Mutant Library Construction Service

Our Mutant Library Service Includes:

1. Site-directed Mutagenesis Libraries 
CD Genomics combines its expertise in de novo gene synthesis and site-directed mutagenesis into an excellent site-directed mutagenesis library construction service. The site-directed mutagenesis library offers a great platform for protein function and active center studies. In these libraries, any given residue can be substituted with any of other 19 common amino acids, creating systematic combinations of amino acid mutations that reveal any significant pattern.

2. Scanning Point Mutation Libraries  
Scanning point mutation is a systematic means of improving protein performance. It outperforms standard alanine/cysteine scanning by replacing each amino acid with all 20 amino acids simultaneously. This technique provides a detailed profile of each amino acid at the position. For each codon of interest, a small, site-saturated library is constructed. This library can be delivered as a pool or in a separated format for any substitution variant (19 in total). The application of CD Genomics's expertise in de novogene synthesis to the field of sequential permutation scanning allows us to provide superb sequential permutation scanning library construction services.

3. Randomized and Degenerated Libraries 
With our advanced degenerated oligonucleotide techniques, CD Genomics can generate any form of randomization or degeneration of full-length gene in a synthetic DNA fragment. This permits controlled, highly precise randomization within oligonucleotides. CD Genomics's in vitro library synthesis technology can introduce random substitutions on a controlled level with maximum flexibility. The mutation frequency can be set to any value between 1 and 20 mutations per kb. A peer group of 48, 96, or 192 individual transformants is sequence-verified.
