Comparison of camel DNA sampled from whole-blood, saliva, and tail-hair

What is it about?

In this study, we examine the differences in the quality and quantity of dromedary camel DNA extracted from each of the following types of commonly used DNA samples: whole-blood, saliva, and tail-hair. We also tested the effects of long-term-storage on the quality and quantity of DNA over a period of nine months. While good quality DNA was extracted from all three sources, we find that the most optimal source of DNA for dromedary camels, especially for the purpose of establishing a biobank, is tail-hair, because it resulted in both an adequate quality and quantity of DNA and relatively low DNA degradation.

Why is it important?

To effectively study camel traits, a biobank of camel DNA specimens with associated biological information is needed. Before establishing such a biobank, we need to know which DNA source is most optimally suited for this purpose, in terms of providing optimal quality and quantity of DNA, and minimal degradation over time.
