The structure of factor X (FX) gene was analyzed in five FX deficient pedigrees with four different variants of the disease, as well as in 50 normal subjects. Genomic DNA from the deficient patients and the normal controls was digested with 12 restriction endonucleases and hybridized with a FX cDNA probe. The results seemingly exclude gross gene deletions or rearrangements in the deficient pati...

Genomic DNA from five kindreds and two individuals with hereditary elliptocytosis [HE(4.1+)] and a partial deficiency of protein 4.1 [HE(4.1+)] was extracted and probed with a cDNA for protein 4.1. When using a fragment of the cDNA that encompassed the coding region of the gene, two restriction fragment length polymorphisms segregating with protein 4.1 deficiency were found in one kindred when ...

Southern blot analysis with a murine interferon-alpha2 (MuIFN-alpha2) cDNA probe revealed restriction fragment polymorphism of EcoRI- and HindIII-digested C57BL/6 and BALB/cDNA. The inheritance pattern of this polymorphism was examined using DNA from each of the seven recombinant inbred strains derived from C57BL/6 and BALB/c; the strain distribution pattern suggests linkage of INF-alpha genes ...

Two recombinant DNA clones, pMG286.2 and pMG301.1, were isolated from the partial genomic library of Mycoplasma gallisepticum strain S6. Recombinant M. gallisepticum specific fragments were used as probes in Southern hybridisation with 10 M. gallisepticum strains whose DNA was digested by EcoRI, HindIII, BglII, RsaI and BamHI. The 1.5 kb fragment pMG301.1 did not show polymorphism in hybridisat...

Source/Description: A 3.6 kb EcoRI fragment (lambda ABL3) containing portions of exons 7 and 8 and the intervening intron of the ABL oncogene was isolated from a chromosome 9-specific library (ATCC # LA09NS01) using a 1.7 kb Abelson murine leukemia virus probe (v-abl, ONCOR, Inc.). A single copy 1.8 kb BglII fragment (ABL3) was derived from the original lambda clone and detects the StuI RFLP. P...

The epigenetic phenomenon could play a role in the interaction between chromatin and DNA-binding enzymes, allowing us to consider an association between the phenomenon and gene rearrangement. The correlation between methylation status and rearrangement of the T-cell receptor (TCR) ~ chain gene in leukemia cells obtained from patients with acute myeloid leukemia (AML) was examined. All of the AM...

pasteurella multocida (p. multocida), a gram-negative facultative anaerobic bacterium, is a causative animal pathogen in porcine atrophic rhinitis and avian fowl cholera. the outer membrane of gram-negative bacteria contains of many different protein in very high copy numbers. one of the major outer membrane, the h proteins have functional as high immunogenicity and antigenicity. in this study...

The parasitic wasp, Diachasmimorpha longicaudata (Ashmead) (Hymenoptera: Braconidae), introduces an entomopoxvirus (DlEPV) into its Caribbean fruit fly host, Anastrepha suspensa (Loew) (Diptera: Tephritidae), during oviposition. DlEPV has a 250–300 kb unipartite dsDNA genome, that replicates in the cytoplasm of the host's hemocytes, and inhibits the host’s encapsulation response. The putative p...
