Enterokinase (Recombinant) is highly purified recombinant bovine enterokinase obtained from E. Coli. Enterokinase is highly specific serine protease that hydrolysis peptide bond at the carboxyl side of lysine residue preceded by four aspartic acids (FLAG-tag). Enterokinase is used for removal ..

Ficin (or Ficain) is a cysteine protease enzyme (EC 3.4.22.3) isolated from fig latex is that has the endopeptidase activity to cleave immunoglobulin G molecules in the hinge reason. Ficin is typically used to cleave mouse IgG1 as this are difficult to cleave with papain and pepsin. In the..

Papain is a cysteine protease enzyme (EC 3.4.22.2) that has the endopeptidase activity to cleave immunoglobulin G molecules in the hinge region.  This cleavage results in the generation of three ~50kDa fragments; two Fab domains and a Fc domain.  The papain-digested antibody is unable to p..
$0.00
Pepsin is a proteolytic enzyme that is routinely used for the generation of F(ab)2 fragments from immunoglobulin G (IgG).  The pepsin has the ability to cleave the heavy chains near the hinge region. One or more of the disulfide bonds that join the heavy chains in the hinge region are preserved..
$0.00
Immobilized Trypsin is TPCK Treated Trypsin immobilized on 4% agarose that eliminates the contamination of protein digests by the trypsin.  The immobilized trypsin is readily removed by separating the agarose from the digestion solution.   Trypsin is a serine endopeptidase that specific..

SG-Carboxypeptidase B (Recombinant)™is the rat carboxypeptidase B expressed in E. coli. Carboxypeptidase B specifically hydrolyses basic amino acids including lysine, arginine and histidine from the C-terminal end of polypeptides.  It is used in sequencing protein and peptides. Other app..

SG-Chymotrypsin (Human, Recombinant)™ is recombinant human chymotrypsin expressed in E. coli and purified by HPLC method. Chymotrypsin hydrolysis at the carboxyl side of aromatic amino acid residues including Tyrosine, phenylalanine and Tryptophan. Cleavage occurs at lower rate at Leucine and..
$0.00
SG-Chymotrypsin™ is a serine endopeptidase, which predominantly cleaves peptide bonds on the carboxy side of tyrosine, phenylalanine and tryptophan. In addition, chymotrypsin has a low catalytic activity against the carboxy side of leucine, methionine, alanine, aspartic and glutamic acids. It ..
$0.00
SG-Glutamic-C™ is a serine endopeptidase, from S. aureus V8, that is highly specific for the cleavage of peptide bonds at the carboxy side of either aspartic or glutamic acid, depending on the buffer used. In Tris-HCl buffer, in particular in the absence of phosphate ions, the enzyme is specif..
$0.00
SG-Lysine-C™ endopeptidase, from Lysobacter enzymogenes, is a serine protease highly specific in cleaving peptide bonds at the carboxy side of lysine. Highly purified preparations of SG-Lysine-C™ are chemically modified making the enzyme resistant to autolysis and stabilizing its enzymat..
