Chlamydia Trachomatis IgG ELISA Kit


Human Chlamydia trachomatis IgG ELISA kit is designed for analysing in-vitro quantitative concentrations of human IgG antibodies against Chlamydia trachomatis (Chlamydia trachomatis-IgG) in serum and plasma samples. This assay has a minimum analytical sensitivity limit to a diagn. >95.0%.


Chlamydia trachomatis has been described as one of the most common bacterial sexually transmitted infections worldwide and also women are regarded as carrying the major burden of the disease. Chlamydial infection has been found to result in casing a cause disease in a number of different organ systems, which includes the genitourinary tract. C. trachomatis is a strong immunogen, which can stimulate both cell mediated and humoral immune responses. The general outcome of the chlamydial infection is largely dependent on the overall balance and interaction of cytokines that have been secreted by the activated lymphocytes. IFN-γ is regarded as an important factor which is vital in the host defence against Chlamydia, while on the other hand the susceptibility to the disease has been associated with enhanced expression of IL-10. The means that the changes to the immune system or even any disturbances which have been induced by C. trachomatis could either favour its own survival in the infected host or it could induce persistent infections.


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.

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.
