FAQ: Does the library quant require a size correction when using the NEBNext® Library Quant Kit for Ultima Genomics® (NEB #E3410)?

Yes. The intercalating dye used in the NEBNext Library Quant Kit for Ultima Genomics binds DNA in proportion to the number of base pairs per double-stranded DNA product, so it is necessary to correct for product length by normalizing to the size of the DNA standard, 200 bp. All quants are simply multiplied by a correction factor, 200/library size. This is done automatically using our online tool for NGS Library Quant.
