DYKDDDDK Tag Polyclonal Antibody, Invitrogen™

Descripción

PA1-984B detects the DYKDDDDK epitope tag sequence, similar to the FLAG tag from Sigma. PA1-984B has been successfully used in Western blot and immunofluorescence procedures to detect the presence of fusion proteins containing the epitope tag sequence DYKDDDDK. PA1-984B immunizing peptide corresponds to the epitope tag sequence DYKDDDDKC. This peptide (Cat. # PEP-087) is available for use in neutralization and control experiments.

DYKDDDDK tag, also known as FLAG tag, is a short peptide sequence that is commonly used as a protein tag to facilitate protein purification, detection, and localization. The tag consists of eight amino acids: Asp-Tyr-Lys-Asp-Asp-Asp-Asp-Lys. It is often fused to the N- or C-terminus of a protein of interest, allowing for easy identification and isolation of the protein using anti-FLAG antibodies. The DYKDDDDK tag is widely used in molecular biology and biochemistry research, and has been employed in various applications, such as protein-protein interaction studies, protein expression analysis, and protein localization studies. The FLAG tag structure has been optimized for compatibility with the proteins it is attached to, in that it is more hydrophilic than other common epitope tags and therefore less likely to denature or inactivate proteins to which it is appended.
