Description
100 bp-DNA-Ladder extended is a lyophilised DNA size standard supplied together with gel loading buffer for electrophoresis applications. The ladder is not pre-dyed, allowing users to apply the stain or dye system that best suits their imaging setup. Density is specified as 1 g/cm³. The extended 100 bp format is intended to cover a broader fragment range than a basic 100 bp set, supporting sizing of PCR products and other double-stranded DNA species on agarose or polyacrylamide gels, including vertical PAGE used for biomolecule separation. Reconstitute the lyophilisate, mix with the included loading buffer, and run under standard conditions for your gel percentage and buffer system. This extended ladder provides a clear reference track without pre-added dye, giving flexibility in post-electrophoresis visualisation while maintaining a familiar 100 bp step pattern for fragment assignment.
This article is part of Protein extraction, purification & markers, in Protein biology & Western blot.

Questions about 100 bp-DNA-Ladder extended, DNA-ladder (lyophil.) + gel loading, 50 µg, plastic
What is this article?
100 bp-DNA-Ladder extended, DNA-ladder (lyophil.) + gel loading, 50 µg, plastic is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Protein extraction, purification & markers, inside Protein biology & Western blot, in Microbiologie.
Extraction reagents break the cell and keep the protein soluble. Purification resins and columns, often an affinity tag such as His, pull one protein out. A marker is a set of known masses run in the next lane. The mass range of the marker has to cover the protein being sought.
Protein work separates a mixture, then asks which protein is which. Extraction and purification take the protein out of the cell. A marker shows the masses. A Western blot moves the separated proteins onto a membrane and probes them with an antibody. The membrane, nitrocellulose or PVDF, has to bind the protein and survive the washes. Antibodies and methods are in PubMed. Reference material is at ATCC.
