Application

Sodium phosphate dibasic solution has been used:
  • to supplement Dulbecco′s Modified Eagle Medium (DMEM) in calcifying medium to induce the calcification of vascular smooth muscle cells (VSMCs)
  • to prepare a stock solution of CaCl2 and MgCl2 to synthesize calcium phosphate (CPB) and magnesium phosphate bions (MPBs) respectively
  • to supplement 2xYT agar plates to culture BL21 DE3 star cells and BL21dLac Gold cells

Sodium phosphate dibasic solution may be used in the preparation of a wide variety of phosphate based biological buffers for use in cell and molecular biology application.

Calciprotein particles (CPPs), which increasingly arise in the circulation during the disorders of mineral homeostasis, represent a double-edged sword protecting the human organism from extraskeletal calcification but potentially causing endothelial dysfunction. Existing models, however, failed to demonstrate the detrimental action

Loss of gamma-sarcoglycan (γ-SG) induces muscle degeneration and signaling defects in response to mechanical load, and its absence is common to both Duchenne and limb girdle muscular dystrophies. Growing evidence suggests that aberrant signaling contributes to the disease pathology; however

The rate of obesity among men of reproductive age has tripled in the last three decades. Previously, we demonstrated that paternal obesity resulted in impaired preimplantation developmental kinetics, compromised post-compaction metabolism and decreased blastocyst cell number when embryos were generated

Interactions between a host and a bacterial pathogen are mediated by cross-talk between molecules present on, or secreted by, pathogens and host binding-molecules. Identifying proteins involved at this interface would provide substantial insights into this interaction. Although numerous studies have

The aim of this study was the development of poly(D,L-lactide-co-glycolide) (PLGA) microspheres with controlled porosity, to obtain microspheres that afford continuous release of a macromolecular model compound (blue dextran). PLGA microspheres with a size of around 40 μm and narrow size

Protokoly

Enzymatic Assay of Hyaluronidase (3.2.1.35)

To measure hyaluronidase activity, a turbidimetric determination assay is used at 600 nm. One unit of hyaluronidase activity will cause a change in absorbance of 0.330 per minute at pH 5.35 at 37 °C.

Enzymatic Assay of Alcohol Dehydrogenase (EC 1.1.1.1)

To measure alcohol dehydrogenase activity, this assay uses β-nicotinamide adenine dinucleotide phosphate and a continuous spectrophotometric rate determination at 340 nm.
