Prolactin (PRL) ELISA Kit (Canine)


Canine prolactin ELISA kit is a procedure for measuring quantitative amounts of prolactin (PRL) using canine (dog) serum samples. This assay has a minimum sensitivity detection limit of 0.4 ng/ml.


Canine prolactin (cPRL) is a single polypeptide chain which is approx. 22,000 in molecular mass, there are significant differences in the amino acid sequence of prolactin which is displayed in different species. For example; human and canine prolactin differ in about 60% of all the residues. One of the most important functions of prolactin is to stimulate lactation and mammary gland growth. This is evident by the fact that during pregnancy, the levels of prolactin (PRL) in canine blood is increased slightly whereas during lactation, there is a significant increase. There are many other physiological actions of prolactin such as: affecting electrolyte and water balance, vital for stress hormones, metabolism and gonadal function. The measurement of prolactin (PRL) has also be critical during the therapeutic control of hyper-prolactinemia.

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.
