Periodontal Pockets Microbiota qPCR Analysis at Different Stages of Periodontitis
Poster May 19, 2011
Oksana Zorina and Denis Rebrikov
Six major periodontal pathogens were quantified (with standardization to human gDNA) in periodontal pockets of periodontitis patients and healthy subjects by original qPCR assay. Relative amount of pathogens to total bacterial mass increased for P.gingivalis (100-fold), P.intermedia (10-fold) and T.forsythensis (10-fold).
For circulating cell free DNA (ccfDNA) to be used in cancer research successfully, workflow standardization is essential. Access this poster to discover tips on optimal workflow control, how to yield smaller ccfDNA fragments and the differences in quantification and qualification of ccfDNA.READ MORE
When there is a need to quickly analyze samples using a number of different PCR assays, it is likely that optimal conditions for each assay will not be the same. First, different assays often will require different annealing temperatures for their primers. In addition, amplicons may be designed to be of different lengths and therefore require varying durations of the extension step.READ MORE
