Purification of a recombinant protein with cellulose-binding module 3 as the affinity tag

Methods Mol Biol. 2014;1177:35-45. doi: 10.1007/978-1-4939-1034-2_3.


Easy-to-perform and low-cost protein purification methods are in high demand for the mass production of commonly used enzymes that play an important role in bioeconomy. A low-cost and rapid recombinant protein purification system was developed using CBM3 (family 3 cellulose-binding module) as affinity tag. This protocol describes the purification of CBM3-fusion protein and tag-free protein expressed in Pichia pastoris using CBM3 as an affinity tag.
