Prolactin (PRL) ELISA Kit (Rat)

  • Created on the 29 August, 2018.

INTENDED USE

Rat prolactin ELISA kit can be used to detect quantitative levels of prolactin (PRL) using rat serum samples. This assay has a minimum sensitivity detection limit of 0.6 ng/ml.

BACKGROUND

Rat prolactin (rPRL) is a hormone of the rat anterior pituitary that is a single chained polypeptide having a molecular mass of 23,000. It has been found that prolactin differs considerably between different species, for example; rat and human prolactin differ by approx. 50% of all residues. There is also evidence that the lobe of the rat posterior pituitary contains a prolactin releasing hormone. An important role of prolactin is in the stimulation of mammary gland growth and lactation. High levels of prolactin (PRL) are displayed during lactation, during pregnancy, prolactin levels in the blood can increase, however this elevation can differ greatly between rats. In rats, similar to humans, prolactin is found to exhibit a sleep related diurnal variations. Where nidar value are found in the morning and peak values are displayed in the late afternoon. Finally, in rats, prolactin has a luteotrophic effect and this is not displayed in many of the other species.

SENSITIVITY

The minimum sensitivity detection limit of rat prolactin (PRL) using current rat prolactin ELISA kit is 0.6 ng/ml. The dynamic range for this assay is 5.0 – 80.0 ng/ml.

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.

J. Thomas
Senior Technician / Addenbrooke’s Hospital

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.
