What are Peptide Screening Services? These are specialized contract research services offered by biotech companies and CROs (Contract Research Organizations) to discover, optimize, or validate peptide-based molecules for various applications. They provide the expertise, libraries, and high-throughput technologies to efficiently identify peptide hits from vast molecular collections. Core Types of Peptide Screening Services 1. Library-Based Screening This is the most common starting point for discovery. Synthetic Peptide Libraries: Collections of thousands to millions of chemically synthesized peptides. Positional Scanning Libraries: For epitope mapping or identifying key amino acid residues. Truncation & Alanine Scanning: To find the minimal active sequence and critical residues. Phage Display Libraries: The largest and most diverse format (up to 10^11 unique sequences). A library of bacteriophages, each displaying a unique peptide on its coat protein, is panned against a target (e.g., a protein, cell). mRNA/Ribosome Display Libraries: Cell-free systems that link the peptide to its encoding mRNA, allowing for even larger libraries and easier mutagenesis. 2. Functional & Application-Specific Screening Services are tailored to the desired peptide function: Target-Based Screening: Against purified proteins (e.g., enzymes, receptors, GPCRs, protein-protein interaction interfaces). Cell-Based Screening: For peptides that modulate cell signaling, internalize into cells (CPPs), or have antimicrobial (AMP) or anticancer activity. Antigen/Antibody Screening: For epitope mapping, vaccine development,…
Aptamer Characterization Services: Ensuring the Precision and Reliability of Your Aptamer Development At KMD Bioscience, we understand that discovering an aptamer is just the first step. The true journey to a successful diagnostic, therapeutic, or sensor application hinges on rigorous and comprehensive Aptamer Characterization. Our specialized characterization services are designed to transform your promising aptamer sequences into well-understood, reliable, and high-performance molecular tools. We provide the critical data and validation needed to advance your projects with confidence. Why is Aptamer Characterization Essential? Unlike traditional antibodies, aptamers offer unparalleled advantages in stability, manufacturability, and design flexibility. However, to fully leverage these benefits, thorough characterization is non-negotiable. It confirms that the selected aptamer not only binds but does so with the specificity, affinity, and functionality required for your specific application. Our services mitigate risk, save valuable time and resources, and provide the foundational data for regulatory submissions. Our Comprehensive Suite of Characterization Services We employ a multi-faceted approach, utilizing state-of-the-art biophysical and analytical techniques to profile every critical aspect of your aptamer. 1. Affinity & Binding Kinetics Analysis Precise measurement of the binding strength is fundamental. We determine the dissociation constant (K<sub>D</sub>) and analyze real-time interaction kinetics. Primary Platform: Biolayer Interferometry (BLI). This label-free…
Epitope Mapping (also called antibody epitope mapping) is the set of experimental and computational approaches used to identify the precise antigen features an antibody recognizes and binds—down to specific amino acids, structural patches, or even interaction “hot spots.” In immunology terms, the epitope is the binding site on the antigen, while the antibody’s complementary binding surface is the paratope. Knowing exactly where binding occurs is foundational for understanding immune recognition, improving biologics, and designing better diagnostics and vaccines. Why Epitope Mapping Matters (Beyond “It Binds”) Antibodies can bind the same antigen in very different ways. Two antibodies may both “hit” the same protein yet differ dramatically in neutralization strength, cross-reactivity, or tolerance to mutations. Epitope mapping turns binding into actionable knowledge, helping teams: Differentiate antibodies that otherwise look similar by affinity alone (e.g., classifying binding regions and overlap patterns). Explain potency and mechanism of action, especially when blocking a receptor site or preventing conformational changes. Reduce off-target risk by detecting binding to conserved motifs shared across proteins. Guide design decisions for vaccines and diagnostics by focusing on minimal, protective, or assay-relevant epitopes. Two Big Epitope Types: Linear vs Conformational A key concept for practical…
Protein–protein interactions (PPIs) are the “handshakes” that let proteins assemble into machines, relay signals, build cellular structures, and decide cell fate. Chemical biology approaches PPIs with a distinctive philosophy: instead of only observing interactions, it builds molecules that can measure, perturb, stabilize, or rewire them—often in living systems—so interaction networks become experimentally controllable rather than just describable. This article is a knowledge-oriented deep dive into how Chemical Biology studies PPIs, what the major experimental strategies are, and how to think clearly about interaction “truth” versus experimental artifacts. 1) Why PPIs are hard: the core scientific challenge Many PPIs are not like enzyme–substrate binding (deep pockets and rigid fits). Instead, a large fraction are: Interface-dominated: broad, shallow surfaces rather than a single pocket. Dynamic: transient contacts that appear only at certain times, locations, or cellular states. Context dependent: the same pair of proteins may interact in one cell type but not another, or only after a modification (phosphorylation, ubiquitination, etc.). So PPI science is less about “does A bind B?” and more about: When and where does A approach B? Is it direct binding or complex membership (A and B in the same assembly but not touching)?…
The One-Bead-One-Compound (OBOC) Library technique is a powerful combinatorial chemistry strategy used to generate vast molecular libraries for screening and discovery. By anchoring a single, unique compound onto each solid bead, researchers can rapidly explore structural diversity across peptides, peptidomimetics, small molecules, and other bioactive scaffolds. This method has become instrumental in drug discovery, diagnostics, biomolecular engineering, and materials science due to its scalability and efficiency. What Is an OBOC Library? An OBOC library is a collection of beads—typically made of resin or polymer—where each bead carries millions of copies of the same compound. The core idea is that every bead is a microreactor that produces one unique molecular variant. This allows researchers to screen thousands to millions of compounds simultaneously while maintaining clarity on bead-specific identities. The OBOC method was designed to overcome the limitations of traditional combinatorial chemistry, offering a route for high-throughput synthesis without the need for separate reaction vessels for each individual compound. How OBOC Libraries Are Constructed The construction of an OBOC library usually follows a split–mix synthesis approach: Starting Material Distribution Beads are split into multiple reaction vessels. Chemical Coupling Different building blocks (such as amino acids) are coupled to…
