β-lactam Rapid test kit

Cat.No.: Kit-1898
Product Overview: The β-lactam Rapid test is based on the specific immune-chemical reactions between antigen and antibody. It relies on the competition between β-lactam residues in the sample and β-lactam immobilized on the T line on the membrane for the β-lactam antibody-dye conjugate. Since the drug is present in the sample, it will compete with the drug immobilized on the T line for the limited amount of dye-antibody. When sufficient amount of drug is present in the sample, it will saturate the antibody. Consequently, it will show an extremely light or even invisible T line, indicating a positive result. On the other hand, a negative sample (or when the drug is lower than the minimum detectable concentration, 2 ppb) will generate two visible lines in both the T and C line sections.
Description: The β-lactam ring is an important part of core structure of several antibiotic families, such as penicillins, cephalosporins, carbapenems, and monobactams. And therefore are classified as β-Lactam antibiotics. β-lactam is a highly efficient and economical broad spectrum that is widely used in prevention and treatment of bacterial disease. Almost all of these antibiotics function by inhibiting bacterial cell wall biosynthesis. However, bacteria often develop resistance to β-lactam antibiotics. Once a bacterial population has developed these resistant subgroups, further treatment with β-lactam antibiotics can result in increasing prevalence and virulence of resistant strains in the population. Recently, the government has controlled the use of β-lactam to prevent any residues in food.
