Example sentences for: pyub

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

  • In the λ phage library, ~225 cosmids represent one genome-equivalent of M. tuberculosis [ 20 ] . An E. coli (pYUB178::H37Rv) library was created by infecting E. coli XL1-Blue with the λ phage library.

  • The blots were hybridized to pYUB178 plasmid DNA labeled using the ECL Direct Nucleic Acid Labeling and Detection System (Amersham).

  • The pYUB178 plasmid and the λ phage library of pYUB178::H37Rv cosmids were generously provided by Dr. William Jacobs, Albert Einstein University, New York, NY [ 20 ] . The cosmid library contains 30-50 kb fragments of M. tuberculosis genomic DNA generated by partial Sau 3A digestion cloned into Bcl I-digested pYUB178.

  • A cosmid corresponding to the one in the sur3 clone was isolated from the E. coli (pYUB178::H37Rv) library by probing colony blots with the 4.5 kb Bam HI/ Eco Rl fragment of the M. tuberculosis genomic DNA insert in the plasmid recovered from the sur3 clone.

  • In experiments in which THP-1 cells were infected at a MOI of 50:1 (results in ~1 phagocytosed M. smegmatis bacterium per macrophage) with a mixture containing equal numbers of bacteria of the xylE -expressing control strain and a strain carrying the cosmid vector pYUB178, the ratio of recovered white colonies to yellow colonies was 1:1 at all time points (data not shown).
