Well-characterized antibodies for epitope tags have been widely used in the study of protein expression in various systems. The SNAP-Tag is a self-labeling protein tag that forms a highly stable, covalent thioether bond with fluorophores and other substituted groups on its benzyl guanine substrate. The expressed SNAP-tag fusion proteins can be used in many different assay formats depending upon the labeling substrate employed. Applications: Suitable for use in ELISA and Western Blot. Other applications not tested. Recommended Dilution: ELISA: 0.05-0.2ug/ml, Western Blot: 0.1-1.0ug/ml, Optimal dilutions to be determined by the researcher.
