PEG-NTA for His-tag PEGylation

MTO-NTA
PEG-NTA for His-tag (polyhistidine) PEGylation

Description

Nitrilotriacetic acid (NTA)-PEG conjugate in the form of a metal complex with Co colbat, Ni Nickel form a chelating complex with polyhistidine tag (His-tag). A polyhistidine-tag consists of at least six histidine (His) residues, often at the N- or C-terminus of the protein. His-tag synonyms: hexa histidine-tag, 6xHis-tag, His6 tag. His-tag is a registered Trademark of EMD Biosciences. His-tag is common to tag recombinant proteins for easy purification. PEG-NTA can effectively PEGylate polyhistidine tagged proteins for purification and other applications such as immobilizing proteins to a support (surface, particles, resins)..
