IGF–I ELISA Kit (Rat/Mouse)


Rat/Mouse IGF-I ELISA kit can be used for measuring quantitative levels of mouse or rat insulin-like growth factor-I (IGFI, IGF-I) using serum and plasma samples. This assay has a minimum sensitivity detection limit of < 0.029 ng/ml.


Insulin-like growth factor I (IGF-I) is also referred to as somatomedin C, it is a sulfaction factor which has a similar molecular structure as insulin and it also possesses non-suppressible insulin-like activity. IGF-I has a molecular weight of 7,649 Da, containing a single chain of 70 amino acids that is held together by three intracellular disulphide bridges. It is mainly produced as an endocrine hormone through the liver and has the ability to target specific tissues in either an autocrine or a paracrine manner. IGF-I is the predominate mediator of growth hormone effects, which are found to be mediated via IGFIR receptor, leading to the activation of the AKT signalling pathway. This can result in the stimulation of cell growth and proliferation, it is a potent inhibitor of programmed cell death.


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.
