Combinational Variant Library
All Twist libraries are NGS verified.
Yes, you can submit your own codon usage table; however, defined codon tables where only one codon is used per amino acid might result in the failure of certain variants when avoiding restriction sites and amino acid motifs.
Twist will provide a report that includes a table showing the percent distribution of each length.
Twist will provide a report to show the distribution of the variants within each domain.
Twist will provide a report that compares the expected ratio distribution of each amino acid with the observed ratio at each domain.
