Full Name: Measles IgG ELISA Kit
Sample Type: Serum, Plasma
Sensitivity: 1.35 U/ml
Measles (also called rubeola), is an extremely contagious viral disease which can be transmitted by respiratory secretions. The measles virus is a negative sense, single stranded enveloped RNA virus that belongs to the Morbillivrus (Paramyxovirdae family).
Measles virus can infect cells in the lungs and those that are at the back of the throat, causing symptoms such as sore throat, dry cough, a runny nose, tiny white spots inside the mouth, a high fever, red eyes and a characteristic rash. Two of the most common methods which are used for detecting this infection are: antibody testing (IgG and IgM) and viral isolation detection (RT-PCR).
Human measles IgG ELISA kit is intended for analysing in-vitro levels of human IgG antibodies against measles virus (measles-IgG) using plasma or serum. This assay has a minimum analytical sensitivity limit of 1.35 U/ml.
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.
