Looking on the datasheet, it states that there is 250 ug of DNA per vial and that the vial has 100 x 5uL loads (500 uL volume). DNA concentration is 0.5 ug/uL. Loading 5 uL per well therefore provides a DNA load of 2.5 ug per well.

General description
Sigma′s DirectLoad™ 1 kb Ladder contains 11 fragments consisting of 500 bp repeats from 0.5 to 3 kb, 1 kb repeats from 3 to 6 kb, and 2 kb repeats from 6 to 10 kb. For NA electrophoresis, 5 ul of the marker can be loaded directly into a single lane on an agarose or polyacrylamide gel. Suitable for use in Northern and Southern blotting.
Application
Suitable for size determination of dsDNA by DNA electrophoresis with either agarose or polyacrylamide gels.
Features and Benefits
- Ready-to-load
- Easy-to-use
- Popular band sizes
Other Notes
Contains 11 fragments consisting of 500 bp repeats from 0.5 to 3 kb, 1 kb repeats from 3 to 6 kb and 2 kb repeats from 6 to 10 kb.
For optimal resolution, the recommended agarose gel concentration is 0.75%.
Sigma′s DirectLoad™ 1kb Ladder is provided in a gel-loading solution of 2.5% Ficoll (Type 400), 0.0125% bromophenol blue, and 0.00625% xylene cyanol.

Aron M Geurts et al.
Methods in molecular biology (Clifton, N.J.), 597, 211-225 (2009-12-17)
The genetic dissection of physiological and pathological traits in laboratory model organisms is accelerated by the ability to engineer loss-of-function mutations at investigator-specified loci. This chapter describes the use of zinc-finger nucleases (ZFNs) for the targeted disruption of endogenous rat
Articles
Choose the appropriate markers and ladders for nucleic acid size determination of samples separated by electrophoresis. Determine size of DNA, RNA and PCR-generated fragments using agarose or polyacrylamide gels.
Markers for gel electrophoresis aid size determination of DNA, PCR fragments, and RNA, staining well with common nucleic acid stains.
Protocols
JumpStart™ Taq DNA Polymerase is an antibody-inactivated, hot start enzyme.
Protocol using antibody mediated hot start polymerase. Method has short activation period (<1min), and results in higher yields and more specificity over standard PCR methods.
Protocol for high fidelity amplification of long PCR fragments up to 22kb from complex DNA mixtures and up to 40kb from simple DNA mixtures.
