WebbDescription. Ni-NTA Agarose is a nickel-charged affinity resin that can be used to purify recombinant proteins containing a polyhistidine (6xHis) sequence. Proteins bound to … WebbGenerally nickel resin gives the highest rate. A recombinant protein for a 6xHis tag has a high affinity in nickel, whereas most other proteins will either bind with low relative, or not at all. Nonspecific obliging due to electrostatic attraction to the nickel beads can must minimized on addition in NaCl the the ladungen buffer.

Webb13 apr. 2024 · Specifically, a single-labeled peptide with oligohistidine-tag (His-tag) was designed as the protease substrate, which can be captured by a nickel ion-nitrilotriacetic acid (Ni-NTA)-conjugated magnetic nanoparticle (MNP) through the coordination interaction between His-tag and Ni-NTA. WebbHis-tag Purification. His-tag purification is a vital part of modern research. Impure extracts generally contain a wide range of proteins with diverse biological functions and … WebbThis His-tag binds tightly to the immobilized metal ions because the side chain of Histidine, imidazole, has a specific binding affinity to metal ions (in this case, nickel II).
