What’s the difference between the 4-10 Kb vs2 and 6-10 Kb vs3 high pass protocols?

Customers may have noticed two very similar cassette definitions; 0.75%DF Marker S1 high-pass 4-10kb vs2 and 0.75%DF Marker S1 High-Pass 6-10kb vs3. Since these two protocols cover a similar range, they might seem a bit redundant. However, both of these … more »
