Protein Engineering and Analysis
Over the years, scientists from Creative Biostructure have been actively working on the characterization of proteins using a variety of techniques, as well as the engineering of proteins for various applications. The extensive experiences gained in these areas enable us to provide customized services in a timely and cost-effective manner.
Protein Engineering
Protein engineering is the process of modifying the structures of proteins and assigns them new and/or desirable properties in terms of activity, solubility, affinity, stability, specificity, resistance, etc. The most commonly applied approaches for protein engineering include de novo design, rational design, and directed evolution. Creative Biostructure offers protein evolution and engineering services covering the full cycle of protein engineering to satisfy customers’ requirements.
Protein evolution can be described as the changes over time in protein shape, composition, and structure. This process is closely related to the changes and selection of DNA polymorphisms and mutations due to protein sequence change responding to alteration in DNA sequence. Creative Biostructure adopts sensitive sequence profile methods and structure comparison methods to determine evolutionary relationships not detectable at the DNA-level.

Protein Analysis
With the rapid growth of genomic sequencing data, an increasing number of proteins have emerged with great research interest. To further understand their biological roles and pave the way for structure-function relationship studies, many efforts have been made toward the development of various methods that have been proved effective in the biophysical characterization of biomolecules. Creative Biostructure provides a variety of sensitive techniques and appropriate strategies for protein analysis. The methods include but are not limited to epitope mapping, protein interaction analysis, and protein thermodynamics analysis.
