Your page says that BHK-21 cells do not have reverse transcriptase activity, but this is incorrect according to Lovatt et al. (J. Virol. Methods 1999 82(2):185-200). Also, like CHO cells, BHK-21 cells express intra-cisternal type A particles, and possibly other retroviral particles as seen on TEM(Bernhard and Tournier, Ann Inst Pasteur 1964 107:447-52, Compans et al.,Virology, 1966, 30:411-26, Lasneret et al., J Exp. Pathol. 1989 4:47-56, McGee-Russell et al. 1965, Proc. of 3rd European Regional Conf. on Electron Microscopy, pp. 367-68, Wang and Mulligan, J. Virol. 1999 73:8917.). Please correct or cite the evidence for lack of RT activity, in contradiction to the expression of retroviral particles and positive PERT signals from retroviral RT by Lovatt et al.
