β Lactamase/ 重组beta内酰胺酶
产品编号：ENZ-351
产品规格：1mg/10mg/50mg
Synonyms β-Lactamase, EC 3.5.2.6, Cephalosporinase. Introduction Beta-lactamase is a type of enzyme （EC 3.5.2.6） produced by some bacteria that is responsible for their resistance to beta-lactam antibiotics like penicillins, cephalosporins, cephamycins ａnd carbapenems. These antibiotics have a common element in their molecular structure: a four-atom ring known as a beta-lactam. The lactamase enzyme breaks that ring open, deactivating the molecule＇＇s antibacterial properties. Description Beta-Lactamase Recombinant produced in E.Coli is a single, non-glycosylated polypeptide chain containing 263 amino acids ａnd having a molecular mass of 29 kDa. Beta Lactamase is purified by proprietary chromatographic techniques. Source Escherichia Coli. Physical Appearance Sterile Filtered White lyophilized （freeze-dried） powder. Formulation Lyophilized from a concentrated （1 mg/ml） solution in water containing 20mM Phosphate buffer pH⁻⁷. Solubility It is recommended to reconstitute the lyophilized Beta Lactamase in sterile 18MΩ-cm H2O not less than 100 μg/ml, which can then be further diluted to other aqueous solutions. Stability Lyophilized Beta Lactamase although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution Beta Lactamase Recombinant should be stored at 4°C between 2⁻⁷ days ａnd for future use below -18°C. For long term storage it is recommended to add a carrier protein （0.1% HSA or BSA）. Please prevent freeze-thaw cycles. Purity Greater than 90.0% as determined by: （a） Analysis by RP-HPLC. （b） Analysis by SDS-PAGE. Amino acid sequence MHPETLVK VKDAEDQLGA RVGYIELDLN SGKILESFRP EERFPMMSTF KVLLCGAVLS RVDAGQEQLG RRIHYSQNDL VEYSPVTEKH LTDGMTVREL CSAAITMSDN TAANLLLTTI GGPKELTAFL HNMGDHVTRL DRWEPELNEA IPNDERDTTM PAAMATTLRK LLTGELLTLA SRLIDWME ADKVAGPLLR SALPAGWFIA DKSGAGERGS RGIIAALGPD GKPSRIVVIY TTGSQATMDE RNRQIAEIGA SLIKHW. Unit Definition One unit will hydrolyze 1.0 μmole of indicated substrate per min at pH 7.0 at 25°C. The International Unit （using benzylpenicillin as substrate） is approximately equal to 600 Levy or 75 Pollock units. Specific Activity 1,500IU/mg. Usage Prospec＇s products are furnished for LABORATORY RESEARCH USE ONLY. They may not be used as drugs,agricultural or pesticidal products, food additives or household chemicals.

产品规格：1mg/10mg/50mg
Synonyms β-Lactamase, EC 3.5.2.6, Cephalosporinase. Introduction Beta-lactamase is a type of enzyme （EC 3.5.2.6） produced by some bacteria that is responsible for their resistance to beta-lactam antibiotics like penicillins, cephalosporins, cephamycins ａnd carbapenems. These antibiotics have a common element in their molecular structure: a four-atom ring known as a beta-lactam. The lactamase enzyme breaks that ring open, deactivating the molecule＇＇s antibacterial properties. Description Beta-Lactamase Recombinant produced in E.Coli is a single, non-glycosylated polypeptide chain containing 263 amino acids ａnd having a molecular mass of 29 kDa. Beta Lactamase is purified by proprietary chromatographic techniques. Source Escherichia Coli. Physical Appearance Sterile Filtered White lyophilized （freeze-dried） powder. Formulation Lyophilized from a concentrated （1 mg/ml） solution in water containing 20mM Phosphate buffer pH⁻⁷. Solubility It is recommended to reconstitute the lyophilized Beta Lactamase in sterile 18MΩ-cm H2O not less than 100 μg/ml, which can then be further diluted to other aqueous solutions. Stability Lyophilized Beta Lactamase although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution Beta Lactamase Recombinant should be stored at 4°C between 2⁻⁷ days ａnd for future use below -18°C. For long term storage it is recommended to add a carrier protein （0.1% HSA or BSA）. Please prevent freeze-thaw cycles. Purity Greater than 90.0% as determined by: （a） Analysis by RP-HPLC. （b） Analysis by SDS-PAGE.

Unit Definition One unit will hydrolyze 1.0 μmole of indicated substrate per min at pH 7.0 at 25°C. The International Unit （using benzylpenicillin as substrate） is approximately equal to 600 Levy or 75 Pollock units. Specific Activity 1,500IU/mg.

Solubility It is recommended to reconstitute the lyophilized Beta Lactamase in sterile 18MΩ-cm H2O not less than 100 μg/ml, which can then be further diluted to other aqueous solutions. Stability Lyophilized Beta Lactamase although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution Beta Lactamase Recombinant should be stored at 4°C between 2⁻⁷ days ａnd for future use below -18°C. For long term storage it is recommended to add a carrier protein （0.1% HSA or BSA）. Please prevent freeze-thaw cycles. Purity Greater than 90.0% as determined by: （a） Analysis by RP-HPLC. （b） Analysis by SDS-PAGE.

β Lactamase/ 重组beta内酰胺酶
产品编号：ENZ-351
产品规格：1mg/10mg/50mg
Synonyms β-Lactamase, EC 3.5.2.6, Cephalosporinase. Introduction Beta-lactamase is a type of enzyme （EC 3.5.2.6） produced by some bacteria that is responsible for their resistance to beta-lactam antibiotics like penicillins, cephalosporins, cephamycins ａnd carbapenems. These antibiotics have a common element in their molecular structure: a four-atom ring known as a beta-lactam. The lactamase enzyme breaks that ring open, deactivating the molecule＇＇s antibacterial properties. Description Beta-Lactamase Recombinant produced in E.Coli is a single, non-glycosylated polypeptide chain containing 263 amino acids ａnd having a molecular mass of 29 kDa. Beta Lactamase is purified by proprietary chromatographic techniques. Source Escherichia Coli. Physical Appearance Sterile Filtered White lyophilized （freeze-dried） powder.
