Concentration of DNA?

10 February 2021 1 7K Report

Hello everyone! Is a normal value 295.8 ug/ul for cDNA? If not what does it mean? Where is the mistake? The measurement was done with nano drop. Thank you!

Asif Ali

ScanDrop & NanoDrop are most common.

260/230/280 ratio show DNA, salt and protein concentration

For details of protocol.
