Optimization of Adsorption Conditions for Dye-Ligand Affinity Chromatography Protocol Protocol for the optimization of absorption condition for dye-ligand affinity chromotography. Generally, low pH and low ionic strength, absence of phosphate ions, and the presence of divalent metals ions increase the binding of proteins to immobilized triazine dyes.
Optimization of Elution Conditions for Dye-Ligand Affinity Chromatography Protocol Protocol for the optimization of elution condition for dye-ligand affinity chromotography. Elution methods used in dye-ligand affinity chromatography may be either selective or nonselective in nature. Usually, selective elution methods are applied in combination with group-specific adsorbents, such as dye-ligand adsorbents, and nonselective elution methods are used in combination with highly specific adsorbents.
Preparation of Affinity-Ligand Resins by Immobilization of Dyes on Polyhydroxyl Matrices Triazine dyes, such as Cibacron Blue 3GA, can be linked to a hexyl spacer arm and then immobilized on a polyhydroxyl support matrix that has been activated with either 1,1-carbonyldiimidazole or epichlorohydrin. An alternative procedure for immobilizing dyes using the direct coupling method is provided in Immobilization of Dyes on Polyhydroxyl Matrices Using the Direct Coupling Method.
Purification of Protein Using Dye-Ligand Affinity Chromatography Protocol Protocol describes a general method for the purification of protein using dye-ligand affinity chromatography. The effectiveness of this protocol is dependent upon the reader having previously determined the optimal dye and buffer conditions to use for binding and eluting the protein(s) of interest.
Screening Immobilized Dyes for their Ability to Bind a Target Protein Protocol Protocol for screening immobilized dyes for their ability to bind a target protein. The selection of a dye adsorbent for the purification of the target protein is an empirical undertaking and is generally achieved by a trial-and-error approach.
