Leptospira Hardjo Ab ELISA Kit (Bovine)


Bovine Leptospira hardjo ELISA kit is designed for the detection of antibodies against vital polysaccharide epitope of Leptospira hardjo using samples of bovine serum and milk. This assay has a quantitative and qualitative standard range.


Cattle are regarded as the predominant host reservoir for hardjo and there are two main types of pathogens of Leptospira hardjo for cattle, either interrogens serovar or pomona. The main source of infection arises from direct contact with contaminated urine or through products of abortion. Pomona is found to be more resistant to environmental conditions and also can be less host specific. In general, pomona is found to enter a herd through contaminated water or through infected cattle, whereas hardjo only enter as a result of infected cattle being introduced. ELISA assay take advantage of using monoclonal antibodies that have been standardised in order to effectively catch and detect the specific antigen. Furthermore, the specificity of the monoclonal antibodies which have been utilised in this ELISA kit have been specifically determined by the use of modified microscopic agglutination test (MAT). The following procedure is designed to undertake a rapid screening test in order to specifically detecting Leptospira hardjo antibodies which may be present in either milk or serum samples of infected cattle.


The minimum sensitivity detection limit of antibodies against Leptospira hardjo polysaccharide epitope using current bovine Leptospira hardjo ELISA kit is qualitative and quantitative. Please contact us for the protocol insert for more details.

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.
