Using Bio-Rad’s PDQuest Software to Generate a Match Rate between 2-D Electrophoresis and Western Blotting
2-D electrophoresis followed by immunodetection of protein spots using western blotting is adopted commonly in proteomics studies. Here we present step-by-step instructions for obtaining accurate overlaps between the gel and the blot using the PDQuest 2-D gel analysis software.
A Novel Biotinylated Ligand-Capture Method with Surface Regeneration Capability for Label-Free Biomolecular Interaction Analysis
Ligand-capture approaches using biotin as an affinity tag are often utilized in biomolecular interaction analyses with surface plasmon resonance (SPR) biosensors. However, a drawback to using biotin is that it makes surface regeneration of SPR sensor chips difficult. Here is a strategy that facilitates surface regeneration when using biotinylated ligand-capture approaches to SPR analysis.
Analyzing Binding Kinetics with Surface Plasmon Resonance Complemented with Direct Mass Spectrometry on the Same Sensor Chip
Surface Plasmon Resonance (SPR) is an optical phenomenon that is used for the label-free analysis of the binding of any two molecules in real-time.

Video Tutorial for Analyzing Binding Interactions with Histidine-Tagged Proteins
Analyzing antibody binding to histidine-tagged proteins is not always easy because of inherent problems such as nonspecific binding and loss of analyte response associated with these tagged proteins. Optimization of these factors is key to precisely measuring the binding kinetics of these proteins.
Transitioning from Chemiluminescent to Multiplex Fluorescent Blotting: Things to Consider
Today many researchers are considering changing their western blot detection method from chemiluminescence to multiplex fluorescence. There are several drivers behind this trend. Most significantly, fluorescent detection allows users to multiplex their western blots, enabling simultaneous detection of several target proteins at once, reducing or eliminating the need to strip and re-probe. Other benefits of fluorescence include better dynamic range, more quantitative results, and better signal stability over time.

Guidelines for Developing Robust and Reproducible High-Resolution Melt Analysis Assays
Classifying and understanding genetic variation between populations and individuals is an important aim in the field of genomics. High resolution melt (HRM) analysis is the quantitative analysis of the melt curve of a DNA fragment following amplification by PCR and can be considered the next-generation application of amplicon melting analysis. Careful sample preparation and planning of experimental and assay design are crucial for robust and reproducible results.
Using the Precision Plus Protein™ WesternC™ Standard as a QC Tool at Key Steps in Your Electrophoresis and Blotting Workflow
As a fundamental tool in protein research, it is critical that all steps of the electrophoresis workflow (from running gels to visualizing blots) are performed successfully to ensure accurate, reliable, and reproducible results. Protein standards are often used to monitor electrophoretic separation and transfer efficiency but do not always enable ladder visualization after blot development.
