Web摘要. We have constructed a helper cell line and vector system based on the Bryan high titer (BH) strain of Rous sarcoma virus (RSV). BH-RSV is a defective virus which lacks an env gene; however, if env is supplied in trans, it replicates to a very high titer. Like BH-RSV, the vector contains gag and pol genes and lacks an env gene. WebDec 2, 2024 · Certain thresholds of HI antibody titers have been shown to be associated … can creamed spinach be reheated
