Cats who develop FIP have an immune defect or deficiency that causes the white blood cells to replicate, rather than fight, the virus. Essentially, the cats immune system is spreading the virus throughout the cat's body rather than trying to eliminate it. Cats who have no immune response develop wet FIP, while cats who have a partial immune response develop dry FIP. The nucleoside analog GS-441524 is a molecular precursor to a pharmacologically active nucleoside triphosphate molecule. These analogs act as an alternative substrate and RNA-chain terminator of viral RNA dependent RNA polymerase. In layman's terms, GS441 interjects itself into the chain reaction and stops the replication of the virus.

Raschig rings is also called cylindrical ring. It was invented by F. Rasching in 1914. As one of the earliest tower packing in the Chemical Industry, Raschig Ring is also the most widely used column packing worldwide. Pall ring was exactly developed from raschig super ring. Ceramic Raschig Ring Ceramic raschig ring column has excellent acid resistance and heat resistance. It can resist to corrosion of various inorganic acids, organic acids and organic solvents except for hydrofluoric acid. Metal Raschig Ring Metal Raschig Ring (MCR) is proved to be a kind of good tower packing a wide range of mass transfer applications. It provides one of those largest surface areas among tower packing options. Metal Super Raschig Ring NAIKE Metal random packing is made of materials like carbon steel, stainless steel or Aluminum alloy, etc. The product has features such as thin wall, heat resistant, high void ratio, high capacity. Plastic Raschig Ring NAIKE Plastic Raschig rings are pieces of the tube (approximately equal in length and diameter) used in large numbers as a packed bed within columns for Distillations and other chemical engineering processes.

Homocysteine (Hcy) is a sulfur-containing amino acid metabolized by methionine, 80% of Hcy conjugated by disulfide and protein in the blood, only a small part of free homocysteine to participate in the cycle. Hcy levels are closely related to cardiovascular disease, are an important risk factor for cardiovascular disease. Increased blood Hcy to cause arterial injury by stimulated blood vessel wall, to formed inflammation and wall plaques, and eventually blocked the flow of cardiac blood. Deficient nutrition for Vitamin B followed with moderate or mild Hcy increased, also increases the risk of heart disease. Hipro's homocysteine reagent blood test kit can be used to determine the content of homocysteine (HCY) in the human serum and plasma in vitro quantitative determination. Testing Principle of Homocysteine (HCY) Lab Blood Test Hipro's homocysteine levels test uses the enzymes conversion method to quantify the total concentration of homocysteine in the blood, no antibody reagents need to add in. Reducing the oxidation state of homocysteine by dithiothreitol (DTT) first, then decomposing homocysteine by the recombinant enzyme. The product formed by reaction and the appropriate coloring agent will be formed to the measurable fluorescent compounds. This fluorescent material can fluoresce by a specific wavelength of 670nm at 700nm. Basic Parameters of Homocysteine (HCY) Lab Blood Test Specimen: serum. Test time: 420 seconds.

The d dimer reagent produced by Hipro are used to determine the content of D- Dimer (D-Dimer) in human blood, and a specific reagent for the specific protein analyzer applies only to the clinical in vitro assisted diagnosis. D-Dimer is one of fibrin degradation product (FDP) decomposed by cross-linked fibrin and plasmin, due to the role of coagulation factor Ⅹ Ⅲ, in the blood coagulation - fibrinolysis system. D- Dimer in blood increased has proved that the body has thrombosis. The high values also shown in obstetric disorders, vascular disease, disseminated intravascular coagulation syndrome (DIC: Disseminated Intravascular Coagulation Syndrome) etc. Testing Principle of D-Dimer Test The D-Dimer units conjugated anti-human D-Dimer antibodies in the latex surface. D-Dimer in the sample and the antibody become immune complexes by Latex condensation reaction. The immune complexes will produce the phenomenon of light scattering, which is proportional to the intensity of scattered light and samples of D-Dimer levels. Using a specific protein analyzer to measure the intensity of scattered light, the concentration of D-Dimer is determined by comparing the turbidity of samples to the standard concentration. Basic Parameters of D-Dimer Test Specimen: plasma. Test time: 180 seconds. Packing: 25 Tests/ Kit. Box Size: 17*10*8cm. Storage: 2-8℃. Shelf life: 1 year.
