BioCrestSci is a recombinant protein supplier offering 16,000+ recombinant proteins for research. All catalog products in this collection are in stock and ready to ship, helping laboratories source commonly used targets without waiting for a new production run. The portfolio supports immunology, cell biology, oncology, infectious disease, neuroscience, diagnostics research, assay development and drug discovery.
Researchers can explore proteins from human, mouse, rat, non-human primate, microbial, viral and other species. Available expression systems include E. coli, mammalian cells, insect cells and yeast, with system and construct details provided on individual product pages. The catalog also includes untagged and tagged formats such as His-tagged, Fc-tagged, Avi-tagged and biotinylated proteins. These options support workflows including ELISA, western blotting, SPR/BLI, immunization, protein-interaction studies, cell-based assays, screening and structural research.
