For all libraries but f3-6mer, the number of primary clones is also the number of different displayed peptides.
Each sequence starts at the N terminus of the coat protein (just after the signal peptidase cleavage site) and extends through the last randomized amino acid. X, randomized amino acids; A, C, D, or G, invariant amino acids.
Estimated number of copies of the peptide displayed per virion.
Host protein to which the displayed peptide is genetically fused: either pIII (5 subunits in a ring at one tip of the virion) or pVIII (3,900 subunits arranged to form the tubular covering of the virion).
