2024-12-27An innovative tool for monitoring lipid peroxidation levels in living organisms using a lipid peroxidation sensor.Lipid peroxidation sensors have become essential tools for monitoring lipid peroxidation levels. These sensors, equipped with specific chemical or biorecognition elements, can detect lipid peroxidation products—such as lipid peroxides, aldehydes, and ketones—with high sensitivity and specificity.MORE -
2024-12-26What should you do if fungal contamination occurs in cell culture? (How can fungal contamination be prevented?)Fungal contamination is also one of the most common types of contamination in cell culture. Typically, fungal contamination has a more pronounced effect on the surrounding local cells, while cells elsewhere continue to grow normally. Moreover, because fungi reproduce via spores, once contamination occurs, it can easily spread.MORE -
2024-12-26The effects of exosome-depleted fetal bovine serum (the price of serum without exosomes)Fetal bovine serum is an indispensable component of complete cell culture media, as it provides essential nutrients and growth factors that support cell proliferation. However, conventional fetal bovine serum contains a high concentration of bovine‑derived exosomes, which can interfere with studies of exosome secretion by tissues or cells cultured in vitro, thereby compromising the validity of experimental results.MORE -
2024-12-23The ROS Reactive Oxygen Species Assay Kit: a powerful tool for detecting cellular oxidative stress.The ROS reactive oxygen species assay kit, an important biochemical detection tool, is widely used in biology, medicine, environmental science, and other fields. It is primarily employed to measure the levels of reactive oxygen species (ROS) in cells, tissues, or biological fluids, enabling researchers to assess the impact of oxidative stress on cellular and tissue functions and to elucidate the relationships between ROS and the onset and progression of diseases.MORE -
2024-12-20Practical Lab Tips: Techniques for Protein Quantification Using the BCA AssayThe BCA method is an improved version of the Lowry method. Compared with the Lowry method, the BCA method is simpler and more convenient to perform; its reagents and the resulting colored complexes exhibit greater stability, are virtually unaffected by interfering substances, and offer higher sensitivity.MORE -
2024-12-17Instructions for Use of the Black-Glue Worm Removal KitDuring cell culture, contamination by black mold is a common and challenging issue. These minute contaminants appear as small black spots under the microscope—sometimes punctate, sometimes in tiny flakes—and exhibit a characteristic motion of vibrating in place (reminiscent of Brownian motion), severely impacting cell growth and experimental outcomes. To effectively eliminate these contaminants, researchers have developed a black mold removal kit, providing robust support for cell culture workflows.MORE -
2024-12-13What is the difference between PVDF membranes with 0.22 µm and 0.45 µm pore sizes? (Precautions for PVDF membranes)PVDF membranes (polyvinylidene fluoride membranes) are widely used in Western blotting for protein transfer; however, as a hydrophobic polymer, they must be pre‑treated and activated prior to use to enhance their compatibility with aqueous buffers. PVDF membranes are available in various pore sizes, which influence their performance and suitability for filtration and separation applications.MORE -
2024-12-09The Black-Glue Worm Removal Kit: A Cleaning Guardian in Cell CultureDuring cell culture, contamination by Acanthamoeba is a common and challenging issue. These microscopic organisms not only impede normal cell growth but can also introduce biases into experimental results. To address this problem effectively, an Acanthamoeba removal kit has been developed, serving as a reliable safeguard for clean cell cultures.MORE -
2024-12-03What are the five commonly used types of cell lysis buffers, and what are their applications?Cell lysis refers to the process of disrupting cellular structures to release their internal components. The goal is to isolate intracellular biomolecules, such as proteins and nucleic acids, for subsequent analysis and research. Lysis buffers are widely used in biomedicine, molecular biology, pharmacology, microbiology, biochemical analysis, and other fields.MORE -
2024-11-29Which is better, CS10 cryopreservation solution or Li Ji cell cryopreservation solution? How should you choose?Cell cryopreservation solution serves as the liquid environment during cell freezing, providing nutrients and protective effects. It lowers the freezing point, increases the permeability of the cell membrane to water, and facilitates the efflux of intracellular water prior to freezing, thereby preventing or minimizing ice‑crystal–induced damage. This allows cells to temporarily enter a quiescent state while preserving their cellular characteristics, enabling direct resuscitation when needed to restore cellular viability.MORE
