Construction of a fosmid library with environmental genomic DNA isolated from the vertical depth continuum of a seasonally hypoxic fjord is described. The resulting clone library is picked into 384-well plates and archived for downstream sequencing and functional screening by the application of an automated colony picking system.

Peptide tertiary amides (PTAs) are a superfamily of peptidomimetics that include but are not limited to peptides, peptoids and N-methylated peptides. Here we describe a synthetic method which combines both split-and-pool and sub-monomer strategies to synthesize a one-bead one-compound library of PTAs.

SELEX protocols comprise multiple rounds of selection, each of which require regeneration of bound ligands, which in turn require fixed primer sequences flanking the random library regions. These fixed primer sequences can interfere with the selection process (false positives and negatives). Here we present a primer-free protocol.

Zebrafish has emerged as a powerful in vivo platform for phenotype-based drug screens and chemical genetic analysis. Here, we demonstrate a simple, practical method for large-scale screening of small molecules using zebrafish embryos.
FAQs
Library design determines what biological question the collection can address. A diverse library samples many chemical structures, whereas a focused library concentrates on compounds selected for a particular research question. This distinction affects the range of structures tested and the likelihood that screening will reveal modulators relevant to a target, enzyme, receptor, or cellular process.
Screening outcomes depend on the biological system chosen. Purified targets, enzymes, and receptors allow investigators to examine direct molecular interactions or changes in activity, while living cells reveal effects within a cellular context. Comparing these formats can help connect a compound’s observed activity with a specific molecular target or a broader cellular response.
Chemical structure becomes especially informative after an initial hit is found. Follow-up testing compares compounds and their biological activities, linking structural differences to changes in function. This structure-activity analysis helps distinguish promising modulators from weaker candidates and provides a basis for deciding which molecules should advance toward further optimization.
An effective workflow moves from collection design to compound testing and then to confirmation. Researchers assemble compounds through chemical synthesis, parallel diversification, or selection, screen them against the chosen target or cells, and identify active molecules. Subsequent testing examines initial hits more closely before the most informative compounds are prioritized for optimization.
When the goal is broad discovery, a diverse Small Molecule Library can survey many structural possibilities in one screening effort. A focused collection is more appropriate when the research question calls for compounds selected around a particular biological context. Choosing between these formats helps align screening scope with target validation, pathway analysis, or early drug-discovery objectives.
Screening results can support more than finding a compound that changes activity. Active molecules may help validate whether a target contributes to a process, probe pathway behavior, or identify starting points for early drug discovery. Interpretation is strongest when initial activity is followed by testing that relates chemical structure to biological effect and guides compound prioritization.
