DNA ladders are supplied in a loading buffer that is ready to use on agarose and polyacrylamide DNA gels. The ladders are suitable with TBE, TAE, SB and LB electrophoresis systems.

These DNA markers are used to determine size of unknown DNA fragments. If using within 2–3 days, they do not need to be refrigerated and can be stored right on a shelf. If storing for longer time periods, freezing is recommended.

Ship date is required.

RiboReady™ Color Micro RNA Ladder is made for precise sizing of RNA molecules in denaturing acrylamide gels

8 fragments ranging from 50 to 2000 bp for easy band identification

10 fragments ranging from 50 to 500 bp for easy band identification

Rainbow™ molecular weight markers enable faster and simpler identification of proteins on SDS polyacrylamide gels. These ready to load markers provide sharper, more intense bands on gels and blots, and have improved band spacing for more accurate molecular weight determination. The bright, distinctive colours of the markers allow easier confirmation of transfer to blotting membranes and orientation.

This mixture contains seven purified proteins that range in size from 14 to 120kDa

25/100bp mixed DNA ladder is specially designed for determining the size of double strand DNA from 25–2000 base pairs

Lambda DNA fragments prepared by the digestion of purified lambda DNA with the restriction endonuclease Hind III

Amersham™ ECL™ Plex™ fluorescent Rainbow™ markers are protein molecular weight markers optimised for use with the ECL™ Plex™ Western blotting detection system. They are designed to provide visible marker bands on gels and membranes, as well as fluorescent images using Cy3 and Cy5 channels.

Mouse Anti-Blue Molecular Weight Ladder Peroxidase Conjugated Antibody

Prestained Protein Ladder ab234617 is a blue protein standard with 11 pre-stained proteins covering a range of MW from 10-180 kDa. ab234617 is designed for monitoring protein seperation in SDS-polyacrylamide gel electrophoresis and verifying Western transfer efficiency on membranes (PVDF, nylon, or nitrocellulose) and for approximating the size of proteins.

Small RNA Diluent Marker, 4 mL. 1 nt lower marker. For use with the Fragment Analyzer systems and the DNF-470 kit.

Markers, 1bp + 6000bp, 3.2mL. 1 bp lower marker; 6,000 bp upper marker. For use with the Fragment Analyzer systems and the DNF-910CP kit.

pI markers are lyophilized mixtures of stable, salt-free, highly purified proteins.

Prestained Protein Ladder AB313996 is a combination of 11 pre-stained proteins with molecular weights from 3 to 260 kDa. This prestained protein ladder keeps track of the size and separation of proteins during SDS-polyacrylamide gel electrophoresis, approximating the target protein size and validating the Western transfer efficiency on PVDF, nylon, or nitrocellulose membranes.

Amersham™ ECL™ DualVue™ Western blotting markers perform two key functions. Firstly, the prestained marker proteins confirm protein transfer in addition to clearly defining blot orientation. Secondly, the recombinant tagged proteins are detected on film or by CCD imaging in conjunction with the target protein(s) of interest, enabling highly accurate molecular mass determination of the target protein(s). The tagged markers are detected easily and specifically by means of a specific conjugate that eliminates any cross contamination between target protein(s) and markers.
