pESC Yeast Epitope Tagging Vectors
These vectors also feature an extensive polylinker sequence and the ability to generate end-specific RNA transcripts from T3 and T7 promoters. Each of the pESC vectors contains one of four different yeast-selectable markers (HIS3, TRP1, LEU2, or URA3) in the same vector backbone.
The pESC vectors contain DNA sequences coding for epitope peptides that can be specifically recognized by monoclonal antibodies. A sequence for the FLAG® epitope (DYKDDDDK) is located in the multiple cloning site (MCS) downstream of the GAL10 promoter.
A sequence for the c-Myc epitope (EQKLISEEDL) is located in the MCS downstream of the GAL1 promoter. You can insert your gene of interest in front of the epitope sequence to generate C-terminal tagging or after the epitope sequence for N-terminal tagging. These tags allow the protein of interest to be studied without generating a specific antibody to that protein. The epitope-tagged fusion proteins can be studied in transformed cells using well-characterized antibodies.
