Which Kind of Phage Vectors are Most Frequently Used in Phage

Question

Which kind of phage vectors are most frequently used in phage display technology?
A) double-stranded DNA T-odd
B) double-stranded DNA T-even
C) filamentous single-stranded DNA phages
D) lambda-based vectors
E) alpha-based vectors

Accepted Answer

Filamentous single-stranded DNA phages, such as M13 and fd, are the most frequently used phage vectors in phage display technology. These phages allow for the display of peptides or proteins on their surface, which can be used for applications such as identifying ligands or antibodies that bind to a specific target. Other phage vectors such as T-odd and lambda-based have also been used, but not as frequently as filamentous phages.
