Biotin NTA, also known as BNTA (Biotin nitrilotriacetic acid, tripotassium salt) is used to detect histidine-tagged proteins (as little as 0.1 pmol) immobilized on nitrocellulose membranes. Biotin NTA can be removed from the histidine-tagged protein at pH 4.8, allowing the blot be reanalyzed with another probe. <ul> <li>White solid soluble in water</li> <li>Store at 4°C</li> <li>C₂₀H₃₆N₄O₈S</li> <li>MW: 488.56</li> </ul>
