Anti-V5 Antibody (18868) (18868-100ug)

The V5 epitope tag is a short, 14-amino acid peptide with the sequence GKPIPNPLLGLDST, originally derived from the RNA polymerase α subunit of simian parainfluenza virus 5 (SV5). Widely used in molecular biology and protein expression studies, the V5 tag enables efficient detection, purification, and localization of recombinant proteins. Due to its compact size, the V5 tag is less likely to disrupt the structure or function of the fusion protein, making it ideal for a variety of applications including Western blotting, immunoprecipitation (IP), and immunofluorescence or confocal microscopy. V5-tagged constructs are commonly used when antibody specificity, sensitivity, and minimal interference with native protein activity are critical.
