Mycoplasma Pneumoniae IgM ELISA Kit

INTENDED USE

Human Mycoplasma pneumoniae IgM ELISA kit can be used for analysing in-vitro quantitative levels of human IgM antibodies to Mycoplasma pneumoniae (Mycoplasma-IgM) using samples of plasma or serum. This assay has a minimum analytical sensitivity limit of 1.22 U/ml.

BACKGROUND

Mycoplasma pneumoniae belong to a class of Mollicutes and are able to form atypical bacterial pneumonia which is related to cold agglutinin disease. Mycoplasmas are essentially the smallest self-replicating organisms which contain no cell wall or periplasmic space, have limited metabolic activity and conatin a reduced genome. M. pneumoniae infections are commonly found to cause acute respiratory infections in either children or adults. The cells are typically composed of elongated shapes that are between 100-200 nm in width and 1000-2000 nm in length. Early diagnosis is difficult since there are only a limited number of unusual symptoms. As Mycoplasma pneumoniae progresses then imaging and many other laboratory tests can be used detect it.

MYCOPLASMA PNEUMONIAE IGM ELISA KIT CONTENT

  • Weak Positive Control (Calibrator C).

SENSITIVITY

The minimum detection sensitivity level of IgM antibodies to Mycoplasma pneumoniae using current human Mycoplasma-IgM ELISA kit was 1.22 U/ml. The dynamic range for this assay is 1.0 – 125.0 U/ml.

I am a first time user and found that your instruction manual was very easy to follow. The insulin ELISA assay performed well and I was happy with the results that were generated.

J. Thomas
Senior Technician / Addenbrooke’s Hospital

I carried out a pilot study comparing the performance of many ELISA assay's from different suppliers and found your kits to be one of the better performers. We observed good linearity and tight replicates.
