HY-P2823

Trypsinogen	Biochemical Assay Reagents
Trypsinogen, a proenzyme synthesized in the pancreas, is activated to form trypsin by enterokinase upon reaching the small intestine lumen, where it opens a hexapeptide bond at the Lys6 - Ile7 junction, leading to the production of the active enzyme. This single polypeptide chain, composed of 229 amino acids and stabilized by six disulfide bridges, further autocatalytically converts additional trypsinogen into trypsin, which is initially present as β-trypsin before undergoing autolysis at the Lys131 - Ser132 site to form α-trypsin. As a serine protease, trypsin features His46 and Ser183 at its active site and exhibits optimal enzymatic activity at a pH range of 7 to 9.

HY-P0223A

FLAG peptide TFA 10+ Cited Publications	Peptides	Others
FLAG peptide TFA is the TFA salt form of FLAG peptide (HY-P0223). FLAG peptide TFA is a multifunctional fusion tag for the purification of recombinant proteins. FLAG peptide TFA maintances the natural folding of its fusing proteins. FLAG peptide TFA can be removed by enterokinase, and eluted under non-denaturing conditions .

HY-P0329

X-press Tag Peptide	Peptides	Others
X-press Tag Peptide is a tag peptide used for protein purification. X-press Tag is also an N-terminal leader peptide; this N-terminal peptide contains a polyhistidine sequence, the Xpress epitope (part of bacteriophage T7 gene 10 protein) and an enterokinase cleavage site. Anti-Xpress antibodies recognize the Xpress epitope sequence found in this leader peptide.

HY-P7341

	Enterokinase Protein, Bovine (P.pastoris, His) rBoEnterokinase, His; Enteropeptidase; ENTK; PRSS7	Bovine	P. pastoris
	Enterokinase Protein, Bovine (P.pastoris, His) is a single glycosylated polypeptide chain with His tag. Enterokinase plays a role of turning trypsinogen to its active form trypsin.

HY-P7341AF

	*Animal-Free Enterokinase* Protein, Bovine (His)** Enteropeptidase; Enterokinase; Serine protease 7; Transmembrane protease serine 15; Enteropeptidase; ENTK; PRSS7	Bovine	P. pastoris
	Enterokinase proteins play a key role in initiating the activation of pancreatic proteolytic enzymes, including trypsin, chymotrypsin, and carboxypeptidase A. Its catalytic function converts trypsinogen to trypsin, triggering the cascade activation of chymotrypsinogen, procarboxypeptidase, and tropoelastin. Animal-Free Enterokinase Protein, Bovine (His) is the recombinant bovine-derived Enterokinase, expressed by P. pastoris , with C-His labeled tag. The total length of Animal-Free Enterokinase Protein, Bovine (His) is 235 a.a.,
