Evaluation of cDNA microarray data by multiple clones mapping to the same transcript.

A microarray-based method for the parallel analysis of genotypes and expression profiles of wood-forming tissues in Eucalyptus grandis

BACKGROUND Fast-growing Eucalyptus grandis trees are one of the most efficient producers of wood in South Africa. The most serious problem affecting the quality and yield of solid wood products is the occurrence of end splitting in logs. Selection of E. grandis planting stock that exhibit preferred wood qualities is thus a priority of the South African forestry industry. We used microarray-base...

Combined transcript and metabolite analysis reveals genes involved in spider mite induced volatile formation in cucumber plants.

Many plants have an indirect defense against herbivores by emitting volatiles that attract carnivorous enemies of the herbivores. In cucumber (Cucumis sativus) the production of carnivore attractants can be induced by herbivory or jasmonic acid spraying. From the leaves of cucumber plants with and without spider mite infestation, two subtractive cDNA libraries were made that were enriched in cD...

Analysis of repeatability in spotted cDNA microarrays.

We report a strategy for analysis of data quality in cDNA microarrays based on the repeatability of repeatedly spotted clones. We describe how repeatability can be used to control data quality by developing adaptive filtering criteria for microarray data containing clones spotted in multiple spots. We have applied the method on five publicly available cDNA microarray data sets and one previousl...

CLONING AND SEQUENCING OF A MITOCHONDRIAL AUTOANTIGEN WITH IMMUNOGLOBULIN G FROM PATIENTS WITH MULTIPLE SCLEROSIS

Multiple Sclerosis (MS) is a chronic neurological disease of the central nervous system (CNS), characterised by a cellular immune response in early stages and demyelination of the CNS later. Although the cause of MS is unknown, there is much evidence that points to MS as an autoimmune disease. To test the hypotheses that an Autoantigen is involved in MS, we screened a ?gt11 human foetal spinal ...
