Proteinlerin saflaştırılması, herhangi bir biyokimyasal proteinler ya da yapısal çalışmalar içinde önemli bir adımdır. Her protein kendi davranışları ile benzersiz olduğu için, onun özelliklerini tanımlamak ve buna göre arıtma değiştirmek gerekiyor. Protein hedef biyoinformatik araçlar kullanarak arıtma doğru bir ilk adım olarak analiz edilmelidir. Onlar, hedef iso-elektrik nokta hesaplamak için çevre ve özel iyonları / ligandlar için ihtiyacı azaltıcı / oksitleyici ihtiyacı değerlen...
