preparation of genomic dna from bacteria pdf

Mixtures of different microorganisms representing gram negative bacteria gram positive bacteria and yeasts at different concentrations were extracted with the etna pure extraction protocol including silica column purification and the extracted dna was amplified using pcr reactions specific for the different microorganisms. 10 of 20 µl was loaded on a 1 5 agarose gel using the 1 kb dna ladder as a marker. Dna was extracted from hek293 cells using the purelink genomic dna mini kit.

1 the workflow uses a single 90 min hybridization step and as little as 10 ng input dna. The nextera xt dna library preparation kit enables researchers to prepare sequencing ready libraries for small genomes bacteria archaea and viruses pcr amplicons and plasmids in 90 minutes with only 15 minutes of hands on time. The expected yield of genomic dna isolated from bacteria with the dneasy blood tissue kit or the qiaamp dna mini kit is approximately 10 ug of dna per 2x 10 9 bacterial cells.

Dna concentration was measured using spectrophotometry a 260 and compared.

Preparation of genomic dna from bacteria pdf. Note that yields of genomic dna will vary depending on bacterial strain quality of the starting material growing conditions and the amount of material processed. Both samples were available in three forms.
