alcanivorax borkumensis is a marine bacterium that has ability to grow on limited substrates that mainly is alkanes. the ability to use wide range of hydrocarbons is advantage of this bacterium to other marine community bacteria. a. borkumensis have two genetic systems for alkane biodegradation. the first system is alkane hydroxylase (alk-b1and alk-b2) and the second system is cytochrome p450....
human growth hormone (hgh) genomic sequence containing 5 exons and 4 introns was cloned in pcdna-3 and the constructed plasmid was subsequently used for transfection ofnlli-3t3 cell line using lipofection technique. expression of hgh in stably transfected cells was assayed using elisa. total rna was extracted from transfected cells and hgh cdna was amplified by rt-pcr using specific primers. th...
We have examined the morphology, cytochemistry, and biochemistry of mouse leukocyte subsets by analyzing cloned leukocyte populations specialized to perform different immunologic functions. Cloned cells expressing high-affinity plasma membrane receptors for IgE and mediating natural killer (NK) lysis and cloned antigen-specific suppressor T cells contained prominent osmiophilic cytoplasmic gran...
The lignans of Eucommia ulmoides have been extensively studied and shown to a dual mechanism regulating blood pressure. Studies that DIR1 is key gene in the biosynthetic pathway Oliv. In this study, 2000 bp upstream promoter sequence was cloned, part (1495 bp) its 5′-end truncated segment were constructed into pCAMBIA1391Z expression plasmid ß-glucuronidase (GUS). Agrobacterium-mediated genetic...
For more than ten years, reproductive biotechnologies using somatic cell nuclear transfer have made possible the production of cloned animals in various domestic and laboratory species. The influence of the cloning process on offspring characteristics has been studied in various developmental aspects, however, it has not yet been documented in detail for behavioral traits. Behavioral studies of...
