Design Your Project

Your target / construct

Calixar offers multiple cleavable tags (His, Flag, Strep, Avi…) and/or protein-fusion (GFP, RFP…), and will assist you to select optimal options for your project.

Your production process

Calixar’s purification process includes solubilization and stabilization screening in various proprietary and commercial detergents and/or SMALPs. 1- or 2-step affinity purification followed by a size-exclusion chromatography ensures >90% purity degree.

Calixar’s quality control process includes:
Purity evaluation
✓ Protein quantification
Homogeneity determination
Cryo-stability assay

In addition, Calixar can develop specific protein characterizations such as:
Thermal shift assay
Functional assay (enzymatic activity, proteoliposome ion flux assay
Ligand binding assay (radiobinding, fluorescence polarization, microscale thermophoresis

From µg- to mg-scale production, Calixar will fit all your needs of proteins for your R&D developments.
Based on your final application, Calixar is able to deliver your purified target in various formats such as micelles of detergent, SMALPs, amphipols, nanodiscs and proteoliposomes.
