BlogUnderstanding why GPCRs are difficult to study
In this blog post we delve into the reasons behind why elucidating GPCR structures are so important as well as why they are hard to study.
BlogProtein analysis techniques - a history and timeline
Proteins were discovered in the late 18th century, but analytical methods to observe them were not developed until more than 100 years later. This timeline shows when different techniques were developed.
BlogProtein aggregation - why it matters, and how to study it
A growing field of research is dedicated to protein aggregation, which can be useful, functional or unwanted. This article explores some of the reasons why proteins aggregate, and details the techniques available to study it.
BlogHow does Microfluidic Diffusional Sizing (MDS) compare to Dynamic Light Scattering (DLS) for protein size tests?
Measuring the size of proteins provides insights into folding and conformations, aggregation and oligomerization. We compare and contrast the benefits and limitations of two popular techniques - DLS Dynamic Light Scattering, and MDS Microfluidic Diffusional Sizing.
BlogHow does the Fluidity One compare to UV-Vis spectrophotometers in testing the concentration of proteins?
UV-vis absorbance testing is a popular method for rapid testing of protein concentration with only a small sample volume needed. Here we compare this method to Microfluidic Diffusional Sizing (MDS), as used on the Fluidity One, to see how the workflow, accuracy, test method, range and limitations compare.
BlogProtein size - how do I measure it, and why is it important?
An overview of why protein size matters, and what structural and functional information protein size can reveal. To understand proteins and their function, we have to understand the way they fold, aggregate and interact. Conformation is key to protein function and can be revealed by measuring size.
Different methods for measuring protein size are summarised, and comparison is made, considering the method, range, cost and limitations of each technology.
BlogWhat analytical laboratory methods are available for protein quantification? How do they compare?
Quantification is an essential part of protein analysis and quality control. Here we look at the various approaches for protein quantification, their advantages, and their limitations.
