The most obvious chemical activity of VC is that reduce Fe3+ to Fe2+, then promote iron absorption in the intestine, promote the storage and utilization of iron. Fe3+ react immediately with reducing ascorbic acid to form Fe2+. then Fe2+ react with phenanthroline and the color developing reaction occurs. The content of vitamin C in sample can be determined. Measure the OD value and calculate the VC content indirectly.

Iron is one of the metal elements in organism and has important physiological functions. Ferrous ion is a key element in heme and hemoglobin and plays an important role in many biochemical reactions. Ferrous ions (Fe2+) in samples can bind with probe to form complexes, which has a maximum absorption peak at 593 nm. The concentration of ferrous ions can be calculated by measuring the OD value at 593 nm indirectly.

Free fatty acids produce acyl coenzyme A in the presence of acyl synthase, which produces hydrogen peroxide in the presence of acyl oxidase. In the presence of the enzyme and probe, hydrogen peroxide react to produce the fluorescence substrate. The fluorescence intensity at the excitation wavelength of 535 nm and emission wavelength of 590 nm is directly proportional to the concentration of free fatty acids.

In vitro cell culture, in order to preserve the biological activity of cells for a long time, the cells must be cryopreserved, and resuscitated when necessary. At present, the most commonly used method for cell cryopreservation is liquid nitrogen method. In the process, add an appropriate amount of protective agent to slowly cool the cells to the specified temperature range, so as to achieve the purpose of protecting the cells. The Serum-free Cell Freezing Medium is a special cryopreservation product developed by Pricella for hundreds of types of cells by continuously optimizing experimental conditions for cell cryopreservation and resuscitation in the long-term cell research. The product adds cell sedimentation stabilizer, which can delay the sedimentation rate of cells in the process of cryopreservation, prevent cells from squeezing each other and affect the effect of cell cryopreservation. In addition, a variety of cryoprotectants, such as cell membrane protectors, permeable intracellular membrane protectors, and non-permeable cell protectors, are added. These components combine with water molecules in the solution to hydrate and weaken the crystallization process of water, increasing the viscosity of the solution and reducing the formation of ice crystals, which can greatly reduce the damage of ice crystals to cells during cryopreservation, and effectively improve the survival rate of cell after resuscitation. The product formula is clear, does not contain serum or animal derived protein, which can reduce comtamination risk from bacteria, viruses and mycoplasma, and ensure the safety of frozen cells. It is not only suitable for conventional cell lines, primary cells, but also for serum-free culture cells and protein-expressing cells. Compared with traditional cryopreservation media, there is no need for tedious and time-consuming gradient freezing steps, and no need for expensive program cooling equipment. Cells can be directly resuspended and placed at -80℃, and transferred to liquid nitrogen the next day to complete the entire process, saving a lot of time and energy.

DMEM (Dulbecco's Modified Eagle Medium) was developed on the basis of MEM medium. Compared with MEM medium, the content of amino acid increased by 2 times, the content of vitamin increased by 4 times, and the content of non-essential amino acid, trace iron ion and sodium pyruvate were increased by 4 times. The glucose content of DMEM medium was originally designed as 1000 mg/L (low Glucose type), and then developed into 4500 mg/L (high Glucose type), which has been widely used in cell culture. DMEM (High glucose) was widely used in fast growth, low adhesion cells, hybridoma myeloma cells, clone cells, DNA transfected transformation cells, various primary virus host cells, single cell culture and vaccine production. DMEM (High glucose) contains many kinds of amino acids, vitamins, inorganic salts and other ingredients for cell culture, but does not contain protein, lipids or any growth factors, so the product should be used with serum or serum-free additives.
