Q&A – OMNISEC for Protein Characterization – Demo at your desk

Recently, I’ve presented a new webinar focusing on the protein characterization using the OMNISEC, the highest quality Gel Permeation Chromatography (GPC) / Size Exclusion Chromatography (SEC) system for the measurement of absolute molecular weight, molecular size, intrinsic viscosity, branching and other parameters. Thank you to all participants for your interest and attention during the webinar.
In this webinar, I highlighted the key features and benefits of the OMNISEC system. How to run samples and analyze data and how to access repeatability of multiple sample measurements.

As usual, after the live section of …

MicroCal DSC – Creating confidence in your protein stability data

My introduction to Differential Scanning Calorimetry (DSC) was a postdoctoral fellow in the late 1980s.  I was producing mutant forms of the enzyme thymidylate synthase, and I needed to characterize the effects amino acid changes had on the overall stability of the protein.  Using a DSC instrument at our facility, I compared the thermal stability of the different mutants to wild-type protein by ranking the thermal transition temperature (TM). As I recall, I needed about 2 mg -4 mg protein per DSC experiment, which was a lot of protein at …

OMNISEC Contest Winners

Last year we asked you to tell us about your most interesting or challenging Gel Permeation Chromatography (GPC) / Size Exclusion Chromatography (SEC) sample and why it presented such a challenge. For instance, if you’ve made two polymers which should be different but you can’t tell apart; or have polymers that are so small you don’t have the sensitivity to measure accurately.
The top 3 submissions that presented the biggest challenge to our new OMNISEC advanced GPC/SEC system would be awarded with a full sample analysis along with a prize of …
