COX-2 (Cyclooxygenase-2) ELISA Kit (Rat)


Rat COX-2 ELISA kit can be used for detecting quantitative levels of rat cyclooxygenase-2 (COX2, COX-2) in the lysates of tissues or cells. This assay has a minimum sensitivity detection limit of 0.16 ng/ml.


Cyclooxygenase-2 (COX2) is also called prostaglandin G/H synthase 2 (PGHS2), it is an enzyme that is membrane bound that is important in the catalysis of prostanoid synthesis. It is responsible for the forming of prostanoid which can include prostaglandins and thromboxane (for example prostacyclin). Prostaglandins are essential composed of two enzymes, cyclooxygenase-1 (COX-1) and cyclooxygenase-2 (COX-2). The expression of COX-2 is tightly regulated and induced through many inflammatory mediators such as cytokines, growth factors and endotoxin. Functionally, COX2 is a homodimer that is responsible for catalysing two steps during the conversion process of arachadonic acid into prostaglandin H2. It can be inducibly-expressed by many different cell types such as monocytes, endothelium, fibroblasts and vascular smooth muscle cells.

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.
