is cDNA concentration 200 ng/ul too high for qRT-PCR-Rea
The gene we are interested in looking at is not very abundant. At 100 ng/ul, the CT value is 30.9 In the literature that I have looked at, people seems to using much lower levels of cDNA. I would actually
Precolumn derivatization of amino acids followed by their resolution by reverse-phase high-performance liquid chromatography (RP-HPLC) is now the preferred method for quantitative amino acid analysis. The derivatization step introduces
