Recombinant Kex2 Protease
This recombinant Kex2 product is produced via expression in Pichia pastoris and carries a His-tag. It exhibits efficient catalytic activity at pH 7.0–9.0 (optimal at 37 °C), retains high stability under mildly acidic conditions (pH 5.0–6.0), and is well-suited for manufacturing recombinant GLP-1 receptor agonist therapeutics and other polypeptide products.

Recombinant Carboxypeptidase B
This recombinant carboxypeptidase B product is produced via microbial fermentation and heterologous expression in either Escherichia coli or Pichia pastoris, supplied without a His-tag fusion, and exhibits optimal catalytic activity at pH 7.5–9.0. It is ideally suited for manufacturing recombinant insulin and its analogs, GLP-1 receptor agonist therapeutics, and a broad range of other recombinant polypeptide products.

Recombinant Enterokinase
This product is a highly purified recombinant preparation of the bovine enterokinase light chain with strict target sequence specificity, free of contaminating non-specific protease activities, and maintains efficient cleavage performance across a pH range of 4.5–9.5 and temperature range of 4–45 °C.

Endo H
Endoglycosidase H is a recombinant glycosidase cloned from Streptomyces plicatus that specifically cleaves the chitobiose core of high-mannose and select hybrid-type N-glycans on glycoproteins, enabling efficient removal of high-mannose glycans from glycoprotein substrates.

Endonuclease V
Endonuclease V is a DNA repair enzyme originally identified in Escherichia coli that specifically recognizes deoxyinosine residues in DNA — the deamination product generated by spontaneous deamination of deoxyadenosine.

Sortase A
Sortase A is a bacterial-derived transpeptidase that catalyzes transamidation reactions for precise, site-specific covalent attachment of functional moieties onto protein substrates.
View Details
Endo S
Endoglycosidase S is an endoglycosidase with strict substrate specificity that selectively cleaves the chitobiose core of N-glycans, enabling efficient removal of N-glycan moieties from the heavy chain of natively folded IgG molecules.

Alkaline Phosphatase（AP)
Alkaline phosphatase is a metalloenzyme that catalyzes the precise, site-specific removal of phosphate groups from target substrate molecules under alkaline conditions.

3C Protease
HRV 3C protease, originally derived from human rhinovirus type 14, is produced via heterologous expression in Escherichia coli and carries a His-tag.

Terminal deoxynucleotidyl transferase
Terminal deoxynucleotidyl transferase (TdT) is a template-independent DNA polymerase that catalyzes the addition of deoxynucleotides to the 3'-hydroxyl termini of DNA.

T4 Polynucleotide Kinase
T4 polynucleotide kinase catalyzes the transfer of the γ-phosphate group from ATP to the 5'-hydroxyl termini of oligonucleotides — including double- and single-stranded DNA and RNA — and to 3'-monophosphate nucleosides.

dsRNA Ligase
T4 RNA Ligase 2 is an ATP-dependent dsRNA ligase that mediates intermolecular and intramolecular ligation of RNA strands, efficiently seals nicks in double-stranded RNA substrates, and can catalyze ligation between the 3'-hydroxyl of an RNA strand and the 5'-phosphate of a DNA strand when both ends are positioned within a double-stranded nucleic acid duplex.
