AP09058041 “Development of immunochromatographic assay for the diagnosis of lumpy skin disease in cattle”

The main idea of the project is to develop an immunochromatographic assay based on the recombinant P32 antigen of the lumpy skin disease virus and monoclonal antibodies to this protein. The project is aimed at solving problems with the spread of the lumpy skin virus in farm animals in the Republic of Kazakhstan. The resulting express test system will reduce the time of diagnosis to 10-20 minutes. The test system is designed to detect antibodies in the serum of cattle suffering from lumpy skin disease.


Lumpy skin disease (LSD) is a transboundary disease and poses a serious threat to livestock production, having a great impact on the economic situation both within our country and in the world as a whole.The morbidity rate among unvaccinated cattle reaches 85%, and the mortality rate is not high, but in some cases reached 40%. Today, in accordance with the requirements of the International Office of Epizootics, cases of LSD are subject to mandatory notification. The causative agent of LSD is a virus belonging to the capripoxvirus family, which also includes Shippox and Goatpox viruses. The disease leads to serious losses in animal productivity, abortions and problems during subsequent insemination, infertility of breeding bulls, damage to the skin, a decrease in live body weight, and costs for health-improving measures. Transmission of the virus from sick animals to healthy ones occurs through blood-sucking insects.

In Kazakhstan, LSD was first registered in 2016, in the Atyrau region. Presumably, the virus was introduced from the territory of a neighboring country, the Russian Federation, where LSD was first registered in 2015. To prevent the disease, 370 thousand heads of cattle were vaccinated in 2018, which had a positive impact on the epizootic situation regarding lumpy skin disease in the country. Considering the widespread prevalence of the virus, the development of an immunochromatographic test based on recombinant antigen and monoclonal antibodies for the diagnosis of LSD in farm animals is relevant for the Republic of Kazakhstan and has scientific novelty.

The final product of the study will be an immunochromatographic test for the diagnosis of LSD. Currently, immunochromatographic test systems around the world are increasingly used in various industries. Immunochromatographic tests are used to determine infectious and internal, non-contagious diseases of humans and animals, to detect drugs and antibiotics in food, etc. It should be noted that in the Republic of Kazakhstan, the use of immunochromatographic test systems is mainly limited to the medical field in determining pregnancy.

Increased interest in immunochromatographic analysis is associated with its rapidity (diagnosis within 10-20 minutes), efficiency (does not require much labor or specialized equipment, which allows examination in the field), and fairly high specificity and sensitivity during mass examination. The availability of an immunochromatographic test for the serological diagnosis of LSD will allow farmers to protect themselves from purchasing sick livestock and thereby prevent further spread of the infection. Using this test system, veterinary specialists will be able to promptly identify sick animals and take the necessary measures in a timely manner.

Project goal

Development of an immunochromatographic assay for the rapid diagnosis of LSD based on the recombinant P32 antigen of the virus and specific monoclonal antibodies.        

Expected results

As a result of the project, an immunochromatographic test will be developed for the diagnosis of LSD in cattle. Strains of E. coli microorganisms producing the recombinant P32 antigen of the LSD virus will be obtained. Diagnostic properties of the recombinant P32 antigen will be studied. Two hybridoma cell lines producing monoclonal antibodies against the recombinant P32 antigen will be obtained. The immunochemical and diagnostic properties of monoclonal antibodies against the P32 antigen will be studied.

Results achieved


A genetic construct carrying the P32 antigen gene was obtained. The resulting DNA fragment was cloned into expression vectors, resulting in genetic constructs carrying the P32 gene. E. coli BL21 (DE3) strains were obtained as producers of the recombinant P32 antigen of the LSDV with a molecular weight of 47 kDa (rP32Trx/pET32) and 32 kDa (rP32/pET28). The main stages of isolation and purification of recombinant P32 protein have been worked out. The results of mass spectrometry (MS/MS) of recombinant proteins analyzed using the MASCOT program confirmed the presence of the P32 antigen of the LSDV.


The immunological and diagnostic characteristics of the recombinant P32 antigen were studied. A scheme for immunization of laboratory animals with recombinant P32 protein has been developed. The main parameters for performing indirect ELISA have been optimized. Two lines of hybridoma cells producing monoclonal antibodies against the recombinant P32 antigen were obtained. Both hybrid cell lines (4E2A11 and 8F2E12) produce antibodies related to immunoglobulin class G, subclass 2b, light chain type – kappa. The binding constant of monoclonal antibodies produced by the hybridoma cell lines 4E2A11 and 8F2E12 was 3×107M-1 and 2×108M-1, respectively. When producing a preparative amount of monoclonal antibodies using the in vitro method, the antibody concentration averaged 43 μg/ml. Using the in vivo method, on Balb/c mice, an average of 4-5 mg/ml was obtained.  


The specificity of monoclonal antibodies obtained to the recombinant P32 antigen was determined. The main parameters for the use of recombinant P32 protein and monoclonal antibodies to the P32 antigen in immunochromatographic analysis have been worked out. It was found that the optimal concentration of protein G (pH 6.0) and monoclonal antibodies (pH 9.0) for immobilization on colloidal gold, with a particle size of 20 nm in diameter, was 20 μg/ml and 12 μg/ml, respectively. The optimal concentration of monoclonal antibodies, antigen and secondary antispecies antibodies applied to the membrane was 200 μg/ml, 500-800 μg/ml and 200-300 μg/ml, respectively. The conjugate and monoclonal antibodies specifically bound to the rP32 protein and did not cross-react with other proteins. The parameters for the formation of an immunochromatographic test were worked out and its diagnostic properties were determined. The sensitivity and specificity of the test were 79% and 90%, respectively.
