How does it work?
Getting started is simple - just share your protein or peptide sequence and project requirements with our team. From design and optimization to synthesis, purification, and quality control, we handle every step with precision. You'll receive expert support and regular updates, ensuring your custom peptide or protein is delivered to your exact specifications and ready for research.
We begin by reviewing your peptide or protein sequence and project goals to assess technical feasibility.
Our team optimizes the gene or peptide design for expression, solubility, and stability - tailoring codons, tags, and constructs to maximize yield and functionality.
Using the chosen system we produce and purify your protein or peptide to the highest standards.
Final products undergo rigorous quality control and validation, ensuring they meet your specifications.
