High Sensitive C-Reactive Protein (hs-CRP) ELISA Kit


Human hs-CRP ELISA kit is a method for analysing in vitro quantitative high sensitive concentrations c-reactive protein (hs-CRP) in human serum and plasma. This assay has a minimum detection limit of < 0.02 ng/ml.


C-reactive protein (CRP) is produced exclusively in the liver and it is interleukin-6 (IL-6) which is the chief mediator for the synthesis of CRP by hepatocytes. It has a total approx. molecular mass of 120.000 Daltons and is made up of a symmetrical pentamer structure. Human CRP is essentially a kind of non-immunoglobulin serum substance which is also a heat labile beta-globulin. It is found to be present in the active stages of many inflammatory disorders such as rheumatoid arthritis, psoriatric arthropathy, Crohn’s disease, systemic lupus erythematosus, Reiter’s syndrome, polyarteritis, ankylosing spondylitis and ulcerative colitis.

The CRP-level can increases dramatically after microbial infections and this property has been particularly helpful for the diagnosis and monitoring a large number of bacterial septicemia in neonates and in many other immune-compromised patients. The concentrations of c-reactive protein begin to rise within 6 hours of an acute inflammatory challenge. Also, many injuries that are responsible for causing necrosis and tissue breakdown are also found to elevate serum CRP levels, examples of these are observed in major surgery, myocardial infarction and thermal burns. A number of widespread malignant diseases including Hodgkin’s disease, lymphosarcoma, non-Hodgkin’s lymphoma and many carcinomas (lung, pancreas, stomach, breast, colon and prostate) can also give rise to high levels of CRP which result from tissue damage that is caused by invading tumour cells.


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.
