abstract |
The present invention relates to polypeptide tags that can be used for the isolation, purification and detection of polypeptides. The present invention relates in particular to expression vectors which encode a fusion polypeptide which comprises a tag54 epitope and a desired polypeptide, and to the use of such expression vectors for expressing the fusion polypeptides. Furthermore, the invention relates to antibodies against the fusion peptides generated with the described polypeptide tag, their use for the isolation, purification and detection of the fusion peptides, and the kits suitable for this purpose. |
