442–448. 1966.—Two ribonucleic acid (RNA) coliphages, MS-2 and Qβ, have been characterized physically and serologically. MS-2 has an
S
20, w
value of 79, a molecular weight of 3.6 × 10
6
, a density of 1.422, and
p
H 3.9 as its isoelectric point. Qβ has an
S
20, w
of 84, a molecular weight of 4.2 × 10
6
, a density of 1.439, and an isoelectric point at
p
H 5.3. One host (
Escherichia coli
A-19) permits a distinction between the two on the basis of a marked difference in plaque size. They are distinct immunochemically, no serological cross-reaction being detectable.
