Pepkio Bio Combinatorics Calculator

Evaluates biological combinatorial spaces using arbitrary-precision arithmetic to prevent integer overflow and precision truncation in high-throughput assay designs. The tool models dual-index sample multiplexing for sequencing libraries, degenerate PCR primer complexities with IUPAC ambiguity codes, error-correcting DNA barcode capacities under Hamming distance bounds, and cell culture coverage scaling for pooled CRISPR screens. A web interface enables interactive parameter exploration, while a Python library and command-line interface submit calculation payloads to the Pepkio Tools API for pipeline automation. Calculator algorithms execute on Pepkio servers; client packages submit input parameters and return structured result objects with permalinks.
