Can transcriptional elongation factor 1 alpha (tef) be used as a phylogenetic marker for protists and metazoa?

Hello, I know tef can be used as a phylogenetic marker for fungi. But what about other organisms? For eukaryotes, 18S rRNA is definitely too conservative in many cases. By the way, COI is used in...

Is RNA-seq reads number related to the quality of RNA preparation?

Dear all, I don't have much experience of RNA-seq. I noticed that the reads number of one treatment (3 individuals) was lower than the other treatment. Similarly, the signal intensity of samples...

Dear Fang,

I think you may find the answer by searching in context of stable isotopes. Maybe this paper will be helpful (unfortunately I have no access to it:

You are what you eat (plus a few ‰): The carbon isotope cycle in food chains

by: M. J. Deniro, S. Epstein

Geological Society of America Abstracts with Programs, Vol. 8 (1976), pp. 834-835

If not this one, check who is citing it.
