Brief Summary of Small-angle Scattering Assay
Small-angle X-ray scattering (SAXS) is a valuable structure analysis technique applied to acquire data on the shape, structure changes, and size of macromolecules in solution. SAXS is typically used to study the interactions between macromolecules and the functional mechanisms of molecules in cells. This method can offer low-resolution structural graphs of bound proteins, such as an antigen-antibody complex, on the shape, conformation, and binding state.

Workflow of Cell-based Small-angle Scattering Assay Service
The powerful X-ray scattering techniques provided us an insight into the complex interaction between the specific antibody and peptides. A SAS model of the antibody and peptides complex could indicate the shape information on the spatial arrangement of antibodies on an antigen, antibody binding sites, and conformation.

Customer Reviews
-
Streamlined Workflow.
Creative Biolabs' assay facilitated our antibody development by providing critical data on aggregation and conformation from minimal samples, avoiding the need for extensive protein purification. This saved us a lot of time and resources compared to our previous methods. - L***a. -
Unparalleled In-Solution Insight
We were able to confirm our antibody's native-state structure and how it interacts with its antigen using the Creative Biolabs assay. This in-solution data gave us a confidence boost we couldn't get from crystallography alone, helping us choose the best candidates to move forward. - K***n.
FAQs
What is the main advantage of using a B cell-based SAS assay over other structural methods like crystallography?
Our assay provides crucial structural information from samples in their native solution state, without the need for crystallization. This allows us to analyze flexible or unstable molecules that are not suitable for crystallography and to gain insights into their behavior in a more biologically relevant environment.
Can this assay be used for my specific type of antibody or protein?
Absolutely. Our platform is designed to be highly versatile. As long as you can provide the required sample material, our assay can be adapted to characterize a wide range of antibody types, as well as protein-protein and antigen-antibody complexes.
