Recombinant Proteins
At Chemsis, we provide recombinant proteins engineered for precision and consistency.
Recombinant Proteins
Recombinant proteins are laboratory research reagents produced through genetic engineering by inserting a specific gene of interest into a host organism and its subsequent expression.
Our portfolio includes cytokines and growth factors, proteins for studying immuno-oncology targets, enzymes, Animal-Free and GMP-grade proteins, custom protein development services, and more.
At Chemsis, we strive to provide products with only the highest quality. Protein identity, purity and biological activity are assured by our robust quality control and assurance procedures.
Explore Recombinant Proteins by Intended Use
Recombinant proteins used in gene therapy are engineered proteins used to replace, inhibit, or enhance the function of genes to treat or prevent diseases.
