SeqBench

SeqBench is a browser-based workbench of 82 tools for molecular cloning, primer design and sequence analysis: nearest-neighbour melting temperature, oligo dimer and hairpin screening, in-silico PCR, site-directed mutagenesis, restriction mapping, Gibson, Golden Gate and restriction-ligation assembly simulation, plasmid annotation and backbone identification, CRISPR gRNA, HDR donor and base editing design, codon optimisation and CAI, pairwise and multiple alignment, RNA secondary structure, protein properties, Sanger ab1 traces, HGVS conversion and variant annotation. It verifies constructs as well as designing them: re-deriving an assembly from its stated parts and diffing it against the claimed product, aligning sequencing reads back onto a claimed reference, and scoring Golden Gate overhang sets against published ligation-fidelity data. Batch FASTA processing, multi-tool workflows, a conversational tool-calling interface (SeqBench-GPT), a REST API and an MCP server are included.
