CLIP-Surface™ 488

CLIP-Surface™ 488 is a photostable green fluorescent substrate that can be used to label CLIP-tag™ fusion proteins on the surface of living cells or in vitro.

  • This is a cell impermeable substrate (BC-488) based on ATTO-TEC dye ATTO 488
  • It is suitable for standard fluorescein filter sets
  • It has an excitation maximum at 506 nm and emission maximum at 526 nm

    This package includes 50 nmol of CLIP-Surface 488 substrate, sufficient to make 10 ml of a 5 µM CLIP-tag fusion protein labeling solution.

    The CLIP-tag protein labeling system enables the specific, covalent attachment of virtually any molecule to a protein of interest. CLIP-tag is a protein tag based on human O6-alkylguanine-DNA-alkyltransferase (hAGT). CLIP-tag substrates are derivatives of benzylcytosine (BC). In the labeling reaction, the substituted benzyl group of the substrate is covalently attached to the reactive cysteine of CLIP-tag forming a stable thioether bond. Although CLIP-tag is based on the same protein as SNAP-tag®, the benzylcytosine substrates form a separate class of substrates, different from the benzylcytosine substrates form a separate class of substrates, different from the benzylguanine substrates recognized by SNAP-tag. CLIP-tag and SNAP-tag can be used for orthogonal and complementary labeling of two proteins simultaneously in the same cells.

    There are two steps to using this system: subcloning and expression of the protein of interest as a CLIP-tag fusion, and labeling of the fusion with the CLIP-tag substrate of choice. Expression of CLIP-tag fusion proteins is described in the documentation supplied with CLIP-tag plasmids. The labeling of the fusion proteins on the cell surface with the CLIP-tag substrate is described in this document.
