Ontrols have been included as described above. The synthesized cDNA was kept at C till further use. In addition, we applied a functional gene microarray technique, the GeoChip (Tu et al), containing probes for genes involved in the majority of significant biogeochemical nutrient cycles. For this study, we extracted information from the GeoChip for amoA genes (probes). We analyzed DNA samples from July and January by the GeoChip DNA was extracted from triplicate samples from every with the 3 forms of microbial mats. The DNA was purified making use of UltraClean DNA purification Kit (MoBio Laboratories, Inc Carlsbad, CA, USA) in order to accomplish the top quality vital for hybridization around the chip. The DNA quantity was measured applying the Nanodrop ND program. The procedures for DNA labeling and microarray hybridization followed previously Tasimelteon site established protocols (Wu et al). Briefly, ng DNA was labeled with fluorescent Cy dye by random priming and resuspended in hybridization resolution (formamide, SSC, of unlabeled herring sperm DNA (Promega, Madison, WI), and . SDS) and universal regular DNA (. pmol ) labeled with all the fluorescent Cy dye (Liang et al), denatured for min at C and maintained at C till loaded onto the microarray slides. Arrays have been hybridized on a MAUI Hybridization Station (Roche, South San Francisco, CA) for h at C. The hybridized microarrays were scanned by a ScanArray Express (Perkin Elmer, Wellesley, MA) at laser power and photomultiplier tube obtain.
