pSNAPf-H2B Control Plasmid

  • Product Information
    This control plasmid contains the gene encoding the Histone H2B protein cloned upstream of the SNAPf coding sequence in pSNAPf, as a fusion to the N- terminus of the SNAP-tag. Histone H2B is a member of the core histones that package DNA in the nucleus. The H2B-SNAPf fusion protein gives nuclear fluorescence when labeled with SNAP-Cell® substrates. The full sequence and map for pSNAPf-H2B can be downloaded.

    The SNAP-tag is a novel tool for protein research, allowing the specific, covalent attachment of virtually any molecule to a protein of interest. The SNAP-tag is a small protein based on human O6-alkylguanine-DNA-alkyltransferase (hAGT). SNAP-tag substrates are derivatives of benzylguanines and benzylchloropyrimidines. In the labeling reaction, the substituted benzyl group of the substrate is covalently attached to the SNAP-tag. 

    pSNAPf -H2B contains an improved version of SNAP-tag, termed SNAPf. SNAPf displays faster kinetics in in vitro labeling and fast, specific and efficient labeling in live and fixed cell applications, thereby rendering it a desired research tool for analysis of protein dynamics.

    There are two steps to using this system: sub cloning and expression of the protein of interest as a SNAPf fusion, and labeling of the fusion with the SNAP-tag substrate of choice. Expression of the SNAPf -H2B fusion protein is described in this document. The labeling of fusion proteins with SNAP-tag substrates is described in the instructions supplied with SNAP-tag substrates.

    Live COS-7 cells transiently transfected with pSNAPf-H2B. Cells were labeled with SNAP-Cell® TMR-Star (red) for 15 minutes.
