Thomas Fire Update
December 18, 2017 - Dear Customers:
Thank you for reaching out and keeping us in your thoughts while our region deals with the challenges associated with the Thomas Fire. While this wildfire continues to burn through portions of southern California, we thankfully report Wyatt Technology has not been adversely impacted. The air has been smoky but otherwise it’s business as usual. Unfortunately, not everyone in our region was as fortunate and so there’s a way you can help. A “Thomas Fire Fund” has been established by the United Way, American Red Cross and the California Office of Emergency Services to help those in need. Donations can be made through the United Way website at www.unitedwaythomasfirefund.org

Polymer characterization: viscosity is intrinsic
December 15, 2017 - The centrality of multi-angle light scattering to polymer characterization is widely appreciated. SEC-MALS with a DAWN® HELEOS II is the gold standard for determining reliable, accurate distributions of absolute molar mass and rms radius, without having to rely on column calibration, reference molecules that don’t elute like your samples, and assumptions about ideal conformation and column interactions. But once you have mastered SEC-MALS, what’s the next stage? How to obtain even deeper understanding of your macromolecules? And what are your options if SEC-MALS does not work for some of your samples?

Virtual Method Optimization and Size Analysis for FFF
September 11, 2017 - Flow-field flow fractionation (flow-FFF) offers highly versatile separations for the analysis of complex fluids, covering a size range of macromolecules and particles from 1 nm to 10,000 nm. However, flow-FFF is often perceived as a difficult technique to learn because of the multiple parameters available for adjustment.
Our new SCOUT DPS® software simulates flow-FFF from basic physical principles, enabling the virtual optimization of flow-FFF methods and opening up the power of flow-FFF separations to non-experts. SCOUT DPS also analyzes particle size distributions (hydrodynamic radius) by elution time to increase characterization capabilities. This publication in The Column explains how it works.

Protein Quality Control in SPR and BLI High-Throughput Screening Studies
May 9, 2017 - Protein-protein binding studies are only as good as the quality of the reagents used in the experiments. Great resources in terms of instrumentation, sample production and scientist time are typically invested in high-throughput screening of antibodies or fragments to obtain optimal therapeutic candidates, perform epitope binning and rank candidates by affinity and kinetics. However, often little attention is paid to verifying protein solution quality—which can lead researchers down the proverbial rabbit hole, chasing after ephemeral or anomalous results that are caused by degraded proteins. To download a white paper describing a fast, easy and non-perturbing pre-screening method using the DynaPro Plate Reader II, click here.
