3x DYKDDDDK Tag TFA 

Cat. No.: HY-P3332A
Handling Instructions

DYKDDDDK peptide (FLAG) is a useful tool for investigating the function and localization of proteins whose antibodies (Abs) are not available. Often it is also used in a 3X FLAG format (3x DYKDDDDK Tag TFA) for purifying difficult proteins that accumulate in low abundance .

Description

DYKDDDDK peptide (FLAG) is a useful tool for investigating the function and localization of proteins whose antibodies (Abs) are not available. Often it is also used in a 3X FLAG format (3x DYKDDDDK Tag TFA) for purifying difficult proteins that accumulate in low abundance [1][2].

In Vitro

HEK293 cells transiently transfected with HARS-expressing plasmids were harvested and lysed in CelLytic M buffer containing mammalian protease inhibitor cocktail for 20 min at 4 °C. FLAG-tagged HARS is purified by binding to an anti-DYDDDDK resin per manufacturer protocol and eluted by competition with 3X-DYKDDDDK peptide in buffer containing 50 mM Tris-HCl pH 7.4, and 150 mM NaCl (purification of human HARS)[2].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.

The dilution calculator equation

Concentration (start) × Volume (start) = Concentration (final) × Volume (final)

This equation is commonly abbreviated as: C1V1 = C2V2

Concentration (start) × Volume (start) = Concentration (final) × Volume (final)
