Example sentences for: spanned

How can you use “spanned” in a sentence? Here are some example sentences to help you improve your vocabulary:

  • cDNA prepared from 0.5 μg RNA was subjected to PCR using murine gene-specific primers for 8 different cytokines and chemokines (Table 1) as previously detailed [ 18 ] . All of the primer pairs spanned at least one intron in the corresponding genomic DNA.

  • With an estimated gap size, LBNL used one of five gap-filling methods to determine their sequence: first, gaps less than 500 bp were sequenced using custom primers designed by consed and a 3-kb or 10-kb plasmid as DNA template; second, gaps between 500 bp and 2.5 kb that were spanned by a 3-kb clone were completed by sequencing the 3-kb clone using a transposon-based sequencing strategy, described below; third, gaps between 2.5 kb and 10 kb that were spanned by a 10-kb clone were completed by sequencing the 10-kb clone using a transposon-mediated sequencing strategy; fourth, gaps larger than 10 kb were completed by sequentially sequencing multiple 10-kb clones to walk across the gap.

  • The remaining datasets were considered in the following order and resulted in an additional one or two points: the cDNA and annotation data were analyzed to determine if any entry in this class spanned the entire length of the CDS; if so, an additional two points were assigned, and if not, GenBank/EMBL/DDBJ and error report entries were analyzed and if any spanned the length of CDS, two points were assigned; if none of these data classes corresponded to the full-length CDS, then the existence of partial cDNA data and/or overlapping EST data merited one point.

  • Our assay investigated tissues that spanned most of this period (see Methods), including four time points in the critical period surrounding P10 to P18 (P10, P12, P14 and P18).

  • To further investigate this possibility, we performed RT-PCR to generate cDNAs that spanned exon 20 of EGFR and included sequences from exon 19 and 21.
