Biotin-X NTA (Biotin-X nitrilotriacetic acid, tripotassium salt) is used to detect histidine-tagged proteins (as little as 0.1 pmol) immobilized on nitrocellulose membranes. Biotin-X NTA can be removed from the histidine-tagged protein at pH 4.8, allowing the blot to be reanalyzed with another probe. <ul> <li>White solid soluble in water</li> <li>Store at 4°C</li> <li>C₂₆H₄₀K₃N₅O₉S</li> <li>MW: 715.98</li> </ul>
