Need to make challenging light scattering measurements?

You may have heard it before - but not all instruments for measuring light scattering are equally capable. Field proven in hundreds of labs around the world the Bl-200SM goniometer system is a precision instrument designed to undertake the most challenging dynamic light scattering and static light scattering measurements. As you would expect from a powerful research grade system the BI-200SM can measure light scattering over a wide angular range (8° to 155°) and offers fine adjustment of measurement angles to 0.01° making centre of rotation measurement easier when aligning cells. Precise repeatable data is ensured by automated heating and cooling of the sample cell using an external recirculating system.

Studying Antibodies with Dynamic Light Scattering

Studying Antibodies with Dynamic Light Scattering

One of the fastest growing classes of pharmaceutically active biologics are antibodies. These highly versatile #proteins are increasingly used in immunoassays, in vaccine production, and as the primary component of a wide array of injectable protein drugs. In all these applications it is essential that antibodies remain intact, and monomeric. Failing to adhere to these strict and exacting standards compromises the processability, activity, and shelf stability of antibody-based products. Dynamic light scattering (DLS) is a powerful technique that can be used to detect aggregation of proteins and determine the size of monomeric protein with a very high degree of certainty.
