rProtein A-Cys (4xZc)

  • rProtein – Cys (4xZc) is a variant of rProtein A (4xZ) in which the C – terminal residue has been replaced with a cysteine residue that can be used for single-point coupling to solid supports, via thioether bond, to produce affinity media suitable for antibody capture and elution. Like rProtein A (4xZ), rProtein A – Cys (4xZc) can also be attached to solid supports via multi-point coupling. rProtein A – Cys (4xZc) is produced by recombinant expression in E. coli and purified using a highly efficient, immunoglobulin – free process. rProtein A – Cys (4xZc) contains four identical copies of an Fc region – binding domain assembled in a single 29.87 kDa polypeptide.
