A) function as a filter and a barrier to cell or pathogen movement. B) attach epithelial cells to the underlying tissue. C) are secreted partially by epithelial cells and partially by the cells of the underlying tissue. D) All of the choices are correct. D) All of the choices are correct.
The table represents the results of an experiment where the effects of pH buffers on an enzyme found in saliva (amylase) were studied. A spectrophotometer set at 500 nm was used to measure absorbance at the various pH levels every 20 seconds for 2 minutes. The higher absorbance values would indicate greater enzyme activity.

Easy and accurate salivary DNA analysis enables the genotyping of well-characterized single nucleotide polymorphisms (SNPs) that can profound ly impact your research. Research has revealed that salivary DNA is equivalent in quantity and purity to DNA obtained from blood (1-3), and that the stability of salivary DNA is good when proper methods of handling are employed (2,4). With Salimetrics’ DNA extraction protocol and greater than 99% call rate or genotype assignment, you can expand your data set to draw better conclusions by simply adding DNA analysis to your study design. Salimetrics DNA Analysis Service can test for over 160,000 polymorphisms. Feel free to Contact Us to discuss your project and set-up a custom panel to fit your research focus and budget.

Ask participants to follow these steps: Wait at least one hour after eating a meal before collecting saliva. Rinse mouth thoroughly with water to remove any food particles or other contaminants, then wait a full ten minutes before collecting the saliva sample.
DNA in Saliva. The DNA in saliva originates from cells that are shed from the inner linings of the mouth and from white blood cells. These DNA-containing cells are collected, and the DNA is then extracted by various methods.
