Reactivity: Rat
Sample Type: Serum, Plasma, Urine, Cell Culture Supernatant
Sensitivity: 1.68 ng/ml


Leucine rich alpha-2-glycoprotein (LRG) is a protein with a lot of leucine repeats in it. It is crucial for a variety of physiological activities, including as cell adhesion, immunological control and inflammatory response. LRG research sheds light on how our bodies react to sickness and how it might be used as a diagnostic and therapeutic tool. It has different molecular shapes and sizes, depending on its location and function within cells. It can have alternating regions of hydrophobic and hydrophilic regions that are organized in concentric layers.

Cell surface LRGs are the first line of defence, being 2-5 nm long and 10-50 nm wide. They act as an interface between the external cell environment and the internal cellular environment. The hydrophilic regions of these LRGs form part of the external leaflet of the plasma membrane, which is exposed to intercellular aqueous media such as bodily fluids and cytoplasm. This allows for rapid transport between cells and water. It is hydrophobic and inhibits water loss through transpiration. The protein-conducting channel of the human sperm flagellum is a complex network of interconnected LRG proteins. It includes the motor proteins, which have one central LRG surrounded by six other LRGs. The surrounding LRRGs aid in propulsion by creating holes in ECM as they rotate. This leads to hydroplaning off the outer layer of ECM, which is then re-coated. Flagella are only effective in the water and therefore they must be constantly replaced by new ones.


Rat LRG ELISA kit can be used for qualitative measurement of leucine rich alpha-2-glycoprotein (leucine rich alpha-2-glycoprotein, LRG) using rat serum, urine, culture supernatant and EDTA-plasma samples. This assay has a minimum sensitivity detection limit of 1.68 ng/ml.


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.

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.
