Figure 1From: Site directed biotinylation of filamentous phage structural proteinsModification of fth1 vector for expression of peptides at the N-terminus of Protein 3. The fth1 vector containing a second recombinant protein 8 gene was further modified at the native protein 3 gene. Two asymmetric BstX 1 restriction sites were introduced between the codons of Ala1 and Glu2 of Protein 3. The BT was subsequently cloned into the BstX1 cloning cassette.Back to article page
