Several kinds of the p53 transcripts in which their open reading frames (ORFs) were truncated (ranging from 101 to 765 bp) were identified in Marek's disease (MD)-derived tumor cell lines as well as avian leukosis- and reticuloendotheliosis-derived ones, detected by nested RT-PCR and subsequent
Construction and using of retrovirus vectors derived from the Moloney murine leukemia virus (MoMuLV) are described. These vectors, designated minimal vectors, contain the left and right long terminal repeats (LTRs), a binding site for proline tRNA, a polypurine tract (PPT), and a dominant marker for
OBJECTIVE
Marek's disease virus (MDV), GD06 strain, was isolated from healthy Three-Yellow chickens without MD vaccine. In this study, we characterized GD06 strain.
METHODS
Meq gene and repeat short region of GD06 strain were amplified and analyzed, and the serotype was determined by indirect
To obtain purified H and M antigens suitable as primary standards in the serological diagnosis of histoplasmosis by agar gel double-diffusion tests, H and M reactive components of histoplasmin were fractionated by column chromatography by using Sephadex G-100, Sephadex G-200, and diethylaminoethyl
