Custom Protein Production
Can't find a protein from our catalog to suit your research needs? Our custom protein production service can help.
Whether you're starting from scratch or customizing an existing protein from our catalog, our team of scientists will work with you to deliver a protein tailored to your goals. We specialize in custom protein development, including unique variants and mutants, specific sizes and formulations, non-standard labels, and more.
Protein Expression and Purification
We provide flexible, end-to-end support for recombinant protein expression and purification, allowing you to start your project exactly where you need. We offer expression services in a range of systems—including E. coli, Bacillus subtilis, Saccharomyces cerevisiae, and Pichia pastoris—with proven success in producing kinases, cytokines, antibodies, and other complex proteins. Whether you need standalone expression or full-service purification, our experienced scientists are here to deliver reliable, high-yield results.
Gene Cloning
Our user-friendly Gene Cloning service is designed to streamline your protein expression workflow. Our proprietary expression vectors are optimized for high-level expression and can incorporate fusion tags to enable rapid purification and easy assay detection. For applications requiring native protein, tags can be cleanly removed using specific proteases.
Our gene cloning process includes PCR amplification of your gene of interest—from sources like cDNA libraries, genomic DNA, cell lines, hybridomas, or BAC clones—followed by cloning into a vector and sub-cloning into our expression system. Every cloned gene is fully sequenced in both directions to confirm accuracy and correct reading frame, ensuring reliable results from the start.
