Ladders and Markers Products & Reviews

The WesternSure Protein Ladder is the only pre-stained, multi-colored protein ladder that provides chemiluminescent signal for film and digital detection. It will fit with your current protocol without optimization and does not rely on strep-tagged HRP or secondary antibody binding. The WesternSure protein ladder works with a variety of substrates and provides a vibrant color scheme that allows you to quickly orient your membr…

Chameleon Vue Pre-stained Protein Ladder offers multi-colored, pre-stained proteins for molecular weight estimation

Chameleon Duo Pre-stained Protein Ladder provides multi-colored, pre-stained bands for visual inspection and two-color near-infrared detection. It includes 11 protein bands from 8 to 260 kDa.

OxyBlot™ Protein Standard is composed of five proteins (phosphorylase B, BSA, ovalbumin, carbonic anhydrase, trypsin inhibitor) containing 1-3 dinitrophenylhydrazone (DNP) residues per protein. These attached DNP moieties permit the visualization of the proteins by the detection system of the OxyBlot™ Protein Oxidation Detection Kit. OxyBlot™ Protein Standard serves as an internal control for the electrophoresis, western trans…

CpGenome™ Universal Methylated DNA is enzymatically methylated human male genomic DNA. This product is intended for use with the CpGenome™ DNA Modification Kit (S7820) or with amplification primers. It can be used as a methylation-positive control for gene methylation studies.

Perform high sensitivity protein electrophoresis with the 2100 Bioanalyzer System. The High Sensitivity Protein 250 assay provides a broad dynamic range with sensitivity down to Silver Stain comparable levels. Efficiency is enhanced by eliminating handling of SDS-PAGE slab gels, staining or, imaging steps.

The Supercoiled DNA Ladder contains fragments from 2 kb to 10 kb at 1-kb increments and an additional band at 12 kb. Each supercoiled band is at a known concentration, with the 7-kb band at a higher concentration than the others. The resulting brighter band in the middle of the ladder acts as a useful reference point.  Accurate size determination facilitated by evenly spaced bands  Fragments are exact multiples of 1000 bp…

Novel protein markers for visible tracking & accurate sizing on any Western blotTrail Mix™ Western Markers consist of the Perfect Protein™ Western Markers supplemented with a group of three prestained indicator proteins to allow direct visualization of protein mobility during electrophoresis. Trail Mix Western Markers and Western Blot Kits have all of the features of Perfect Protein Western Markers and Western Blot Kits, plus…

The MagicMark XP Western Protein Standard is specifically designed for easy and convenient protein molecular weight estimation directly on Western blots.
