Carna's Biotinylated Proteins
For binding studies such as Surface Plasmon Resonance (SPR) assays, proteins often need to be immobilized onto sensor chip surfaces while maintaining their native conformation and high biological activity. For these applications, we recommend Carna Biosciences' site-specifically biotinylated proteins, which are designed with a single biotin molecule introduced in a controlled manner to enable efficient immobilization while preserving protein integrity.

In addition to our standard product portfolio, Carna Biosciences also offers the development of custom kinase mutants and tailor-made kinase proteins to meet specific research requirements.

If the protein you are looking for is not listed in our catalog, please feel free to contact us for further assistance.

Carna Biosciences will close our operation from April 29 (Wed) through May 6 (Wed), 2026 for National holidays in Japan. Our normal business will be resumed on May 7, 2026, and all the messages received and orders placed within the holiday period will be dealt with and/or answered back right after that.
Our subsidiary in the U.S.A.and all our distributors outside of Japan will remain open business as usual.
We regret any inconveniences this might cause to our valued customers.

Five pseudokinases have been newly released！
Pseudokinases are proteins that structurally resemble kinases but lack the amino acid residues essential for catalytic phosphorylation activity, rendering them enzymatically inactive. They account for approximately 10% of the entire human kinome.
Their implication in a broad spectrum of diseases underscores their potential as therapeutic targets, paving the way for innovative treatment strategies that circumvent traditional reliance on enzymatic activity.
Carna's pseudokinases are available as biotinylated proteins for versatile applications across a wide range of research and development needs.
