"We believe that the C ring has been continuously polluted by meteoroid bombardment since it first formed, and we think the middle C ring was further contaminated by an incoming Centaur, a rocky object torn apart by tides and ultimately broken into pieces and injected into the C ring," said Zhang, who grew up in Shanghai, China, and earned an undergraduate degree at Peking University.
Ultimate cell-based therapy will require that the various types of retinal cells will need to be further purified from contaminating cell populations.
OPCs were further purified from contaminating microglia by a differential adhesion step.
Metagenomic data from HCH contaminated pond sediment and similar HCH contaminated sites were further used to analyze the pan-genome dynamics of Pseudomonas genotypes enriched across increasing HCH gradient.
RepeatMasker (http://ftp.genome.washington.edu/) was used to mask repeated sequences, and the masked sequences were further screened to remove contaminating sequences from bacteria and viruses using BLASTN [106].
RepeatMasker [ 27] was used to mask repeated sequences, and the masked sequences were further screened to remove contaminating sequences from bacteria and viruses using BLASTN [ 13].
As the subsurface anisotropy increased, these effects together with free- and total-oil contaminated areas were further enhanced.
A total of 415 Listeria contaminated samples were further subjected to RAPD (randomly amplified polymorphic DNA) analysis to evaluate the relationship of the contaminants in the final product and those in the environment.
Surgical sites were examined by taking one swab from an area inside the situs and at the moment assumed to be most heavily contaminated, and was further processed following standard microbiological methods.
After isolation of RNA, traces of contaminating DNA were further eliminated by treating RNA samples with RNase-free DNase I (Ambion, Austin, TX) at 37°C for 20 min. Samples were either used immediately or stored at −80°C.
