KACTUS will be at the Antibody Engineering & Therapeutics conference in San Diego December 4-8th.
Chat with us in person at booth #103 to learn more about our Virus-Like Particles, MHC Complexes, CD3 Proteins and more!
We currently offer 2000+ recombinant proteins for you to choose from. But don't hestitate to reach out to us if you need customization of one of our catalog products or let us know if you're looking for a protein not listed and we can work with you to set up an expression system.
Custom Production
Don't see what you're looking for? We offer customization of signal peptide, codon, tag, etc. for any of our catalog products or let us know if the protein you are looking for is not listed and we can work with you to set up an expression system for it.

Virus-Like Particle (VLP) Displayed Antigens
VLP displayed antigens do not contain infectious genes and display multiple copies of antigen per VLP to enhance immunogenicity. They effectively activate humor and cellular immune responses.
| Human CD24 | Human CCR2b |
| Human Biotinylated Claudin 18.2 | Biotinylated Human GPRC5D |
| Cynomolgus Claudin 6 | Human Claudin 6 |
| Cynomolgus CD24 | |
| Human GPC3 | Human TM4SF1 |
| Mouse GPRC5D |
MHC-I Complexes
We offer various types of MHC-I Complexes including HLA-A, HLA-G, and HLA-E. Our product line includes tetramer complexes and biotinylated versions. Our MHC-I complexes are mammalian-derived and have low endotoxin levels for cell-based assays. We also offer LILRB/LILRAs, receptors for HLA-G.
CD3 Proteins
CD3 is expressed on the surface of T-cells. Using our SAMS™ technology platform, we have developed monomer, homodimer, and heterodimer versions of CD3 protein in various species and tags. They are ideal for immunization, antibody screening, or affinity determination (ELISA, SPR, etc).
