Ampicillin (AMP) 10 µg refers to small, filter paper discs containing 10 micrograms of the antibiotic ampicillin, used in microbiology labs for the Kirby-Bauer method (disc diffusion test) to determine if a specific bacteria is sensitive or resistant to ampicillin, guiding clinical treatment for infections like meningitis, pneumonia, or UTIs. These discs help identify effective treatments by measuring zones of bacterial growth inhibition on agar plates, with "AMP 10" printed for easy identification. 

Bacitracin B 10 IU refers to a standard concentration of the antibiotic bacitracin, typically found in small paper discs used in microbiology labs for Antimicrobial Susceptibility Testing (AST), especially the Kirby-Bauer method to check if bacteria like Streptococcus pyogenes are sensitive to it, helping guide treatment decisions. These discs contain 10 International Units (IU) of bacitracin and help determine effective antibiotic regimens for infections. 

In this kit. Combining the method of preparing membrane with high adsorption amount of DNA and selectively adsorbing DNA to achieve the purpose of rapid purification of plasmid DNA. It applies to extract up to 60ug of high purity plasmid DNA from 5-30 ml bacterial culture. It has been used in molecular biology experiments such as sequencing. in vitro transcription and translation. restriction endonuclease digestion and bacterial transformation.

The kit is suitable for extracting high purity total DNA from fresh or frozen animal tissues, cells, blood, bacteria and other samples. DNA fragments with a maximum molecular weight of 50 KB can be purified without the use of toxic solvents such as phenol or chloroform and ethanol precipitation. The optimized buffer system was used to efficiently and specifically bind DNA from the pyrolysis solution to the silica-based centrifugal adsorption column. PCR and other inhibitors of enzymatic reaction could be effectively removed by two-step washing steps. Finally. high purity DNA could be obtained by using low-salt buffer or water elution. The purified DNA can be directly used in enzyme digestion, PCR, Real-Time PCR, library construction, Southern Blot, molecular markers and other downstream experiments.

This kit uses a unique buffer system that combines with traditional isopropanol precipitation to quickly obtain large amounts of high-purity plasmid DNA. The plasmid DNA extracted using this kit can be applied to various routine operations. Including restriction enzyme digestion, PCR, sequencing, ligation, transformation and transfection of a variety of cell experiments.It is recommended to use the amount of bacteria every time: the recommended amount of high-copy plasmid is 100 ml. the yield is generally about 200-1500ug the recommended amount of low-copy plasmid is 200 ml. and the yield is generally about 100-400ug.

When the width of the sample well during electrophoresis is less than 5 mm, a clear band can be obtained by taking 5 μl Marker electrophoresis each time. If the sample hole is widened, the sampler volume of Marker must be increased appropriately.**2. For DNA electrophoresis, the purity of Agarose greatly affects the clarity of DNA bands. Therefore, the best quality Agarose should be used for electrophoresis. The recommended gel concentration is 0.8% to 1%.**3. When performing Agarose electrophoresis, the concentration of Agarose is closely related to the separation performance of DNA fragments. The greater the concentration of Agarose, the better the separation performance of short DNA; conversely, the smaller the concentration of Agarose, the more favorable for the separation of long DNA.*

DNA Marker IV is composed of 7 kinds of DNA fragments with a length of 200 bp to 4,500 bp, dissolved in 1×Loading Buffer, and can be used for direct electrophoresis of 5-10 μl during use, which is very convenient to use
