We're proud to release our new genetic systems design software to empower the next generation of Synthetic Biologists.

RBS Library Calculator

Pre-Sequence [?]
Pre-Sequence: enter a nucleotide sequence (5 to 20 bp) that appears before the ribosome binding site, using A/G/C/T/U. The Pre-Sequence is important when the ribosome binding site is less than 35 nucleotides long. (optional)
Protein Coding Sequence [?]
Protein Coding Sequence: enter a nucleotide sequence (at least 50 bp) that encodes a protein, using A/G/C/T/U. Begins with a start codon (ATG/GTG/TTG/CTG). (required)

Degenerate RBS Sequence [?]
Degenerate Ribosome Binding Site Sequence: enter a degenerate nucleotide sequence that defines a library of RBSs, using the 15 letter UIPAC degenerate nucleotide code: A/G/C/T/S/W/K/R/Y/M/D/B/H/V/N. S: G or C. W: A or T. K: G or T. R: A or G. Y: C or T. M: A or C. D: A, G, or T. B: C, G, or T. H: A, C, or T. V: A, C, or G. N: A, G, C, or T.

Organism or (16S rRNA) [?]
Organism or 16S rRNA sequence: choose a bacterial species by typing in the first 3 letters of its name and selecting it from the list. Alternatively, you may enter the last 9 nucleotides of the 16S rRNA, using A/G/C/T/U. (required)
(start typing)
