Chlamydia Pneumoniae IgG ELISA Kit


Human Chlamydia pneumoniae IgG ELISA kit is a procedure intended for in-vitro quantitative detection of human IgG class antibodies to Chlamydia pneumoniae (Chlamydia pneumoniae-IgG) in serum or plasma samples. This assay has a minimum analytical sensitivity limit to a diagn. 90.2%.


Chlamydia pneumoniae is a type of gram negative bacterium which can infect the lungs, the infection is characterised by a gradual onset of the symptoms that is followed by a long incubation period (3-4 weeks). C. pneumoniae can also infect many other human cells such as lymphocytes, macrophages, monocytes, smooth muscle, epithelial and endothelial cells. Also, pneumonia which has been caused by C. pneumoniae is usually regarded as atypical, since antibiotics which are used to treat pneumonia that has been caused by other types of bacteria do not work against Chlamydia pneumoniae infections. It has also be called an energy parasite because it requires a host cell for obtaining ATP and other high-energy intermediates. There is evidence to indicate that if chlamydial infections are untreated then this could result in chronic salpingitis, which could lead to infertility or even ectopic pregnancy. This most widely used procedures for detecting this pathogen or infection is by microscopy, PCR, antigen and antibody detection using ELISA methods.


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.

The minimum detection sensitivity level of IgG class antibodies to Chlamydia pneumoniae using current human Chlamydia pneumoniae-IgG ELISA kit was to a diagn. 90.2%. The dynamic range for this assay is to a specific cut-off point.

Your secretory IgA ELISA gave good results and I was also really impressed with how quickly we received it.

It is refreshing to know that you have a technical team that is very knowledgeable. I have already recommended your company to other researchers in our department.

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.

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.

You are my first point of contact when I am looking to purchase ELISA. You have such an easy and simple system, yet it is very effective.
