Digoxigenin binding protein (DigA)

This part is a synthetic protein called "anticaline" which is derived from the naturally existing protein lipocaline. It is able to bind antigen and therefore functions as a linker to another part/protein, which is labeled with digoxigenin.

Usage and Biology

Normally a digoxigenin antibody is used for Nonradioactive in situ hybridization.
We used this part to connect our universal restriction endonuclease protein domains to digoxigenin labeled oligos. These oligos were hybridized with ssDNA and so they made a connection between the protein and the DNA. Another possiblity is to use TFO's (triplex-forming oligonucleotides) labeled with digoxigenin to establish a connection between dsDNA and protein.
