WebbHere are some key points to get you started using MabSelect™ PrismA protein A resin to purify most mAbs and many mAb-derived entities. See Table 1 for general guidelines. But first, you'll need to prepare your sample for loading: Load preparation. Before you load your sample onto a column, clarify it using a sterile filter. WebbProtein can be eluted either by a linear gradient elution or using a step isocratic elution. Often, a gradient elution may be used to optimize elution conditions. Once the elution profile of the protein of interest has been established and it is known at what ionic strength or pH a protein elutes, a step elution can be used to speed the purification process.

WebbFirst, the salt concentration in the elution buffer is gradually increased. The negative ions in the salt solution (e.g. Cl − ) compete with protein in binding to the resin. Second, the pH of the solution can be gradually decreased which results in a more positive charge on the protein, releasing it from the resin.
