Sequencing Grade Carboxypeptidase B

Catalog Number:SRCPB01

CAS:9025-24-5
EC:3.4.17.2

Storage temperature: 2-8鈩

Source: Sequencing grade recombinant carboxypeptidase B is a genetically engineered protein expressed in E.coli 

Protein Sequence:The amino acid sequence of recombinant carboxypeptidase B is identical to rat carboxypeptidase B

 

1.DESCRIPTION

Carboxypeptidase B catalyzes hydrolysis of the basic amino acids lysine, arginine and histidine from the C-terminal end of polypeptides. The molecular weight is 33.8kD, pI is 6.0 and the optimum pH is 7.5-9.0. Carboxypeptidase B is competitively inhibited by arginine and lysine. The enzyme is also inhibited by metal chelating agents, e.g., EDTA.

 

2. MAIN FEATURES

Source

Recombinant E. coli

Appearance

White or off white, or yellowish powder

Specific activity

≥200 units/mg pro.

SDS-PAGE

Single major band

Molecular Weight(SDS-PAGE)

 33.8±3.4 kDa

Purity(HPLC)

≥ 95%

 

3.RECOMMEND USAGE 

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 7.5-9.0. 

 

4.STABILITY OF STORAGE AND TRANSPORT

Stability of storage: Sequencing grade carboxypeptidase B lyophilized should be stored under 2-8鈩 in sealed container.

It is stable within 24 months.

After dissolved with sterile water or 25mM Tris-HCl, it should be stored under -20鈩. 

Avoid repeated freezing and thawing.

Stability of transport: The product is stable by blue ice insulation transport.

 

5.PRODUCT ADVANTAGE

  1. Sequence grade recombinant protein: high specificity,good stability.
  2. Animal origin free: Sequencing grade carboxypeptidase B is no exogenous virus contamination,and any animal origin material is not used in the production process.
  3. Stable quality: Mass production can ensure stable and continuous batch production.It is no difference between the batch and the product quality is stable.
  4. High purity: Higher specific activity.Host protein residues is less than the limits of biological products.
  5. Lyophilized powder: The product is lyophilized powder and is easy to store and transport.
  6. Compliance with regulatory requirements: Production equipment and production environment comply with relevant regulatory requirements, and the production process is in full compliance with NSF ISO 9001: 2008 quality system and GMP guidelines.
  7. Complete quality documents: we can provide relevant regular support files in according to customers’ requirement.

 

6.PRODUCT USAGE

1) Determination of protein C-terminal basic amino acids such as arginine, lysine and histidine.

2) detection of antibody basic peak.
