Our website has a fresh new "look"
We've updated our site with modern design and easier navigation, but you'll still find the same quality Dharmacon™ reagents and Mimix™ reference standards that you love.
What is the difference between ctDNA and cfDNA?
ctDNA is circulating tumor DNA: fragmented DNA in body fluids (e.g. blood plasma) which has come from cancer cells. cfDNA is cell-free DNA, which describes the fragmented DNA in the body fluids originating from any cell type, which can include both normal and cancer cells.
Please note that our cfDNA and ctDNA reference standards are made in the same way. Newer reference standards have been named "ctDNA" to better reflect the applications they are used for.
