but also expand their potential applications in veterinary medicine. By offering such specialized services, BioVenic is at the forefront of advancing peptide-based therapy development before clinical application, ensuring clients receive tailored solutions that meet specific preclinical research and therapeutic needs. Our services specifically include:

Backbone Alteration	Description
Hydroxy Ethylene Isosteres, Thioethers, Reduced Peptide Bonds, Retro-inverso Peptides	These modifications introduce alternative chemical structures such as hydroxy ethylene isosteres and thioethers to mimic natural peptide bonds while enhancing protease resistance and metabolic stability. Retro-inverso peptides, where the sequence is reversed and configured in D-amino acids, improve stability and receptor selectivity.
Depsipeptides	Depsipeptides feature ester linkages instead of amide bonds in the peptide backbone, enhancing the compound's resistance to enzymatic degradation and changing its pharmacokinetic properties, which can be beneficial in drug design.
Incorporation of Unusual Amino Acids, D-enantiomers, α- and N-methylamino Acids	This involves substituting standard L-amino acids with unusual amino acids or D-enantiomers to modify the peptide's conformation and interaction with biological targets. Incorporation of α- and N-methyl amino acids restricts the flexibility of the peptide chain, potentially increasing its specificity and resistance to enzymatic cleavage.

Custom Labeling and Conjugation

Our custom labeling and conjugation services are central to optimizing the structure and enhancing the functional properties of peptides for therapeutic and research applications. This suite of advanced techniques is designed to modify veterinary therapeutic peptides at a molecular level, improving their stability, activity, and specificity, which are critical for successful preclinical and experimental outcomes. It not only addresses the fundamental challenges in peptide therapeutics but also propels forward the development of highly specific, stable, and effective peptide-based therapies. Our services specifically include:

Labeling/Conjugation	Description
Heavy Isotope Labeling (15N, 13C)	This technique involves incorporating stable isotopes of nitrogen (15N) and carbon (13C) into peptides, which is useful for detailed structural and functional analysis through techniques such as NMR spectroscopy.
Conjugation to a Carrier Protein	This method attaches peptides to carrier proteins to enhance immunogenicity, improve peptide stability, and facilitate better delivery and recognition in biological assays.
FRET Substrates with Fluorophore/quencher Pairs	Fluorescence resonance energy transfer (FRET) substrates are designed with specific fluorophore and quencher pairs that enable the study of peptide interactions and dynamics by monitoring energy transfer upon enzymatic cleavage.
Peptide-DNA Conjugation	This modification connects peptides to DNA molecules, allowing for the targeted delivery of peptides and the exploration of gene delivery mechanisms or the development of novel therapeutics.
Peptide-RNA Conjugation	Similar to peptide-DNA conjugation, this technique links peptides to RNA, facilitating targeted therapeutic applications, including RNA interference and vaccine development.
Peptide-enzyme Labeling	This process involves labeling peptides with enzymes to enhance visibility and tracking in biochemical assays, improving the quantification and detection of peptide activity.
