Polyclonal anti-V5 (GKPIPNPLLGLDST) is designed to detect V5 tagged fusion proteins. The V5 epitope tag is derived from a small epitope (Pk) present on the P and V proteins of the paramyxovirus of simian virus 5 (SV5). The antibody recognizes the epitope tag fused to either the amino- or carboxy- termini of targeted proteins. This product is prepared by labeling high quality polyclonal rabbit anti-V5 IgG (H+L) with the green fluorescent dye CF™488A. CF™488A is a superior alternative to the traditional green fluorescent dye FITC (or fluorescein) owing to its exceptional brightness and photostability. CF™488A has brightness and photostability comparable to Alexa Fluor® 488.
