Thermo Scientific™ Immobilized Papain (Agarose Resin)

Generate and purify Fab fragments from antibodies with cysteine-endopeptidase papain immobilized onto beaded agarose resin.

2

Thermo Scientific™ Immobilized Ficin (Agarose Resin)

Enable controlled antibody fragmentation, especially of mouse IgG1, with this sulfhydryl-specific ficin protease immobilized onto beaded agarose resin.

3

Thermo Scientific™ Immobilized Trypsin, TPCK Treated (Agarose Resin)

Cleave the carboxyl-side of Arg and Lys residues with trypsin that isTPCK-treated to block chymotrypsin activity; its immobilized form allows enzyme removal after digestion.

4

Thermo Scientific™ Immobilized Pepsin (Agarose Resin)
