Recombinant Proteins

Recombinant Proteins
LSBio offers an extensive selection of high-quality recombinant proteins of human, murine, and rat origin, produced in a variety of expression systems that include bacteria, yeast, baculovirus infected insect cells, and mammalian cells. Protein categories include Growth Factors, Cytokines, Chemokines, Neurotrophins, Proteases, and other miscellaneous proteins, all of which are rigorously tested to meet the research and development demand for excellent quality and uncompromising biological activity. Our recombinant proteins can be used for a variety of applications, including functional assays, high throughput screens, antigen generation, structural analysis, cell growth and differentiation, cell signaling, and studies involving disease onset and progression.
