P2A
Part Description
2A self-cleaving peptides is a class of 18–22 aa long peptides that can induce ribosomal skipping during translation of a protein in a cell.
Usage
Characterization
P2A have been shown to have superior cleavage ability when compared to different 2A peptide.
Improvements
by Inserting GSG and SGS linkers, V5 epitope tag (GKPUPNPLLGLDST) and 3xFlag epitope tag immediately preceding 2A has been shown to improve 2A cleavage efficiency
