Poliomyelitis Virus IgG ELISA Kit

Full Name: Poliomyelitis Virus IgG ELISA Kit
Reactivity: Human
Sample Type: Serum, Plasma
Sensitivity: 1.4 U/ml

BACKGROUND

Poliomyelitis (often known as polio or infantile paralysis) is caused through the infection by polivirus (PV), a family member of the genus Enterovirus. These are a group of RNA viruses which tend to colonise within the gastrointestinal tract (more specifically the oropharynx and the intestine). The disease can be prevented by using the polio vaccine but it could require many doses for the vaccine to be effective. The disease is usually diagnosed by finding the virus within the feces or using antibodies against it in the blood, also only in humans it is found to occur naturally.

INTENDED USE

Human poliomyelitis virus IgG ELISA kit is a procedure for measuring in-vitro concentrations of human IgG antibodies against poliomyelitis virus (polio IgG) using samples of plasma or serum. This assay has a minimum analytical sensitivity limit of 1.4 U/ml.

CONTENT

All reagents supplied need to be stored at 2 °C – 8 °C, unopened reagents will retain reactivity until expiration date. Do not use reagents beyond this date.

• Polio antigen coated microtiter strips.
• Negative Control (Calibrator A).
• Cut-Off Standard (Calibrator B).
• Positive Control (Calibrator D).
• Weak Positive Control (Calibrator C).
• Enzyme Conjugate.
• Sample Diluent.
• TMB Substrate.
• Washing Buffer (10x).
• Stop Solution.

SENSITIVITY

The minimum detection sensitivity level of IgG antibodies to poliomyelitis virus (polio IgG) using current poliomyelitis IgG ELISA kit was 1.4 U/ml. The dynamic range for this assay is 1.0 – 150.0 U/ml.
