Intein tag purification
NettetInteins can be engineered for use as self-cleaving tags for the purification of recombinant proteins. By mutating critical residues, inteins can be modified to perform N- or C-terminal cleaving reactions in ... developed intein-based purification systems. We focus on the use of contiguous, artificially-split, and Netteti CapTag™ ( intein Cap ture Tag ), peptide-based a self-removing tag controlled by pH change (MIKIATRKYLGKQNVYGIGVERDHNFALKNGFIAHN). Its patented component derived from Nostoc punctiforme (Npu) intein. This tag is used for protein purification of recombinant proteins and its fragments.

Nettet5. des. 2013 · Tag removal, which is often a necessary step for recombinant proteins purified by affinity tags, is usually accomplished using site-specific protease enzymes. Protease costs and the additional separation of the cleaved tag and protease from the final products have hindered the use of this method for many applications. Nettet1. jan. 2024 · Initial tests with shake flask cultures confirmed that the intein purification scheme could be scaled down, with >90% pure product generated in a single step using both methods. The scheme was then validated in a high throughput expression platform using 24-well plate cultures followed by purification in 96-well plates.
Nettet1. mar. 2012 · Ubiquitin-intein and SUMO2-intein fusion tags were constructed. Both tags enhance the expression of eGFP and solubility of eGFP and MMP13. Both tags allowed convenient purification of eGFP with high homogeneity. Both tags may present viable alternatives for protein production in industry process. Introduction
