Diphtheria Toxoid IgG ELISA Kit
Full Name: Diphtheria Toxoid IgG ELISA Kit
Reactivity: Human
Sample Type: Serum, Plasma
Sensitivity: 0.004 IU/ml
BACKGROUND
Diphtheria toxoid bacteria has the capability to generate a potent toxin which leads to irritation of the throat, nose and skin for individuals who come in contact with it. Left untreated, the exotoxin can be deadly as it causes intense tissue and organ damage due to the severe inflammation.
There are vaccines to protect us against diphtheria, with these vaccines and proper preventive measures, this deadly disease can be stopped from spreading.
INTENDED USE
Human diphtheria toxin IgG ELISA kit is designed for detecting in-vitro levels of human IgG antibodies against diphtheria toxin (diphtheria toxoid IgG) using samples of plasma and serum. This assay has a minimum analytical sensitivity limit of 0.004 IU/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.
