With fluorescence correlation spectroscopy, one protein is labeled with a fluorescent dye and the other is left unlabeled. The two proteins are then mixed and the data outputs the fraction of the labeled protein that is unbound and bound to the other protein, allowing you to get a measure of K D and binding affinity. You can also take time ...
Protein detection can monitor soybean protein labeling system in processed foods to protect consumers in a reliable way. [8] The labeling for soybean protein declaimed by protein detection has indicated to be the most important solution. [8] Detailed labeling description for the soybean ingredients in refined foods is required to protect the ...
A typical workflow of a peptide mass fingerprinting experiment. Peptide mass fingerprinting (PMF), also known as protein fingerprinting, is an analytical technique for protein identification in which the unknown protein of interest is first cleaved into smaller peptides, whose absolute masses can be accurately measured with a mass spectrometer such as MALDI-TOF or ESI-TOF.

Specialist using "QIAsymphony", an automation platform for molecular diagnostic tests. Molecular diagnostics is a collection of techniques used to analyze biological markers in the genome and proteome, and how their cells express their genes as proteins, applying molecular biology to medical testing.
Quantitative proteomics has the largest applications in the protein target identification, protein target validation, and toxicity profiling of drug discovery. [24] Drug discovery has been used to investigate protein-protein interaction and, more recently, drug-small molecule interactions, a field of study called chemoproteomics. Thus, it has ...
Robotic preparation of MALDI mass spectrometry samples on a sample carrier. Proteomics is the large-scale study of proteins. [1] [2] Proteins are vital macromolecules of all living organisms, with many functions such as the formation of structural fibers of muscle tissue, enzymatic digestion of food, or synthesis and replication of DNA.
Western blot workflow. The western blot (sometimes called the protein immunoblot), or western blotting, is a widely used analytical technique in molecular biology and immunogenetics to detect specific proteins in a sample of tissue homogenate or extract. [1]
Protein–protein interaction screening refers to the identification of Protein–protein interaction with high-throughput screening methods such as computer- and/or robot-assisted plate reading, flow cytometry analyzing. The interactions between proteins are central to virtually every process in a living cell.
