Stable Recombinant Carboxypeptidase B E.coli Carboxypeptidase B E.coli

Carboxypeptidase B (or peptidyl-L-lysine (-L-arginine) hydrolase) catalyzes the hydrolysis of the basic amino acids, lysine, arginine, and ornithine from the C-terminal position of polypeptides. It has been shown to be a single polypeptide of 33.8 kDa. Trypsin is capable of converting native enzyme to the active enzyme, carboxypeptidase B II in vitro. The optimum pH is found to be 9.0. The enzyme may be used for sequence analysis by successive cleavage of C-terminal basic amino acids. It can also be used as a serum marker for the diagnosis of acute pancreatitis.

Animal origin free:YaxinBio recombinant carboxypeptidase B belongs to the AOF level 3, eliminate the risk of virus presence, or any other potential adventitious agents found in animal-derived carboxypeptitase B

Stability:A sterile recombinant carboxypeptidase B lyophilized eliminates the risk of contamination and decreases the chances of activity loss in the process of transport and storage.

High purity:

1) Recombinant carboxypeptidase B provides increased specific activity and eliminates contaminating proteases activities found in extracted enzymes with lower purity level.

2) No other contaminating proteases such as chymotrypsin and carboxypeptidase A.

3)Less than 10ppm of recombinant trypsin.

Unit Definition

One Unit of carboxypeptidase B activity hydrolyzes one micromole of hippuryl-L-arginine per minute at 25℃, pH 7.65.

Recommend Usage

To prepare 1-10mg/ml carboxypeptidase B with sterile water or 25mM Tris-HCl pH 7.65. The ratio to aimed protein is 1:50 to 1:1000 (w/w), the optimum pH is pH 7-9.

Storage Instructions

Recommend recombinant carboxypeptidase B lyophilized should be stored under 2℃-8℃ in sealed container. It is stable within 24 months.After dissolved, it should be stored under -20℃, It is stable within 24 months and above 90% activity remained after 10 times repeated freezing and thawing.
