What is the fold purification?

Fold purification refers to the number of times a protein preparation is enriched for the protein being purified.

Consequently, how is fold purification calculated?

Purification (fold) – ìFoldî refers to the number of multiples of a starting value. In this case it refers to the increase in the specific activity, i.e. the purification is obtained by dividing the specific activity at any stage by the specific activity of the original homogenate.

what does purification factor mean? A measure for the relative purity of a fraction (x) is the purification factor; it is defined as: specific activity of (x) ______________________________ = purification factor for (x) specific activity of starting material.

Beside this, why does fold purification increase?

The specific activity is much higher at the end of purification because your protein is much purer (it's the activity per total protein). The fold purification is higher because most of the protein left at the end is the one you want.

What are protein purification techniques?

Protein purification is a series of processes intended to isolate one or a few proteins from a complex mixture, usually cells, tissues or whole organisms. Separation steps usually exploit differences in protein size, physico-chemical properties, binding affinity and biological activity.
