The efficacy of random primer-pair arrays compared to conventional RAPD method with a single decamer primer was evaluated using DNA from two species of Cucumis. The banding patterns of amplicons revealed enhanced utility of primer-pair arrays over conventional RAPDs, producing more bands and a higher degree of polymorphism, both at intra- and inter-specific levels. Amplification produced by bot...

Approximately 170 kilobase pairs (kb) of contiguous DNA sequences derived from bands 3A3,4 of the Drosophila melanogaster X chromosome have been isolated by molecular cloning. Sequences required for the wild-type expression of the zeste locus are located within a 6-kb fragment of this chromosomal region, as shown by phenotypic rescue of zeste mutants in P element-mediated germ-line transformati...

Modified PCR amplification and direct sequencing procedures for the double-stranded genomic DNA template are described. Advantages of the approach we describe are: background artifact bands previously observed using high-molecular-weight DNA as a template were eliminated by this protocol; no gel purification or subcloning of the PCR-amplified double-stranded fragment was required prior to direc...

Aims: To screen potato genotypes for salt tolerance using in vitro stress and moleulcar markers.
 Experimental Design: The experiment was arranged Completely Randomized Design (CRD) with three replications.
 Place of the Study: conducted at Molecular Biology Tissue Culture Laboratories, Institute Biotechnology Genetic Engineering, Bangabandhu Sheikh Mujibur Rahman Agricultural Univers...

AM-112 [(1'R,5R,6R)-3-(4-amino-1,1-dimethyl-butyl)-6-(1'-hydroxyethyl)oxapenem-3-carboxylate] is a novel oxapenem compound which possesses potent beta-lactamase-inhibitory properties. Fifty-percent inhibitory concentrations (IC(50)s) of AM-112 for class A enzymes were between 0.16 and 2.24 micro M for three enzymes, compared to IC(50)s of 0.008 to 0.12 micro M for clavulanic acid. Against class...

Three strongly coupled sequences have been established in 110,112Te up to high spins. They are interpreted in terms of deformed structures built on proton 1-particle–1-hole excitations that reach termination at I ∼ 40h̄. This is the first observation of smooth terminating dipole structures in this mass region. Lifetime measurements have allowed the extraction of experimental B(M1; I → I −1) and ...

BACKGROUND & OBJECTIVES Leptospirosis is a severe and complex zoonotic disease prevalent in many countries including India. Current leptospiral research is focussed on the identification of the outer membrane proteins (OMPs) of the organism that could be used in developing diagnostic assays for leptospirosis. METHODS The Leptospira interrogans serovar Canicola was grown in EMJH medium and the...
