For new and developing protein classes, there is the kbDNA Miscellaneous library. This index is a helpful introduction for diverse recombinant taxonomies such as protease inhibitors, annexins, Superoxide Dismutase, FC Receptors, Glycobiology Enzymes and more. As these individual categories grow in both quantity and expertise they will develop into their own specialty libraries. Additional data, including QC, which is not available directly on target pages may be available upon request.
