Epitope mapping and establishment of a blocking ELISA for mAb targeting the p72 protein of African swine fever virus.

The African swine fever virus (ASFV) has the ability to infect pigs and cause a highly contagious acute fever that can result in a mortality rate as high as 100%. Due to the viral epidemic, the pig industry worldwide has suffered significant financial setbacks. The absence of a proven vaccine for ASFV necessitates the development of a sensitive and reliable serological diagnostic method, enabling laboratories to effectively and expeditiously detect ASFV infection.

[Prokaryotic expression of N protein of akabane disease virus and preparation of monoclonal antibody].

In order to generate monoclonal antibodies against the akabane virus (AKAV) N protein, this study employed a prokaryotic expression system to express the AKAV N protein. Following purification, BALB/c mice were immunized, and their splenocytes were fused with mouse myeloma cells (SP2/0) to produce hybridoma cells. The indirect ELISA method was used to screen for positive hybridoma cells.

Deciphering the role of wound healing genes in skin cutaneous melanoma: Insights into expression, methylation, mutations, and therapeutic implications.

Skin Cutaneous Melanoma (SKCM) is a form of cancer that originates in the pigment-producing cells, known as melanocytes, of the skin. Delay wound healing is often correlated with the occurrence of and progression of SKCM. In this comprehensive study, we investigated the intricate roles of two important wound healing genes in SKCM, including Matrix Metalloproteinase-2 (MMP2) and Matrix Metalloproteinase-9 (MMP9).

Elucidating cuproptosis-related gene SLC31A1 diagnostic and prognostic values in cancer.

Objectives: Cancer remains a global health challenge, necessitating the identification of novel biomarkers and therapeutic targets. Cuproptosis, a recently recognized form of cell death linked to copper metabolism, presents a promising avenue for anticancer strategies. We investigated the clinical significance of SLC31A1, a key regulator of cuproptosis, in multiple cancer types, aiming to elucidate its potential as a diagnostic biomarker, prognostic, indicator and therapeutic target.

Identification of Potential Novel B-Cell Epitopes of Capsid Protein VP2 in Senecavirus A.

Senecavirus A (SVA) is a type of nonenveloped single-stranded, positive-sense RNA virus. The VP2 protein is a structural protein that plays an important role in inducing early and late immune responses of the host. However, its antigenic epitopes have not been fully elucidated.

Colloidal gold and fluorescent immunochromatographic test strips for canine parvovirus detection.

Canine parvovirus (CPV) is an acute and highly infectious virus causing disease in puppies and, thus, affecting the global dog industry. The current CPV detection methods are limited by their sensitivity and specificity. Hence, the current study sought to develop a rapid, sensitive, simple, and accurate immunochromatographic (ICS) test to detect and control the spread and prevalence of CPV infection.

A chemiluminescent magnetic microparticle immunoassay for the detection of antibody against African swine fever virus.

The p30 protein is abundantly expressed in the early stage of African swine fever virus (ASFV) infection. Thus, it is an ideal antigen candidate for serodiagnosis with the use of an immunoassay. In this study, a chemiluminescent magnetic microparticle immunoassay (CMIA) was developed for the detection of antibodies (Abs) against ASFV p30 protein in porcine serum.

Preparation and epitope mapping of monoclonal antibodies against African swine fever virus P30 protein.

African swine fever virus (ASFV) causes acute, febrile, and highly contagious diseases in swine. Early diagnosis is critically important for African swine fever (ASF) prevention and control in the absence of an effective vaccine. P30 is one of the most immunogenic proteins that are produced during the early stage of an ASFV infection.

Development and application of a colloidal-gold dual immunochromatography strip for detecting African swine fever virus antibodies.

African swine fever (ASF) is an acute and highly contagious infectious disease caused by the African swine fever virus (ASFV). Currently, there is no vaccine against ASF worldwide, and no effective treatment measures are available. For this reason, developing a simple, rapid, specific, and sensitive serological detection method for ASFV antibodies is crucial for the prevention and control of ASF.

[Generation and immunogenicity evaluation of Senecavirus A virus-like particles].

To develop Senecavirus A (SVA) virus-like particles (VLPs), a recombinant prokaryotic expression plasmid pET28a-SVA-VP031 was constructed to co-express SVA structural proteins VP0, VP3 and VP1, according to the genomic sequence of the field isolate CH-FJ-2017 after the recombinant proteins were expressed in E .coli system, and purified by Ni+ ion chromatographic method. The SVA VLPs self-assemble with a high yield in vitro buffer.

LAMP assay coupled with CRISPR/Cas12a system for portable detection of African swine fever virus.

African swine fever (ASF) is one of the most severe infectious diseases of pigs. In this study, a loop-mediated isothermal amplification (LAMP) assay coupled with the clustered regularly interspaced short palindromic repeats (CRISPR)/Cas12a system was established in one tube for the detection of the African swine fever virus (ASFV) p72 gene. The single-stranded DNA-fluorophore quencher reporter and CRISPR-derived RNA were screened and selected for the CRISPR detection system.
