Characterization of a supercoil-dependent S1 sensitive site 5' to the Drosophila melanogaster hsp 26 gene. [PDF]

Nucleic Acids Research, 1986
We have analyzed the prominent supercoil-dependent S1 nuclease cleavage site 5' to hsp 26 in the plasmid 88B13, which contains 11.7 kilobases from the Drosophila locus 67B1. The double stranded cleavage product is generated by initial nicking on the purine strand, six preferred sites occurring between positions -96 and -90 (relative to the start of ...

Development and characterization of a recombinant infectious bronchitis virus expressing the ectodomain region of S1 gene of H120 strain

Applied Microbiology and Biotechnology, 2013
Infectious bronchitis (IB), caused by infectious bronchitis virus (IBV), is a highly contagious chicken disease, and can lead to serious economic losses in poultry enterprises. The continual introduction of new IBV serotypes requires alternative strategies for the production of timely and safe vaccines against the emergence of variants. Modification of
