List of phages and their virion proteins, which are used for display

Vector phage	Phage virion proteins for fusion display	Copy number of display	Size of display shown
M13	gpVIII	≈2700	Small peptide (6–8 amino acids)
	gpIII	≈5	Large protein with reduced viability
T4	Soc	≈960	Large protein (up to 837 amino acids)
	Hoc	≈160	Protein (up to 183 amino acids)
T7	10A	≈415	Protein (40–50 amino acids)
	10B	≈1	Protein (up to 1200 amino acids)
Lambda (λ)	gpD	≈420	Large protein (1024 amino acids)

Data were taken from Smith (1985), Markland et al. (1991), Mikawa et al. (1996), Ren et al. (1996, 1997), Ren and Black (1998), Iwasaki et al. (2000), Savinov and Austin (2001), Sche et al. (2001), Gupta et al. (2003), Pacheco et al. (2006), and Li et al. (2007).

The above phages are used for presentation of displayed antigens to mammalian cells; the λ system was also developed as a DNA delivery platform to antigen-presenting cells (APC).
