Evergreen Lactoperoxidase Activity Assay Kit

Lactoperoxidase (LPO) is a naturally occurring enzyme in milk. It is the most important peroxidase capable of oxidizing the thiocyanate ion (SCN-) in the presence of hydrogen peroxide (H2O 2). In milk, the main function of LPO is to catalyze the oxidation of molecules to produce products with a wide range of antibacterial activity. LPO plays an important role in the immune system of dairy cows. In the dairy industry, LPO is also an important intrinsic indicator for monitoring and assessing the severity of heat treatment, as it is one of the most thermostable enzymes in milk, which cannot be inactivated by an ordinary pasteurization process (63°C for 30 minutes or 72°C for 15 seconds), partially inactivated by an instantaneous pasteurization process at 74°C, and completely inactivated by UHT or ultra-high temperature pasteurization. Measuring LPO activity has been widely used to assess the extent and efficiency of mild heat treatment.

Evergreen Lactoferrin Assay Kit

Lactoferrin appears in animal milk, especially colostrum. The concentration of lactoferrin in human milk is about 1.0-3.2 mg/ml, which is 10 times that of cow milk (the content of cow milk is 0.02-0.35 mg/ml), accounting for 20% of the total protein of ordinary breast milk. During lactation, the content of lactoferrin changes with the lactation time. For example, the lactoferrin human colostrum can reach 6-14 mg/ml, the normal milk period is reduced to 1 mg/ml. Lactoferrin and its protein degradation product-lactoferricin peptide have a wide range of biological activities

Evergreen Bovine β-Lactoglobulin ELISA Kit

Beta-lactoglobulin (bLG) is the main whey protein in cow's milk (3g/l) and is also present in the milk of most other mammals, except humans. Bovine β-lactoglobulin accounts for about 50% of bovine whey protein. Studies have shown that bLG binds to fat-soluble vitamins, fatty acids, and other hydrophobic compounds, and is therefore bioavailable. bLG is also an excellent source of essential and branched-chain amino acids

Evergreen bovine α-lactalbumin ELISA Kit

Alpha-lactalbumin is a protein found in the milk of most mammals and plays a major role in antibody defense mechanisms. Human alpha-lactalbumin (bLA) is the major protein in human whey. The amount of bovine alpha-lactalbumin occupies the second place in bovine whey, accounting for 20-25% of bovine whey protein. 74% of the amino acid sequence in bLA is homologous to human α-lactalbumin, so it is an important raw material for some foods.

Evergreen Bovine Ig G ELISA Kit

IgG is the most important immunoglobulin in livestock and human serum and plays a major role in antibody defense mechanisms. The content of bovine IgG in serum is 17-27 mg/ml, but it will change with season. IgG is also the predominant immunoglobulin in the colostrum of livestock, including cattle. The content of IgG in bovine colostrum is 34-80 mg/ml, while the content of IgG in cow's milk is 0.5-7.5 mg/ml.

Evergreen Bovine Ig M ELISA Kit

Bovine IgM(bIgM) is found in serum, colostrum and cow milk. IgM plays an important role in the primary immune response, complement fixation, and is a serum agglutinating antibody. Most IgM is obtained from colostrum during the first 16 hours of life, providing protection for cattle. After 30 to 80 days, the cattle begin to self-produce sufficient quantities of IgM. EvergreenTREATM bovine IgM kit can quantitatively detect natural active bovine IgM in milk and milk powder, which is rapid, sensitive and reliable. The kit contains all the reagents required for the ELISA reaction. The kit is sufficient for 96 tests (including standards). detection principle of this kit is the use of double anti sandwich enzyme linked immunosorbent assay method for detection. The anti-bovine bIgM antibody is coated in the microplate. After addition of the bovine bIgM standard or sample, the free bovine bIgM binds to the pre-coated anti-bovine bIgM antibody on the microplate and unbound proteins and molecules are removed in a first washing step. Subsequently, horseradish peroxidase-labeled bovine bIgM antibody is added, the captured bovine bIgM is then combined with the enzyme-labeled bovine bIgM antibody, and the unbound horseradish peroxidase label is washed. With TMB substrate color, after adding acidic stop liquid color from blue to yellow, with a microplate reader at 450nm wavelength to determine the absorbance value, absorbance value and the content of bovine bIgM in the sample is proportional. The test results can be obtained by comparing the absorbance value of the sample with the absorbance value of the standard provided by the kit. Specificity The ability to specifically detect bovine IgM, with no specific reaction with other bovine immunoglobulins or other bovine serum proteins.

Evergreen Bovine Ig A ELISA Kit

IgA is the major immunoglobulin in human colostrum and cow's milk. However, IgA is predominant in most domestic animals including cattle, and IgA is a minor component. IgA is also present in serum, where it primarily plays a role in the inflammatory response. The range of IgA(bIgA) in bovine colostrum is 1.8-14.5 mg/mL; in serum, the range is 0.06-1.0 mg/mL.

Zhongjian Baotai L-Carnitine Test Kit

Zhongjian Baotai Lactulose Test Kit

Lactulose is a disaccharide composed of D-galactose and D-fructose, which is one of the important products of dairy thermal processing. The lactulose content in raw milk is very low, and after heat treatment, such as lactose in milk isomerization to form lactulose (also known as isomerized lactose). The greater the intensity of the heat treatment, the greater the amount of lactulose produced. According to this characteristic, it is used as one of the important indexes in the identification standard of reconstituted milk in NY/T939-2016 pasteurized milk and UHT sterilized milk.
