Although CDH26 gene expression has been reported in association with allergic inflammatory responses, the protein expression levels and the signaling pathways mediated through its interactions with other proteins remain poorly understood. This is primarily due to the lack of monoclonal antibodies (mAbs) that can recognize the intact, cell surface-expressed form of CDH26. In this study, we developed an antihuman CDH26 mAb, Ca26Mab-6 (IgM, kappa), using the Cell-Based Immunization and Screening (CBIS) method. Ca26Mab-6 demonstrated high sensitivity and specificity for CDH26 in flow cytometry and did not bind to Chinese hamster ovary (CHO)-K1 cells, which overexpress any of the other type I or type II cadherins. Ca26Mab-6 successfully detected endogenous CDH26 protein expression in HepG2, U-87 MG, MCF7, and 293FT cells. The apparent dissociation constant of Ca26Mab-6 was determined to be 9.8 ± 4.8 × 10-9 M for CDH26-overexpressed CHO-K1 (CHO/CDH26) cells and 3.6 ± 1.0 × 10-7 M for HepG2 cells. The detection of CDH26 expression in cancer cells may offer new insights into the potential relationship between inflammatory responses and malignant transformation. Therefore, Ca26Mab-6, developed using the CBIS method, is expected to facilitate functional studies of CDH26 and contribute to the development of CDH26-targeted antibody-based therapies.","PeriodicalId":53514,"journal":{"name":"Monoclonal Antibodies in Immunodiagnosis and Immunotherapy","volume":" ","pages":"25-33"},"PeriodicalIF":0.0,"publicationDate":"2026-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147391661","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

CXCR2 is expressed on immune cells, especially neutrophils, and is involved in various immune responses by interacting with its chemokine ligands. Therefore, the development of sensitive monoclonal antibodies (mAbs) for CXCR2 has been desired for treatment and diagnosis. This study established a novel sensitive anti-mouse CXCR2 (mCXCR2) mAb; Cx2Mab-5 (rat IgG2a, κ), using the mCXCR2 synthetic N-terminus peptide immunization method. In flow cytometry, Cx2Mab-5 recognized mCXCR2-overexpressed Chinese hamster ovary-K1 cells (CHO/mCXCR2) and WEHI-3B (murine myelomonocytic leukemia cell) cells, which express endogenous mCXCR2. Cx2Mab-5 did not cross-react with other mouse CC, CXC, CX3C, and XC chemokine receptors. Cx2Mab-5 showed a moderate binding affinity for both CHO/mCXCR2 and WEHI-3B. Furthermore, Cx2Mab-5 detected mCXCR2 in Western blot and immunohistochemistry in CHO/mCXCR2 cells, but a commercially available anti-mCXCR2 mAb (clone SA045E1) did not. Hence, Cx2Mab-5 can be a valuable tool for analyzing mCXCR2-positive cells in mouse tissues.","PeriodicalId":53514,"journal":{"name":"Monoclonal Antibodies in Immunodiagnosis and Immunotherapy","volume":" ","pages":"11-20"},"PeriodicalIF":0.0,"publicationDate":"2026-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146222087","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Human CD155 contains membrane-bound CD155 (mCD155) and soluble CD155 (sCD155) lacking the transmembrane region encoded by splicing variants of genes. The serum levels of sCD155 increased in patients with a variety of cancers. Furthermore, sCD155 suppresses tumor immunity through the blockade of DNAM-1 signaling. Therefore, sCD155 is potentially helpful for the diagnosis of cancer development and a novel therapeutic target in cancer treatment. However, monoclonal antibodies (mAbs) specific to sCD155, but not mCD155, have not yet been developed. Here, we generated 14 mAbs (named TX119 to TX122 and TX126 to TX135) that recognize the cytoplasmic region of CD155. These mAbs bind to sCD155, but not mCD155, when applied from the outside of the cell. Moreover, we established the assay system to quantify the sCD155 concentration in human serum. Thus, these mAbs can be utilized for the targeting and quantification of sCD155 in the human peripheral blood.","PeriodicalId":53514,"journal":{"name":"Monoclonal Antibodies in Immunodiagnosis and Immunotherapy","volume":"44 5","pages":"79-83"},"PeriodicalIF":0.0,"publicationDate":"2025-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145294236","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Identifying human blood using various methods is crucial for linking disparate pieces of evidence and solving crimes. In this study, the Anti-Human Hemoglobin antibody (Ah-HB) from Sigma-Aldrich® USA was internally validated for human blood identification using the Ouchterlony Double Immunodiffusion (ODD) technique at the DNA and Serology Department of the Punjab Forensic Science Agency in Lahore, Pakistan. Additionally, a comparative analysis was conducted with Seratec® HemDirect (S_HD) strips to evaluate the economic feasibility of both methods. The internal validation included assessments of sensitivity, specificity, and an analysis of real-case work samples to determine the viability of the antibody as a confirmatory test for human blood. Although Ah-HB had lower sensitivity in detecting human blood at higher dilutions (1:10,000), it offered a more cost-effective solution per sample compared with S_HD, which demonstrated higher sensitivity (1:2,000,000) but at a significantly higher cost per sample. Specificity tests revealed no cross-reactivity with nonhuman blood for both Ah-HB and S_HD. This study emphasizes the importance of selecting suitable antibodies for forensic analysis by evaluating sensitivity, specificity, and cost-effectiveness. Ah-HB emerges as a valuable tool for forensic laboratories, providing reliable results at a lower cost compared with S_HD, thereby enhancing the efficiency and effectiveness of criminal investigations.","PeriodicalId":53514,"journal":{"name":"Monoclonal Antibodies in Immunodiagnosis and Immunotherapy","volume":" ","pages":"71-76"},"PeriodicalIF":0.0,"publicationDate":"2025-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144555713","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
