摘要:
A first aspect of the invention relates to a non-covalently-HaloTag- binding compound characterized by the general formula D-L-T (I), wherein D is or comprises a fluorescent dye Z, wherein Z is L is a linear linker of 10-15 atoms in length, and T is a moiety selected from the group comprising methylamine, methylsulfonamide, acetamide, or their respective fluorinated analogues, azide, or hydroxyl. Another aspect of the invention relates to a HaloTag variant wherein position D106 of the HaloTag7 sequence is exchanged for a proteinogenic amino acid different from D. The variant has a different binding specificity for HaloTag substrates compared to the non- variant Halotag polypeptide. Yet another aspect of the invention relates to kits comprising polypeptides or nucleic acids and the non-covalently-HaloTag-binding compound according to the invention.
