Chitin Resin
An affinity matrix for the isolation of target proteins fused to an intein-chitin binding domain fusion
- Strong specific binding for CBD-fusion protein affords highly pure protein of interest from crude lysate in one step
- Removal of CBD-tag during elution typically yields highly pure, native protein without the use of a protease
- This resin, when used with pTXB1, allows for the isolation of native recombinant proteins possessing a reactive C-terminal thioester that can be used for applications in intein-mediated protein ligation (IPL) and site-specific labeling
- Binding capacity: 2 mg maltose-binding protein/mL bed volume released from the resin after cleavage of the maltose-binding-CBD-fusion protein
- Resin may be regenerated up to 5 times
