A different DNA ladder from NEB (Cat #N3200L) comes as 500 uL of a 1000 ug/mL solution and is not pre-mixed with the 6 X DNA loa
JulijaS [17]

Answer:

4 ul Loading Buffer + 19.70 ul dH2O + 0.30 ul DNA Ladder

Load 12 ul on the gel.

Explanation:

DNA Ladder concentration = 1000 ug/ml

1000 ug DNA in 1 ml DNA Ladder solution →    150 ng DNA = 0.15 ug DNA in..... 0.00015 ml = 0.15 ul DNA Ladder solution

6x DNA Loading Buffer → it has to be diluted by an equal volume 6 times (1 ul LB + 1 ul distilled H2O)

An appropriate volume to load on an average agarose gel is 12 ul, so:

2 ul Loading Buffer + 9.85 ul dH2O + 0.15 ul DNA Ladder = 12 ul

But since 0.15 ul is a very small volume and mistakes could be made while measuring it, let's make double:

4 ul Loading Buffer + 19.70 ul dH2O + 0.30 ul DNA Ladder = 24 ul

And load half of that solution (12 ul) on the gel.
