The NDF experiment detects all six protein spikes, ranging from 12 kDa to 470 kDa at 1 ppm, with no bias towards smaller <t>HCPs,</t> allowing for an unbiased analysis. In contrast, ND only detects the Mb and Cyt c spikes, which are below 20 kDa, losing detection <t>for</t> <t>proteins</t> larger than 50 kDa. At a 0.5 ppm spike level, NDF can still detect all spikes except the largest 470 kDa FN and provides nearly twice the unique peptide identification for Mb and Cyt c compared to ND, demonstrating a lower detection limit and offering greater identification confidence in the NDF method.
