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,…
Peptides sit in a sweet spot between small molecules and biologics: they can be engineered for high specificity, tuned with chemical modifications, and explored rapidly through libraries. But peptide screening is not “just HTS with different molecules.” It blends chemistry (library design and synthesis), biology (assay selection and target context), and analytics (MS-based confirmation, binding kinetics, stability, and sometimes regulated bioanalysis). That is why many teams partner with a Contract Research Organization (CRO) for Peptide Screening—to industrialize the workflow from idea → hits → optimized leads, while keeping data quality, reproducibility, and documentation strong. Below is a knowledge-focused overview of what peptide-screening CROs typically do, the major screening technologies, the deliverables you should expect, and the technical “gotchas” that often decide whether a campaign succeeds. 1) What a “CRO for Peptide Screening” actually provides (beyond bench capacity) A peptide-screening CRO usually covers some combination of these pillars: Library strategy + synthesis execution Peptide discovery begins with what you choose to search. Many CROs help design libraries for the biological question (agonist vs antagonist, surface binder vs enzyme substrate, linear vs cyclic peptides, inclusion of non-natural amino acids, etc.), then manufacture the library and track identities and…
SPOT Synthesis (often written as SPOT peptide synthesis or SPOT synthesis technique) is a positionally addressable, parallel solid-phase peptide synthesis method where many peptides are built simultaneously as discrete “spots” on a derivatized cellulose membrane. Instead of synthesizing one peptide at a time on resin beads, SPOT Synthesis dispenses activated amino acid solutions onto predefined membrane coordinates, enabling rapid generation of peptide libraries and arrays for downstream screening.  ⸻ What Makes SPOT Synthesis Unique? 1) Parallel synthesis on a planar cellulose support In SPOT Synthesis, the membrane acts as a flat solid support. Each printed droplet is absorbed into the porous cellulose and behaves like a tiny reaction “micro-compartment,” allowing hundreds to thousands of peptides to be synthesized in parallel on one sheet.  2) Addressable peptide libraries (arrays you can map by position) Every spot corresponds to a known sequence (or sequence mixture), which makes SPOT arrays especially useful when you need systematic coverage—such as scanning a protein sequence with overlapping peptides or exploring sequence–activity relationships.  3) Scale and throughput The method is widely described as supporting very high spot counts (from hundreds up to many thousands, depending on format and spot size). This density makes it…
A peptide library is one of the most powerful resources in molecular biology, drug discovery, and biochemical research. It consists of a large collection of peptides—each with distinct sequences—designed to probe biological targets, identify binding interactions, and accelerate the discovery of functional molecules. As scientific research and pharmaceutical innovation increasingly rely on high-throughput techniques, peptide libraries have become central to understanding protein interactions, enzyme specificity, and therapeutic candidate selection. ⸻ What Is a Peptide Library? A peptide library is a structured set of diverse peptides with systematically varied amino-acid sequences. These peptides are synthesized or expressed in large numbers to explore how different sequences interact with a biological target. Because proteins and enzymes recognize molecules based on their structure and sequence, peptide libraries provide a versatile platform to map these interactions efficiently. Unlike single-peptide investigations, libraries allow the simultaneous evaluation of thousands to millions of peptide variants. This significantly reduces the time required to identify high-affinity binders, active sequences, or inhibitory motifs. ⸻ How Peptide Libraries Are Constructed 1. Solid-Phase Peptide Synthesis (SPPS) Most artificial peptide libraries rely on SPPS, which builds peptides one amino acid at a time. By varying the added amino acids in each step, researchers generate…
