Our proteins are meticulously prepared to meet the rigorous demands of your research.
Why Choose CrystalsFirst QualityPlus?
The QualityPlus standard from CrystalsFirst guarantees proteins optimized specifically for demanding structural and functional applications, ensuring you spend less time on sample preparation and more time on discovery.
Exceptional Purity
Our proteins undergo stringent, multi-step chromatographic purification, minimizing contaminants that can interfere with crystallization or binding assays. This high purity is crucial for obtaining high-quality crystal diffraction data.
High Homogeneity
Proteins are validated to be structurally and conformationally homogeneous, which is essential for uniform crystal packing and consistent results in a broad variety of biophysical methods (e.g., in NMR, DEL Thermal Shift Assays (TSA) or Surface Plasmon Resonance (SPR)).
Ready-to-Use Concentration
Supplied at concentrations ideal for immediate use in crystallization trials or downstream biophysical campaigns.
Lot-to-Lot Consistency
Rigorous Quality Control (QC) ensures reliable reproducibility across different batches, giving you confidence in long-term projects and publications.
Stop wasting time and resources on unstable, impure protein samples. Invest in CrystalsFirst — QualityPlus and accelerate your path to a successful structure.
