Project description:The plasma proteome of sparrows from the Atacama desert was identified using bottom up proteomics by online nanoLC tandem mass spectrometry. Seasonal and geographic effects on the plasma proteome were investigated. All experiments and sample collections were performed by the team of Dr. Paulina Gonzalez-Gomez. Proteomics sample preparation and biological mass spectrometry were performed in the laboratory of Prof. Dietmar Kueltz at UC Davis
Project description:Conditions of low organic matter content per gram of soil in the hyperarid core of the Atacama Desert, extreme temperatures and high UV radiation, makes it one of the best terrestrial analogue of Mars and one of the best scenarios for testing instrumentation devoted to in situ planetary exploration. We have remotely and automatically operated the SOLID-LDChip, an antibody microarray-based sensor instrument, as part of a rover payload during the 2019 NASA’s ASTEP ARADS Mars drilling simulating campaign. SOLID was loaded with a robotic arm with samples collected down to 80 cm depth and, after sample analysis with LDChip, sent results to a remote science team, to be validated by “omics” techniques.
