일반 설명
β-Lactamase is a monomeric enzyme of 29 kDa. This product is produced from Enterobacter cloacae and is provided as a lyophilized powder. It acts as a target protein for β-lactam antibiotics. This enzyme is present in Gram-negative bacteria.
애플리케이션
β--lactamase is used to inactivate β-lactam antibiotics by breaking open the β-lactam ring. β--lactamase is used to study antibiotic resistance and resistance suppression. Product P4524 is produced from Enterobacter cloacae and is provided as a lyophilized powder.
β-Lactamase from Enterobacter cloacae has been used in the maternal and fetal quantitative blood cultures to avoid any carryover phenomenon. It has also been used as a component in Mueller Hinton (MH) broth for placental cultures.
생화학적/생리학적 작용
β--lactamase inactivates β-lactam antibiotics by breaking open the β-lactam ring.
단위 정의
