Gold Label Cassette

Colloidal gold immunochromatography technology is widely used in biomedical fields, and its application in the detection of animal derived foods has only recently developed. Domestic research mainly focuses on diagnosis, and research on its application in the detection of animal derived foods has just begun.

For component analysis that does not require quantitative detection but requires detection results, colloidal gold immunochromatography technology is particularly suitable.

The IgG content of bovine colostrum has become a good indicator for evaluating the biological activity of bovine colostrum and its products. Li Zhongqiu et al. used gold label cassettes to label the standard bovine IgG as a competitive antigen.

Wrap it on the binding pad of the test strip and solid-phase the self-made rabbit anti bovine IgG antibody in the detection area of the nitrocellulose membrane. The level of IgG in milk samples is reflected by the competition between IgG in milk samples and colloidal gold labeled standard bovine IgG for binding to IgG antibody binding sites. This operation requires a short time, can perform simple semi quantitative analysis, and has good specificity& Nbsp
