How to choose a film

In the late 1950s, China introduced polyvinyl chloride film for rice breeding. At the beginning of the 60's, a polyvinyl chloride film was developed and its application was broadened to vegetable production. At the end of the 1970s, the polyethylene anti-aging film (resin film, long-life film) was successfully developed. In the late 1980s, a better performance polyethylene anti-aging film was developed. At the same time, due to the development of energy-saving solar greenhouses, polyvinyl chloride aging-preventing films with better heat-insulating and drip-proof properties have also begun to be widely applied. In the mid-1990s, it also developed an ethylene-vinyl acetate weatherproof functional film that combines the advantages of a polyethylene weatherable functional film and a polyvinyl chloride weatherproof functional film. The current application of the film on the production, according to the performance of the difference is divided into ordinary film, weathering film, weathering function film (anti-drop, anti-fog, insulation, light, etc.), weathering function film according to the different functions are divided into anti-drip Aging film, anti-aging anti-aging film, anti-aging anti-aging film, anti-aging anti-aging anti-aging and the above-mentioned anti-fogging functional film type. According to the different raw materials used in production, it is divided into: polyethylene tent film, polyvinyl chloride film and ethylene vinyl acetate film (The characteristics of these three films are compared in the table). Faced with such a large number of films, the selection of products with excellent performance, economy, and roads, and rational use, can increase production and increase income, reduce costs, and improve application results.

PCR Reagents

Real time PCR Kit for Monkeypox Virus is used for in vitro qualitative nucleic acid detection of Monkeypox Virus in Human serum, lesion exudate samples and scab specimens. Primer sets and FAM labeled probes are designed for specific detection of Monkeypox Virus, Human RNase P gene extracted concurrently with the test sample provides an internal control to validate nucleic extraction procedure and reagent integrity. Probe targeting human RNase P gene is labeled with VIC.


Intended Use
The test is intended for in vitro qualitative detection of monkeypox virus
(MPXV) antigen in human oropharyngeal swab, whole blood or skin lesion
materials, including lesion exudate, lesion roofs, lesion crusts.
The test is used for monkeypox virus antigen test of monkeypox suspected
populations. Positive result of the antigen test can be used for early triage and
rapid management of suspected populations, but it cannot be used as
diagnosis basis of monkeypox infection. Negative results do not rule out
monkeypox infection and should not be used as the sole basis for treatment or
patient management decisions. Further nucleic acid detection should be
carried out for suspected population whose antigen test result is positive or
negative.
The test is only for professional use, not suitable for family test. The test result
is only for clinical reference and it is recommended to conduct comprehensive
analysis of the disease condition in combination with clinical manifestations of
patients and other laboratory tests.
Test Principle
According to the gold immunochromatographic test principle, the
nitrocellulose membrane is coated with MPXV mAb 2 and goat anti-mouse IgG
antibody, the gold conjugate pad is labeled with MPXV mAb 1. When the
antigen is contained in the sample, the antigen binds with the corresponding
gold labeled monoclonal antibody to form a compound, moving forward under
the chromatography, then combines with the coated antibody in the test line
to form Au-MPXV mAb 1-antigen-MPXV mAb 2 complex to condense into a red
band (Test line, T), indicating a positive result. When the sample does not
contain antigen, complex cannot be formed in the test line, and no red band
appears, indicating a negative result.
No matter whether the sample contains antigen or not, the gold labeled
monoclonal antibody will combine with the coated goat anti-mouse IgG
antibody at the control line to form a Au-MPXV mAb 1-goat anti-mouse IgG
antibody complex and condense into a red band (Control line,C)
