Spectrum: A Repligen Brand is a Rancho Dominguez, California-based biotechnology company that provides membrane-based separation solutions for pharmaceutical development, bioprocessing, diagnostics, and life sciences research. It centers on two core approaches: single-use hollow fiber tangential flow filtration and tubular membrane dialysis. Its historical work includes the development of cellulosic dialysis membranes across a range of molecular weight cut-offs for gentle protein purification, desalting enzymes, and sample preparation, sold under the Spectra/Por brand.

Since 1995, Spectrum has produced hollow fiber filters for purification and concentration of biopharmaceuticals and diagnostic particles, expanding to a wide range of hollow-fiber chemistries for ultrafiltration, nanofiltration, and microfiltration used in upstream and downstream filtration. The company markets its products globally through direct sales in the United States, Europe, and Asia, with additional reach through strategic partnerships. A recent development is Repligen's opening of a Training & Innovation Center in Breda, Netherlands, expanding its European customer support network.
