Project description:Here silica column and bead based RNA isolation was performed. The two methods were compared using prime-seq to determine the effect of the RNA isolation method on gene expression quantification. This was tested for three different types of input samples, PBMCs, HEK293T cells and striatal mouse tissue to compare the RNA isolation over a range of inputs. For each sample and experimental condition 8 technical replicates were performed.

This was tested for three different types of input samples, PBMCs, HEK293T cells and striatal mouse tissue to compare the RNA isolation over a range of inputs. The RNA isolation was performed with either 1000 or 10000 cells input. For each sample and experimental condition 8 technical replicates were performed.
Project description:A prototype oligonucleotide microarray was designed to detect and identify viable bacterial species with the potential to grow of common beer spoilage microorganisms from the genera Lactobacillus, Megasphaera, Pediococcus and Pectinatus. Probes targeted the intergenic spacer regions (ISR) between 16S and 23S rRNA, which were amplified in a combination of reverse transcriptase (RT) and polymerase chain reaction (PCR) prior to hybridization. This method allows the detection and discrimination of single bacterial species in a complex sample. Furthermore, microarrays using oligonucleotide probes targeting the ISR allow the distinction between viable bacteria with the potential to grow and non-growing bacteria. The results demonstrate the feasibility of oligonucleotide microarrays as a contamination control in food industry for the detection and identification of spoilage microorganisms within mixed population.
