High-performance liquid chromatography (HPLC) columns are used for the analysis or preparation of separated compounds from complex mixtures. The pressurized liquid solvent containing the sample mixture passes through a column filled with a solid adsorbent material. Since each component in the sample interacts with the adsorbent material slightly differently, the components with different flow rates are separated as they flow out of the column. According to separation mechanism, common HPLC colum...

Laboratory equipment is a general term for the various instruments, containers and other tools needed for operation, synthesis, and analysis in various laboratories. The equipment helps researchers to observe, test, experiment or analyze data to confirm the authenticity or rationality of scientific hypotheses. According to the scope of application, laboratory equipment can be divided into general equipment and specialized equipment.General laboratory equipment includes freezers, incubators, shak...

ethylation-Based Biological Age and Cancer RiskChanges in DNA methylation levels with age, and it has been widely studied as a well-known biomarker of aging. A number of DNA methylation age clocks have appeared and been used, and when the age predicted by the methylation clock is greater than the actual age, it is considered to have "age acceleration", which is also called the biological measure of aging.Research suggests a correlation between aging and cancer as well. Predicted ages obtained by...

Matexcel, a quality provider of products and services in material sciences, recently released Egg Shell Hydroxyapatite that can be integrated into biomedical and environmental projects. Egg Shell Hydroxyapatite is a type of hydroxyapatite that is derived from the shells of eggs. Hydroxyapatite is a naturally occurring form of calcium and phosphate, which is a major component of bone and hard tissues. When egg shells, which are rich in calcium, are processed correctly, they can create this valuab...

The ability to overexpress genes in microorganisms has revolutionized the field of synthetic biology. Gene overexpression involves the production of large quantities of target proteins by increasing the transcription and translation of the gene of interest. This technique has been applied in the engineering of microorganisms to produce a wide range of products, including biofuels, chemicals, and biopharmaceuticals. There are several strategies for gene overexpression in strain engineering. One c...

Strong base anion (SBA) exchange resin is one type of ion exchange resins containing quaternary ammonium groups on the microsphere surfaces. The SBA resin shows an excellent physical and chemical stability, which is capable to exchange the different anion under a wide range of pH value. SBA resins are ideal for removing certain anionic contaminants and can be regenerated with salt.SBA resins are usually divided into two classes according to their functional groups. Type I SBA resins are aminated...

Silica-based vectors are attractive as gene transfer vehicles due to their high stability, safety, and ease of structural and surface modification. A variety of silica-based vectors for gene delivery have been reported, including silica nanotubes (SNT), silica sheets, and silica NPs (solid (non-porous) silica NPs and porous silica NPs). Among these, silica NPs have been extensively investigated by researchers as carriers with many useful and attractive properties.Several reports have been publis...

Bioink is a solution of a biomaterial or a mixture of several biomaterials in the hydrogel form, usually encapsulating living cells, and/or bioactive molecules. For bioprinting, bioinks are essential components, and are cross-linked or stabilized during or immediately after the bioprinting to create the final shapes of the intended tissue constructs.The selection of appropriate bioink depends on the specific application and the type of cells as well as the bioprinter to be used. An ideal bioink ...
