System Biosciences (SBI)

Accelerate your research in exosomes, cell, and molecular biology

BioCat's long-standing premium partner System Biosciences is a biotech company that has delivered innovative products and services for molecular and cell biology research since January 2004, when SBI introduced their first lentivectors and pPACK lentivirus packaging systems. BioCat has been granted exclusive distribution rights for Germany since September 2025.

They focus on being the first to bring the newest methodologies to market - SBI was the first company to deliver exosome research reagents - so researchers can quickly take advantage of the latest, most powerful approaches.

Dedicated to quality, many of SBI's products and most of their service offerings are completed in their state-of-the-art facility in Palo Alto CA. This enables them to maintain control over manufacturing conditions and quality and ensures that service projects remain confidential and project status updates are delivered frequently and in a timely manner.

Exosome Research Tools

Get everything you need for studying and using exosomes, from isolation and characterization, to cargo profiling and engineering, and more. Whatever methods you choose—whether you use ExoQuick or density gradient ultracentrifugation, want qPCR-based exosomal miRNA profiling or RNA-Seq methods—we’ve got the high-quality exosome research products to support your science and advance your work.

Lentivirus Production 

Whatever type of cell you’re trying to transduce, from 293T cells to the more difficult types like T cells and B cells, quality matters. Which is why SBI offers optimized virus packaging systems and reagents that can help you reliably obtain high titer preparations and efficient transfection and transduction.

Stable Cell Lines

Whether you need a reporter, fluorescent, overexpression, or other type of cell line, SBI has the technology and an expert team experienced in working with various cell lines for different research applications. 

Gene Expression Systems

Get access to a wealth of options for gene delivery and expression. SBI has the gene expression vectors to support a wide variety of projects. We offer viral and non-viral systems that can integrate into the genome or remain episomal as well as inducible systems for highly controlled expression.
