Featured Synthetic DNA Libraries

1. Alanine Scanning Library: Alanine scanning is a widely-used approach that involves substituting non-alanine residues sequentially with alanine within a customer-determined region by site-directed mutagenesis. Alanine is usually the preferred choice for a scanning library because substitution with alanine eliminates side-chain interactions while retaining the structural integrity of the protein because it is the smallest chiral amino acid. Cysteine scanning is another technique that researchers use for certain studies.

2. Combinatorial Library: A combinatorial library allows you to create a library of mutants by using different genetic elements in multiple combinations to determine the most beneficial combination. You can obtain a combinatorial library using traditional partially randomized (NNK/NNS) or completely randomized (NNN) approaches. To achieve even greater control over the amino acid distribution in your library, choose our trimer-controlled library solution to eliminate the introduction of unwanted codons and maximize the efficiency of downstream screening.

3. Randomized Library: A randomized mutant library will allow you to create random amino acid substitutions in a small user-defined region such as an ORF. These proteins can then be expressed and assayed for function to determine beneficial substitutions in protein engineering studies.

4. Site-directed Mutagenesis Library: In a site-directed mutagenesis library, a customer-determined amino acid position will be substituted sequentially with all the other 19 naturally-occurring amino acids to create a library of mutants. With this approach, you can use structural-functional analysis to examine the benefits or adverse effects of a particular amino acid substitution.

5. Truncation Library: A truncation library of mutants is created by trimming amino acids systematically from either the N- or C-terminus (or both), of a protein around a pre-defined core region. This allows you to identify the core region responsible for protein function.
