PK-TAG
MaxLight™650 is a new Far-IR stable dye conjugate comparable to Alexa Fluor™647, DyLight™649, Cy5™ and offers better labeling efficiency, brighter imaging and increased immunodetection. Absorbance (655nm); Emission (676nm); Extinction Coefficient 250,000.
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 V5 tag is usually used with all 14 amino acids (GKPIPNPLLGLDST), although it has also been used with a shorter 9 amino acid sequence.
The V5 epitope tag is a small epitope, termed Pk, present on the P/V proteins of the paramyxovirus, SV5.

Storage and Stability
Store product at 4°C in the dark. DO NOT FREEZE! Stable at 4°C for 12 months after receipt as an undiluted liquid. Dilute required amount only prior to immediate use. Further dilutions can be made in assay buffer. Caution: MaxLight™650 conjugates are sensitive to light. For maximum recovery of product, centrifuge the original vial prior to removing the cap.
Note: Applications are based on unconjugated antibody.
Immunogen
Paramyxovirus SV5, Simian-Virus 5.
Form
Supplied as a liquid in PBS, pH 7.2. Labeled with MaxLight™650.
Purity
Purified by Protein A affinity chromatography from tissue culture supernatant.
Specificity
Recognizes the V5 epitope tag. Detects recombinant proteins tagged with the epitope, some of which include transmembrane and secreted proteins. Usually, a 14aa tag is added to the recombinant proteins, although a smaller epitope of 9aa (that as a peptide inhibit the binding of the monoclonal antibody to its native protein) has also been successfully used. The 14 amino acid epitope is; gly lys pro ile pro asn pro leu leu gly leu asp ser thr. (The 9 amino acid epitope is underlined).
