[Use of the cation detergent, cetyltrimethylammonium bromide, in isolating the RNA of the influenza virus].

Isolation of virion RNA of influenza virus by the SDS-phenol method from subviral particles obtained from purified virions by treating them with a cation detergent, cetyl-methyl-ammonium bromide, increased RNA yields approximately 2-fold as compared with isolation of this RNA from whole virions.
