Penicillinase is an enzyme that acts on the β-lactam ring of penicillin to convert penicillin into penicillic acid, which has no antibacterial activity. A variety of penicillin-resistant bacteria can produce this enzyme, such as the penicillin-resistant strains of Staphylococcusaureus and the penicillin-resistant strains of Bacillus cereus. This enzyme is a medical enzyme suitable for the treatment of allergic reactions to penicillin in general, and can also be used as an adjunctive treatment for patients with anaphylaxis or severe penicillin allergic reactions. Bacillus cereus can be used as a production strain of this enzyme.

In short, different diseased PBMCs were used for a wide variety of immunology-based applications, including in vitro immunoassays, population characterization, sequencing studies, and biologic testing as above. However, in the application process, attention should be paid to the quality stability, ethical issues of traceability, whether the cells are fresh, the selection of appropriate cells for different studies, etc.
Brief Introduction to PBMCs Peripheral Blood Mononuclear Cells (PBMC), also called Human Mononuclear Cells from Peripheral Blood (HMNC-PB), are cells with a single, round nucleus that are collected from peripheral or circulating blood. These blood cells are a key component in the immune system to fight infections and disease, adapting to invaders. PBMCs resp…
The functions of MSCs mainly include differentiation capacity, immune regulation and antimicrobial properties. Differentiation capacity indicates the identity of MSCs stem cells and makes it become the basis for maintaining organ and tissue survival [16]. MSCs are also involved in immunomodulatory processes. MSCs can affect a variety of innate and specific immune cells and can produce a variety of immune factors. And the antibacterial ability of MSCs mainly comes from their ability to produce a variety of antibacterial peptides, which enables MSCs to have broad-spectrum antibacterial activity.
Introduction What are Stem Cells? Stem cells refer to undifferentiated or partially differentiated cells in multicellular organisms. Stem cells can replicate indefinitely and differentiate into differ…

Benefits of forced degradation test The degradation pathway of the drug is closely related to the molecular structure of the drug. The ester group or amide bond in the molecular structure may be hydrolyzed under acid-base catalysis conditions. Provide support for drug safety. When toxicologically relevant impurities are not readily available, toxicological evaluation of samples degraded to a certain extent can provide a supportive basis for drug safety and impurity limit determination. It is helpful for metabolite research. Some degradation products are also metabolites, and the m…
Long non-coding RNAs (lncRNAs) are a class of RNAs that do not code for proteins and are typically greater than 200 nucleotides in length. Studies have shown that lncRNAs are quite complex in function and play an important role in various biological processes such as development, differentiation, proliferation, metastasis, apoptosis, stem cell pluripotency, and DNA damage. Therefore, those non-coding fragments in human genes are also vital and not the so-called "transcriptional noise".

The biological function of restriction enzymes is derived from the defense of foreign DNA from invading cells. The restriction-modification system of bacteria makes the DNA bases of bacteria to be methylated and modified, so that they are not recognized and cut by their own restriction enzymes.
The biological function of restriction enzymes is derived from the defense of foreign DNA from invading cells. The restriction-modification system of bacteria makes the DNA bases of bacteria to be methylated and modified, so that they are not recognized and cut by their own restriction enzymes.   The development of restriction endonucleases In the early 1960s, Werner Arber came up with the idea that there was an enzyme that would cut the DNA of a virus, thereby limiting the virus' proliferation.…
Mitochondria are important organelles of eukaryotic cells and play a key role in the regulation of cellular energy metabolism, biosynthesis and cell death (including apoptosis and programmed cell necrosis). In addition, mitochondria are involved in important physiological processes such as tricarboxylic acid cycle, fatty acid and amino acid oxidation, and regulation of calcium ion homeostasis. Since mitochondria play an important role in the maintenance of homeostasis, their abnormal function is associated with many human diseases, such as neurodegenerative diseases, cancer, heart disease and diabetes.
